Powder Coating Equipment Buying Guide for New Shops: How to Choose the Right Equipment Package & Supplier

What do you need to start a powder coating shop? 

Reliant Finishing Systems has helped thousands of coaters across the U.S. and Canada, and this guide will explain how to choose the right supplier for your powder booth, curing oven, pretreatment system, and powder gun. There’s even a checklist for comparing vendors.

This article explains why your coating equipment—and the relationship you establish with the equipment provider you select—forms the operational foundation of your new business. The quality of that foundation will influence everything from production quality to safety, long-term cost, and the satisfaction of your customers.

Starting a powder coating shop is not just a matter of buying a booth, an oven, a pretreatment system, and a powder gun. The equipment package you choose and how you lay it out will determine how efficiently you can process parts, how consistently you can produce a quality finish, and how easily you can satisfy code and insurance requirements.

Why Most Shops Start with Batch Equipment

For most new shops, batch powder coating equipment is the practical starting point. The term “batch coating” is used to describe powder coating where parts are organized into batches that will receive the same preparation and powder, then coated and cured manually. Batch equipment is less expensive, more versatile, and easier to operate than conveyorized systems that include automation. Parts are loaded onto racks or carts, moved through pretreatment, coated in a powder spray booth, and cured in a batch oven. When the system is properly sized, well laid out, and supported by a knowledgeable supplier, a new shop can begin production with confidence. When the equipment is poorly engineered or isn’t matched to the workload, the business may spend its first year fighting bottlenecks, rework, and unplanned delays.

Purchasing decisions should be made with patience and discipline. There are numerous companies that provide coating equipment. Some have been around for decades, while others are new to the industry. Most established brands tend to sell based on the features and benefits of their equipment rather than rely on over-the-top sales messaging or budget pricing. Other companies, particularly those at the entry-level end of the market, tend to use low price points, short lead times, and personality-driven sales tactics to attract inexperienced entrepreneurs. 

Recognize the Differences Between Competing Suppliers’ Sales Approaches

Some suppliers manufacture the equipment they offer. They may sell and support the equipment directly or rely on distributors to act as a layer between them and the buyer. Other equipment companies act as sales outlets for equipment made by others. This is especially common with companies that sell less expensive products made outside the United States.

Each company has its own unique sales approach. Some companies rely on price point, promising to “never be undersold,” rather than focusing on equipment quality and support after the sale. Others may promise extremely short lead times. This is a selling point that excites buyers but is usually of limited value when compared to other factors. A few companies use seminars and training classes as part of their sales process. They motivate potential buyers but typically provide only basic information that can be found online. More established suppliers may rely on the reputation of their brand to capture sales. 

When It Comes to Finishing Equipment, Make Sure You’re Comparing Apples to Apples

Making things even more confusing, a prospective buyer can get quotes for booths and ovens of identical size and discover the pricing is all over the map. When looking at equipment that’s 10’ x 10’ x 25’ or smaller, the price difference between national brands and less established brands can be tens of thousands of dollars, even though the equipment seems quite similar at first glance.

Why is this?

The equipment required to manually fabricate smaller ovens and booths is much less expensive than the equipment needed to produce them in volume or manufacture larger equipment, and fewer workers are needed to support the operation. As a result, the market is crowded with small, low-output shops offering inexpensive booths and ovens. 

If you ask detailed questions, you’ll learn that engineering, product quality, performance, and dependability can differ wildly from one brand to another, even though the equipment is the same size. Once you factor in the level of support you’ll receive after the sale, the differences can become even greater. Remember, what’s being offered is more than just a sheet metal enclosure with an exhaust fan or an insulated metal box that gets hot, it’s a solution. 

Not every solution is of equal value, and this is typically reflected in the price.

Avoid the Race to the Bottom

In recent years, the powder coating equipment market has seen a “race to the bottom” at the point where many new buyers enter the market. This is most apparent with batch powder coating equipment packages that include smaller booths and ovens, off-brand powder guns, and sometimes a pretreatment spray wand. These booths, ovens, and starter packages are sold almost entirely on price, often with attractive sales material and aggressive promises, but not always with the engineering depth, practical experience, and personnel needed to support a new business getting into the powder coating arena for the first time.

Trying to build a successful business using light-duty or hobby-grade equipment comes with huge risks. If a booth, oven, or filtration system is undersized or poorly designed, you can run into practical and regulatory problems almost immediately. In the worst cases, equipment may fail to operate properly or meet basic code compliance guidelines, creating risk for the operator, the building owner, the insurer, and customers who are expecting professional quality results on a consistent basis.

Ask yourself this question: Do you really think that an equipment package costing half as much (or less) than one from an established national brand with decades of experience is going to be as dependable on job 1,000 as it was on job 1?

Simply put, the cheapest quote is rarely the best value, especially when your business relies on equipment that needs to operate dependably in a busy shop environment. A low purchase price can indicate poor construction, limited support after the sale, and a lack of attention to code compliance.

Why Reputation Matters

An experienced, reputable supplier offers more than just sales hype and a “catalog” equipment package. They bring design knowledge, installation expertise, a customer support team, and a track record that can be evaluated objectively. In an industry like powder coating, where dependability, process repeatability, and contamination control all matter, choosing a company with a proven technical background is essential.

This is where established national-level manufacturers like Reliant Finishing Systems stand out. Most companies with a decades-old presence in the market have something more valuable than a low price and an attractive sales pitch: they have a reputation to protect. That usually translates into better engineering discipline, more practical guidance for new equipment owners, and a stronger incentive to build equipment that is meant to perform for years on end rather than just sell quickly.

What Cheap Equipment Often Misses

The problems with bargain equipment aren’t always obvious at first glance. A powder booth may look good but have inadequate airflow, improper filtration, or an airflow pattern that works well with wet paint but not powder. An oven may reach the desired curing temperature without incident but suffer from temperature instability once it reaches set point, heat unevenly due to airflow issues, or just plain take too long to get to temp due to an undersized heat system or thermal inefficiency resulting from poor engineering. 

The oven walls and roof may look good from the outside but are only 2” to 4” thick instead of the industry standard of 5” to 6”, reducing overall efficiency due to heat loss. A control panel may be functional on day one but isn’t built with the brand name components and proper safety features to ensure prolonged reliability, serviceability, and code compliance for years of daily use. A no-name powder coating gun may look great in an online video, but if the gun gets damaged or the controls go out due to a power spike, the downtime may stretch into weeks or months while the supplier works with overseas component suppliers to get the right replacement parts.

These types of shortcomings are critical because powder coating is a process business, downtime saps profitability, and small inefficiencies compound quickly. Inconsistent pretreatment can lead to adhesion issues. Poor filtration can increase booth cleanup time and reduce throughput. A faulty gun can lead to inadequate coating thickness. Inexact temperature control during curing can increase rejects. Bad layout can slow throughput. If equipment doesn’t meet code or safety expectations, the cost of fixing the problem later can dwarf the money saved on the original purchase, especially if local code officials red tag the system.

A Checklist for First-Time Buyers

Before making a purchase decision, a buyer should determine whether the supplier understands the real demands of commercial powder coating, not just how to close a sale. The conversation should include a thorough discussion of equipment sizing and placement, booth and oven airflow design, curing performance, maintenance requirements, safety features, code compliance, and installation services including start-up and calibration. 

Use this checklist to make sure you hit the most important topics:

Category

☐

Package Review

Does the quoted package include all equipment, services, controls, start-up support, and accessories needed to begin production? What costs are excluded?

☐

References Matter

A reputable supplier should not only be able to answer these questions thoroughly, they should also be able to quickly provide you with a list of dozens of customers who have equipment similar to what you’re buying. 

These should include customers that have had the equipment for years, not just weeks. You should be able to contact these references directly and talk candidly with them about the equipment and their purchasing experience. 

Contact these references! 

If the supplier fumbles through getting you the list or delays sending it, that’s a problem. If they provide only a handful of customer names, provide a list that includes only very recent buyers, or you find out the contacts listed aren’t legitimate customers of similar equipment, these are all red flags. You’ll also want to look online for ratings from Google and the Better Business Bureau. Read them carefully to make sure shining reviews are from businesses that actually bought comparable equipment.

Tough Questions Don’t Scare Reputable Suppliers

When you purchase capital equipment, you’re buying more than just machinery, you’re buying a long-term relationship with a supplier that can make or break your success. Tough questions push past happy sales talk and reveal whether the seller will become a valuable partner or remain just a vendor. Don’t be afraid to ask hard questions like how many full-time engineers do they have on staff, how many installation crews do they employ, and do they offer repair and maintenance services. These questions will help you determine if the company you’re about to do business with has the resources to provide you with a well-engineered solution and support it fully.

The Cheapest Package Can Become the Most Expensive

The true cost of a powder coating system is not just the quoted purchase price. Buyers should also consider utility consumption, the potential for rework due to rejected parts, throughput limitations, the availability of replacement parts, warranty duration, the cost of support after the sale, and any factors that can lead to lost production time. A system that seems more affordable but causes recurring problems may cost more within the first year or two than a better-built system with a higher initial price.

Use a Business-Minded Approach

The right mindset is to treat your powder coating equipment purchase as an investment in operational performance and reliability, the two most critical factors for profitability.

A business that buys carefully may take longer to launch or spend more money up front, but it will typically encounter fewer frustrations and unplanned expenses. It will usually have less downtime, better finish quality, fewer compliance headaches, and a stronger chance of quickly becoming profitable. For businesspeople entering the powder coating market, the goal shouldn’t be to just open the doors. For greatest success, the goal should be to build a business that can scale, protect its reputation, and produce work that customers trust.

Poor Process Balance: The Overlooked Powder Coating Problem

,

For all powder coaters, especially larger industrial powder coating operations, the most expensive problems are not always caused by bad powder, poor equipment, or careless employees. Instead, their coating line’s effectiveness may be getting clobbered by something less obvious. Whether using a batch or conveyorized powder coating system, the real issue in many facilities is process imbalance. The pretreatment system, dry-off oven, powder booth, application equipment, conveyor/cart movement, and curing oven may all function individually at what seems like an acceptable level, but they may not function well when viewed as a coordinated production system.

That distinction matters because small issues throughout the coating process become roadblocks to profitability once they pile up. A successful powder coating operation is more than just a group of machines and operators. It should be a controlled manufacturing process. When one phase of the process is poorly maintained, log-jammed/undersized, improperly adjusted, or out of sync with the rest of the process, the entire operation suffers. The results usually show up as slow throughput, excess labor, wasted powder, substantial rework, inconsistent film thickness, poor adhesion, unusually long cure windows, or operators making constant adjustments to compensate for system-level problems.

Bart Roegner, CEO of Reliant Finishing Systems, observes, “A fair amount of our business comes from companies that already know powder coating, but still can’t get their finishing line to produce the results they need. Sometimes the problem is obvious. A worn-out multi-stage washer. An oven that was never built for the current workload. A line that has been pushed past what it can reasonably do. Other times, it is not one big failure. It is ten smaller failures stacked on top of each other until the whole system starts failing. Those are the jobs we like. We can step back and look at the coating operation as a system. We are not buried in the day-to-day frustration. We are not worn down by the same recurring problems. We can see the line clearly, identify what is actually driving the failures, and apply experience the customer may not have internally. That is one of Reliant’s real strengths: we solve system-level finishing problems without overcomplicating things.”

Let’s move through the finishing process step-by-step to identify potential areas of concern, starting with parts prep. The vast majority of finish defects are caused by improper parts preparation. Pretreatment should always be evaluated as a component of the full coating process, even if it takes place elsewhere (such as when parts are blasted off-site before being coating). A well-designed pretreatment process removes soils, improves surface condition, and supports adhesion and corrosion resistance. However, if parts leave pretreatment with blasting debris, trapped moisture, chemical residue, or inconsistent surface preparation, the other equipment in the process can’t fix these problems. That’s why it is critical to routinely review chemical concentration, rinse quality, water condition, nozzle performance, dwell time, and dry-off effectiveness for chemical pretreatment systems, and blast nozzle wear, compressed air quality, and blasting media choices when mechanical surface preparation is required.

Once pretreatment performance has been reviewed, including the performance of the dry-off oven if one is in use, the next step is to consider the powder coating booth and what takes place inside it. There’s a lot that can go wrong without giving immediate warnings. 

As an example, coating inefficiencies aren’t always glaringly obvious. First-pass transfer efficiency is one of the most important metrics you can measure. In a larger industrial setting, even a modest improvement can have a major financial impact. If a plant applies hundreds of pounds of powder per week, improving transfer efficiency by only 10% can reduce powder waste, coating time, filter maintenance, reclaim handling, and cleanup time. Better transfer efficiency also tends to improve consistency because operators aren’t fighting the system to get adequate coverage.

Grounding is a related issue that deserves regular attention. Poor grounding reduces powder attraction and makes it harder to coat quickly and efficiently. Hooks, racks, carts, conveyor components, and other contact points should be inspected periodically for powder build-up. A part that appears to be grounded because it’s hanging from grounded equipment may still have a poor ground path if the contact surfaces are insulated by coating residue. In addition to clean contact points for parts, it’s not uncommon for supplemental grounding to be necessary for achieving optimal results. This is often done using copper grounding rods and heavy gauge grounding straps at the booth. In all coating operations, especially ones that routinely see a large volume of parts traffic, grounding should be treated as a high-value maintenance item, not a one-time setup detail.

Parts orientation and hanging schemes are also important. Some coaters, especially fabrication job shops and powder coating service providers, process a wide mix of parts. Inconsistent loading patterns can create inconsistent results. If parts are hung too close together, airflow and powder cloud movement may be restricted. If parts are oriented poorly, painters may have to over-apply powder to reach hidden surfaces or reposition carts by hand to gain access. Better organized racking and spacing can improve finish quality without changing the powder or the equipment.

Another common issue is poor airflow balance in the powder booth. Industrial powder booths must capture overspray effectively, but excessive airflow can pull charged powder away from the parts before it has a chance to adhere. This is most common in undersized booths, where the displacement caused by the load leads to excessive air velocity around the part. The same thing can happen if a portion of the load is too close to the exhaust filter surface. When these issues occur, first-pass transfer efficiency drops. The booth interior may look fairly clean, and the exhaust system may appear to be working well, but the company is spending more on powder, filters, and labor than necessary.

At the other extreme, some booths have inadequate airflow, often due to clogged filters. In fact, poor filter maintenance is probably the number one cause of powder booth performance issues. Insufficient airflow can cause the powder cloud to hang in the air around the part after an appropriate amount of powder has already coated the surface. The painters must deal with decreased visibility, which can lead to errors. The powder overspray eventually falls to the floor in the workspace without being moved towards the exhaust. The painters end up dealing with a heavy film of powder underfoot, which can be a safety issue, plus the wheels on rolling racks get soiled with powder build-up more quickly. This situation necessitates increased booth cleaning labor and can also lead to incidental cross-contamination issues when changing between powders during the workday.

Similarly, airflow issues inside the curing oven can limit productivity. A powder curing oven needs adequate, evenly distributed heated air across the entire work envelope. If airflow is weak, uneven, or blocked by poor part spacing, some areas of the load may reach cure temperature much later than others. Operators may respond by increasing dwell time or raising the setpoint. That may help the worst-case part cure properly, but it can also increase fuel consumption, slow production, and risk overbaking lighter or thinner parts. If heavy parts and light parts are mixed without considering cure response, some parts may be under-cured while others are exposed to unnecessary heat.

Even with ovens that are designed with a substantial work envelope where temperatures are relatively uniform and airflow is appropriate, poor hanging practices can lead to problems. This is most commonly found in batch coating situations where managers are pushing for maximum throughput or employees haven’t been properly trained. Operators end up racking parts well outside the oven manufacturer’s designated curing envelope. This happens by jamming parts against the discharge points of the oven’s heat system or hanging them too close to the floor or doors. The parts end up being blasted by hot air that hasn’t had a chance to normalize across the curing zone or located in an area inside the oven that will never have adequate curing performance.

As mentioned earlier, finishing operations should evaluate powder coating performance as a complete process instead of troubleshooting each defect in isolation. For example, adhesion failure may be blamed on the powder or the curing routine, but the root cause could be poor pretreatment. Surface defects like orange peel may be blamed on the gun settings, but the real problem may be that the parts are too hot coming out of the drying oven, taking too long to get to temp in the curing oven, or you’re dealing with excessive film build caused by repeated touch-up. Color inconsistency, particularly with whites and light colors, may be blamed on the supplier, while the actual cause may be inconsistent cure temperature or contaminated reclaim powder.

Bart Roegner adds, “A useful starting point is to measure the entire coating process in practical terms. You may find that easier and more useful than trying to drill down on the technical aspects right away. It’s rare that you can fix everything all at once, so after you get an objective look at the big picture, you can prioritize your efforts.” 

Typical questions might include:

How many different parts are coated in a typical day/week/month and what size are they? 

What is the target film thickness and what’s currently being achieved?

How many pounds of powder are purchased versus how many pounds are actually deposited on saleable parts? Has this shifted when changing powder vendors or using different products?

How often are parts recoated or touched up? Are the types of failures recorded and tallied?

How many operators are needed at each stage of the process to get maximum productivity? How many do we have now?

How much time is lost each day/week/month waiting on pretreatment, drying, booth availability, or oven capacity? Is there a log showing what phases of the process caused delays?

How much time is lost each day/week/month due to unplanned equipment downtime? Is there a log of what appliances were down and why?

Getting answers to these questions can reveal whether the current coating operation is an effective production asset or an ongoing fight against bottlenecks, waste, and defects. If these answers aren’t immediately available, a good first step (if you’re not dealing with an emergency due to powder coating issues at your facility) would be to put systems in place so you can get the information you need to make objective decisions.

The best powder coating systems are designed around the work being processed. Part size, material thickness, production volume, coating specification, available labor, floor space, handling method, and future growth plans all affect equipment selection. A booth, oven, washer, or conveyor that looks adequate on paper may not deliver the desired output if the full operating pattern is not considered.

This is where experienced system design matters. Reliant Finishing Systems works with manufacturers, fabricators, and coating operations that need practical, dependable powder coating equipment built around real production requirements. For industrial coating operations of all sizes, the goal should not be to simply to buy an adequately sized equipment package. The goal should be to create a balanced coating process that maximizes throughput, reduces waste, supports consistent quality, and gives the company room to grow.

A well-balanced powder coating operation does not depend on constant operator correction by experienced, highly skilled employees. It gives even inexperienced, moderately skilled operators the right conditions to succeed. Airflow, heat, grounding, pretreatment, part movement, and application technique all work together. When those elements are properly matched, the result is lower operating cost, better finish quality, fewer rejects, and a more profitable coating department.

Succeed By Starting 2026 Focused on Powder Coating

In business, preparation is often the difference between keeping up and pulling ahead.

For manufacturers and fabricators, the beginning of a new year is more than a calendar reset. It’s a strategic inflection point. Budgets are fresh, lessons have been learned from the previous year, production forecasts may be clearer, and competitive pressure rarely waits for “later in the year.” As 2026 starts, many manufacturers and industrial service companies are asking a critical question:

Does it make sense to invest in powder coating equipment now, rather than continuing to outsource or delay buying?

For a growing number of manufacturers and fab shops, the answer is yes. The reasons go far beyond product aesthetics or business convenience.

  1. Capital Equipment Is a Growth Multiplier, Not Just a Cost

Turn-key powder coating systems, industrial spray booths, powder curing ovens, and manual or automated pretreatment systems are often viewed as major expenses. In reality, if intelligently sourced and properly designed, they function more like force multipliers.

When finishing operations expand or move in-house, companies gain:

  • Greater control over schedules instead of waiting on subcontractors or dealing with outdated or undersized equipment
  • Predictable per-part costs instead of fluctuating outside pricing or unexpected upkeep expenses
  • Faster lead times, which directly improve profitability and boost customer satisfaction
  • The ability to take on more work without increasing overhead proportionally

For job shops and large-scale fabricators, professional quality in-house finishing capabilities allow them to quote complete, turn-key jobs rather than losing margin to outside vendors or struggling with aging equipment. For OEMs and manufacturers, it can mean stabilizing production flow and eliminating a major bottleneck.

Starting 2026 with new finishing equipment that has been installed and tested means those gains begin in Q1 or Q2 instead of later in the year.

  1. Fortune Favors the Bold

Every year, countless businesses across numerous industries consider bringing coating in-house, updating or expanding their existing coating capabilities, or decide to switch from wet paint to powder–but then DON’T. For some reason, one or more people within the organization just can’t seem to pull the trigger. They may have the resources to move forward but choose to keep doing what they’re doing. 

Michael Schuerer, the president of Reliant Finishing Systems, has over 25 years of experience in the industry. He observes:

“We sometimes encounter businesses that can’t quite commit to a new powder coating system despite indicators of future success. They tend to get in touch after they’ve lost a big contract, encountered an in-house failure that led to catastrophic results, or got dismal news on a P & L. They’ll show intense interest, then they’ll sort of fall off the radar. 

This is sometimes followed by a period of renewed interest months or years later, usually after another big failure, then another period of silence. We’ve had some customers do this multiple times over a period of five years or more. Once they finally decide to buy, they’re nearly in panic mode. It becomes more difficult to guide them towards smart, business-savvy decisions because they’re so highly pressurized by their circumstances. 

At the other end of the spectrum, we’re frequently contacted by companies who are being proactive, have allowed themselves enough time to get their new system up and running, and can make the smartest business decisions. Out of the thousands of companies Reliant has interacted with, I can’t think of a single one that later regretted investing in powder coating. The vast majority of them say they wished they had made the move sooner.

The main take-away I’ve gotten is that companies that will truly benefit from having professional-quality powder coating capabilities should do their homework, avoid pitfalls like buying used equipment or settling for off-brand products, partner with a reputable company they are comfortable working with, and give themselves enough time to make smart choices. This means getting out in front of the situation and acting to strengthen their business rather than playing catch-up after they’ve already lost ground.”

Many company leaders only begin shopping for finishing equipment once they’re already overloaded, behind schedule, suffering quality issues, and/or losing work.

The most successful businesses take the opposite approach. They invest when they still have room to plan, specify, and implement correctly—before finishing capabilities become a constraint instead of a competitive advantage.

Starting 2026 with a strong equipment strategy allows decision-makers to focus on growth instead of firefighting.

  1. Outsourcing Finishing Is More Expensive Than It Seems

On paper, outsourcing powder coating or industrial painting may appear cheaper than it actually is. Experienced manufacturers know that hidden costs add up quickly:

  • Transporting parts back and forth to the coater either extends lead times, adds pressure to in-house personnel by reducing production timelines, or both
  • Freight expenses related to outsourcing can be unexpectedly costly, especially if rush shipment is required
  • Additional handling is always required, and additional crating is commonly needed for transport
  • Damage or rework due to extra handling steps are hidden risks
  • Missed ship dates due to third-party delays are common
  • Limited flexibility for rush orders or design changes can result in missed sales
  • Finish quality issues are often not discovered until the last minute–or after products have already been delivered to end-customers

When those factors are considered, many companies discover that the true cost of outsourcing finishing is far higher than the per-part invoice suggests.

Investing in your own finishing line converts those variable costs into a controlled, scalable operation, often with a surprisingly short payback period.

  1. Early Investment Aligns with Real-World Production Planning

One of the most overlooked advantages of investing at the start of the year is timing.

When equipment is ordered early:

  • Installation can occur before peak production seasons
  • Operators can be trained without full production pressure
  • Process issues are resolved before customer demand spikes

Companies that wait until Q2 or Q3 often find themselves trying to install equipment during their busiest months, when downtime is least tolerable.

Instead, by planning ahead and acting decisively, a company can end Q1 or start Q2 with a powder coating system that’s already been installed and de-bugged. Since their coating operation is already up and running, they’re poised to instantly capitalize on mid-year demand rather than react to it.

  1. Powder Coating Continues to Win on Performance and Efficiency

Powder coating remains the preferred finishing method for a wide range of industrial products because it delivers tangible operational advantages:

  • High durability and corrosion resistance = greater long-term finish performance
  • Consistent finish quality and appearance = improved customer satisfaction
  • Minimal waste compared to liquid coatings = lower applied cost
  • No solvents and minimal VOC concerns = reduced environmental hassles

Modern powder coating systems from reputable manufacturers like Reliant Finishing Systems are also more efficient than ever! Improvements in gun technology, booth airflow design, and oven heating controls reduce energy use while increasing throughput.

For manufacturers planning ahead to 2026 and beyond, investing now ensures they are operating with current-generation efficiency, not outdated equipment that costs more to run every day.

  1. Reliant’s Finishing Systems Are Designed for Scalable Growth

Reliant’s powder coating and industrial painting systems aren’t “one-size-fits-most.” Their equipment is well-designed, modular, configurable, and scalable.

That means manufacturers and job shops can:

  • Start with batch systems sized for their current or near-future volume
  • Add capacity later without replacing the entire system
  • Easily adapt to new part sizes, materials, or coating requirements
  • Switch to more sophisticated automated processes as demand warrants–while retaining or integrating their batch equipment as appropriate

This scalability is especially attractive to small and mid-sized manufacturers and fabricators who are planning for growth but want to invest prudently.

A properly designed coating system doesn’t just solve today’s problems; it supports tomorrow’s opportunities.

  1. Workforce Efficiency Matters More Than Ever

Labor remains one of the most significant challenges facing manufacturers post-COVID. Equipment that reduces personnel requirements, minimizes labor intensity, or simplifies training requirement delivers real ROI.

A new powder coating system from Reliant Finishing Systems can:

  • Reduce manual handling through better parts flow
  • Improve first-pass yield, reducing rework
  • Eliminate bottlenecks that lead to additional handling labor
  • Simplify operation with intuitive controls and layouts

For companies dealing with tight labor markets, investing in better equipment is often more effective than trying to hire additional personnel or tolerating difficult employees.

  1. Quality and Consistency Protect Your Brand

In competitive markets, finish quality is not just cosmetic, it’s reputational.

In-house powder coating (or painting) allows manufacturers to:

  • Enforce consistent quality standards
  • Respond instantly to quality issues
  • Maintain tighter control over color, cure, and coverage
  • Offer unique finishes that may not be available from third-party coaters

Customers notice consistency and recognize premium quality finishes, even if they can’t articulate it. Over time, your ability to consistently provide excellent powder coated finishes becomes part of your brand’s value proposition.

  1. Capital Investment Sends a Signal—to Customers and Employees

Investing in dependable, well-made production equipment sends a powerful message!

To customers: We’re serious about quality, capacity, and reliability. We’re advancing our capabilities and improving our offerings.

To employees: We’re investing in better tools and long-term growth. We’re positioning the company for greater success.

These messages matter, especially in industries where quality work is valued, long-term relationships drive repeat business, and trustworthiness differentiates successful businesses from their competitors. They also help ensure smoother business operations by making it easier to retain future-minded employees.

Put Simply, 2026 Favors Prepared Businesses

Your new powder coating equipment shouldn’t be an impulse purchase. It’s a strategic investment that shapes production efficiency, cost structure, and customer satisfaction for years to come.

For manufacturers, fabricators, and job shops looking ahead, the question isn’t whether the finish their products receive matters, it’s who controls it.

Those who enter 2026 with dependable, properly designed finishing equipment from respected manufacturers like Reliant Finishing Systems will be better positioned to deliver faster, more consistent, and more profitable work than those still relying on outdated equipment or outsourced solutions.

Powder Curing Oven Comparison Guide for Professionals

,

Considering new powder coating equipment for your business? When you’re getting quotes, make sure you’re comparing apples to apples, especially when it comes to the powder curing oven! This easy-to-understand guide from Reliant Finishing Systems helps you quickly evaluate the features that can make or break your success.

Key Features—Start by evaluating the quality of the oven’s design & components

Does the oven have a fully modular design?

Ovens that have a fully modular design, like those built by Reliant Finishing Systems, can easily be expanded in size in the future with no field welding required. Many entry-level products from oven “catalog websites” aren’t truly modular in design and can be expensive or impossible to expand in the future. The same applies to many powder curing ovens offered by higher-end oven companies, because the number of custom components and/or the amount of welding involved makes expansion costly and impractical.

Can heat units or exhaust systems be relocated in the field if there is an unforeseen issue with oven placement?

 Sometimes things don’t go as planned while you’re setting up a new coating operation. A couple oven manufacturers, including Reliant, have ovens designed so the exhaust and heat system can be placed in multiple locations during assembly without modifying the equipment or compromising the oven’s performance. With other brands of ovens, the layout can be expensive or impossible to reconfigure.

What burner does the oven use?

Make sure the oven has a brand-name burner from an established burner manufacturer such as Power Flame or Maxon. These burners are more expensive, but they ensure that your oven’s heat system will be safe to operate. By selecting one of these burners, you’ll also have easy access to repair and maintenance parts. You should check to confirm that the burner model being used has been tested and certified for oven use (this is indicated by an ETL or UL listing decal that has been applied to the burner by the manufacturer). Reliant Finishing Systems uses specially configured Power Flame burners that have been approved for oven use and proven on thousands of ovens across the U.S. and Canada.

What motors does the oven use?

Avoid ovens that use no-name motors because these can lead to troubleshooting and replacement issues in the future if you have a problem with your oven. Reliant, and some other manufacturers of high-quality powder curing ovens, integrate energy efficient and dependable Baldor heavy duty motors for both their heat systems and exhausts. As with other premium components, these may cost more but are a smart investment.

Does the oven body ship assembled?

Although a few companies tout the benefits of shipping pre-assembled ovens, most oven manufacturers provide their products unassembled to prevent shipping damage and allow for installation in hard-to-reach spots. This approach makes the oven much easier to unload and avoids situations where customers find it impossible to install their new equipment due to the layout of their shops.

 Where is the exhaust located?

 Reliant mounts their oven exhaust to the floor, so it removes only the coolest air in the oven–reducing heating costs. Some other companies mount the exhaust on the oven roof, drawing out the hottest air and wasting heat energy.

Where is the heater located?

For ease of inspection and maintenance, look for a heat system that mounts to the floor and has the gas train and burner components at about chest height. If possible, avoid roof-mounted heat systems that are more challenging to adjust and service. Reliant ovens typically use floor-mounted heaters. Roof-mounted versions are available if space constraints require them, but are not recommended for most applications.

 Where is the hot air discharge plenum located?

Reliant typically uses an overhead plenum that mounts above the entire ceiling of the oven because it uses no extra floor space and provides uniform airflow to the entire oven interior. Some companies use plenums that mount to one or both sides of the oven body (or the rear) using up lots of extra floor space.

Does the oven have a floor?

Reliant offers the choice of a steel floor, an insulated floor, or no floor at all. Most batch powder coating ovens don’t have a floor or have only a basic steel floor. This is because most shops use rolling carts, so an insulated oven floor isn’t practical. If your process could benefit from an insulated floor (such as when using an overhead rail to support parts hanging from hooks), make sure the oven provider has the ability to supply the best floor solution for you.

How is the oven controlled?

Reliant offers the choice of push button control panels with digital temperature management features or more elaborate color touch screen controls (with or without integrated data logging). Some oven companies provide only touch screen controls. For many customers, these don’t offer any benefits, but they are more expensive, can be more challenging to operate, and are more difficult to service. At the other end of the market, most entry-level oven websites offer only primitive push button controls that may or may not meet applicable codes.

Oven Construction—the difference is in the details

How heavy is the insulation? (heavier is better)

Almost all powder curing ovens are insulated with mineral wool. Mineral wool is supplied to the oven manufacturers in sheets. The denser the insulation, the more effective it is. Reliant ovens are insulated with mineral wool of 6# density or greater. Some oven builders use less expensive (and less effective) insulation of 4# density or less.

How thick are the walls & roof? (thicker is better)

Reliant powder curing ovens have wall and roof panels that are 6” thick. Some other well-known oven companies have wall and roof panels that are only 5” thick.  Economy-priced ovens may have panels that are only 4” thick, and some catalog sites sell ovens with panels that are less than 4”, practically guaranteeing unnecessary heat loss and significantly increased shop temps near the oven.

How thick are the doors? (thicker is better)

It’s important that your oven’s doors are well insulated to prevent heat loss. Reliant’s standard oven doors are over 5” thick and have gasketed overlapping closure flange to minimize heat loss. Many other ovens on the market use doors that are only 4” to 5” thick, and budget ovens may have doors that are even thinner—some 3” or less. If roll-up doors are best suited for your application, look for insulated fabric doors like those provided by Reliant.

Is the door assembly self-supporting?

 Many premium oven brands, like Reliant, utilize oven doors that are self-supporting and easy to adjust. These doors don’t need casters or supports. Some inexpensive ovens rely on troublesome casters to help support the doors.

 What material is used for the oven’s panels and exterior skins?

 Reliant uses prime U.S. steel from matching lots. Other companies may use U.S. steel from random lots, non-prime steel, or imported steel. Ask what type of steel the oven builder uses and where it originated. 

How is the steel used for these panels treated?

 Reliant uses only G90 galvanized steel panels to ensure long life and corrosion resistance. Some companies use less expensive and less corrosion-resistant G60 galvanized steel or generic galvanized steel that hasn’t been treated to any set standard. You’ll also find aluminized panels or powder coated panels from some manufacturers. Many less expensive ovens have panels that have only been painted or are left untreated.

 How are the panels that make up the oven body fitted together?

It’s important that the oven panels are secured in place before the oven is used. Reliant’s panels bolt together in field, assuring the snuggest fit. Some ovens use friction fit panels that are secured with screws. Others use panels that are only held together by a friction fit method, and a few inexpensive ovens rely on self-tapping screws to fasten the panel parts together.

 Are the panels insulated in the field during installation?

 Reliant ovens are unique because the panel assemblies are shipped as separate components. The insulation is applied during installation, ensuring perfect insulation placement. Ovens that rely on pre-built panels can be less efficient because the insulation can degrade slightly and settle during transport—leaving the tops of the panels without proper insulation once installed.

 Is all the oven’s advertised interior space usable?

 With some oven brands, a portion of the advertised interior space has ductwork in the way, reducing the amount of room available for curing parts. With Reliant and most premium brands, the entire advertised space is available for use.

Are the oven doors full size, allowing straight-in access to the entire oven interior? Do the doors hinge back out of the way?

Most higher-end ovens, including those from Reliant, use doors that provide access to the entire oven interior. Some ovens, however, use doors that are inset and slightly smaller. This reduces the cost of the doors but blocks straight-in access near the walls and ceiling. Remember, a reduction in clearance of only a few inches can significantly limit how you go about loading and unloading the oven. Along the same lines, most premium ovens, like those from Reliant, include doors that swing back more than 90° and clear the front of the oven. Some less expensive ovens use doors that swing open but don’t swing back out of the way. This means you’ll have to consider the turning radius of the cart you’re using because you may have to turn the cart more abruptly to clear the doors because they stick out straight in front of the oven—slowing the loading/unloading process and reducing throughput speed.

Company Information—Who are you buying from? 

Does the salesperson work directly for the oven manufacturer or are they a distributor/rep/contractor/reseller?

Reliant (and other companies that utilize full-time employees to sell equipment) can establish closer relationships with their customers and avoid the delays and miscommunication that can happen when there are layers of middlemen between the people designing and building the equipment and the people who’ll be using it.

Is their oven manufacturing facility in the U.S.?

There are a few newer brands on the market that don’t have US-based manufacturing capabilities. This can lead to issues with repair or replacement parts, technical advice, and support after the sale.

If you’re considering buying from an oven manufacturer, have they always made their own ovens?

Companies, like Reliant, that build their own equipment will have more experience and can provide greater control over product quality, lead times, and technical support. There are a handful of companies that started building ovens in the last few years (after selling equipment made by others), but their info may lead you to believe they’ve been manufacturing for decades. Don’t be shy about asking detailed questions, like “How long have you built your own ovens and exactly how many has your company built?” For comparison, Reliant has been manufacturing since 2005 and has manufactured over 1,000 ovens specifically for professional powder coating applications.

Do they start-up and calibrate their ovens using in-house technicians?

Hands-on calibration ensures that the oven is safe to operate and has been tuned for maximum fuel-efficiency and reliability. Many batch oven providers don’t offer on-site calibration. A few provide basic start-up services but rely on contractors. Premium-brand oven companies, like Reliant Finishing Systems, offer comprehensive start-up & calibration services using in-house technicians. Reliant provides these services at no additional cost.

Does the provider offer phone support by full-time in-house technical specialists? How many full-time support people do they have to assist their powder coating equipment customers?

Once your oven is operational, it’s important that you’ve got someone to call when there’s an unexpected hiccup. Whether it’s a lightning strike knocking out your power, an employee bumping the heater with a forklift, or just a situation where you need coating or curing advice, support after the sale can make a huge difference to your profitability. Additionally, Reliant offers lifetime over-the-phone support for all Reliant equipment. Monday through Friday, our in-house service team of experts (not call center operators or useless AI “assistants”) is on standby to help troubleshoot any issues or answer questions you may have. We have a team of experienced full-time employees who are on standby to support our customers, so you won’t be left hanging when urgency is critical. Some companies offer support only for the duration of the warranty. Others offer support but only have one or two employees who are qualified to provide troubleshooting guidance. A few have no established phone support program at all or direct you to contractors who charge for their services.

How good is the warranty?

It’s an unpleasant fact that sometimes parts fail. How this impacts your bottom line depends on the quality and duration of your oven’s warranty. When you do business with a top-tier oven manufacturer like Reliant, you can feel confident that your equipment will be supported for years to come. Many entry-level oven companies offer warranties that range from as little as 30 days up to 1 year. They may or may not include free shipping for replacement parts, and some have complicated requirements where old parts must be returned, or a deposit paid before your replacement parts are shipped. Reliant Finishing Systems has one of the best warranties in the industry. We cover all oven components, including belts, for 2 full years. If you’ve got a defective part, we’ll cover ground shipment of the replacement, and we offer express shipping at a reasonable charge. Since we’re the manufacturer and not just a sales outlet, we always have a huge inventory of repair and maintenance parts in stock. Because we use brand name components, you won’t be locked into buying from us down the road once your warranty expires. Many parts can be sourced from local suppliers or companies like Grainger. Additionally, Reliant offers lifetime over the phone support for your Reliant equipment. Monday through Friday, our in house and live(not a call center) Service Team is on standby to help troubleshoot any issues or questions you may have.

Does the company offer professional installation and maintenance services?

One way to understand the support you’ll receive in the future is to assess the capabilities of the company you buy your oven from. Some premium powder coating equipment companies, like Reliant, have teams of in-house technicians who can be deployed to perform installation and service work. Others may use contractors for on-site work. Some require you to work with the distributor who sold you your oven. Many online sales sites don’t offer field support at all. When you buy a standard powder curing oven, Reliant allows you to choose whether you’d like to install the oven yourself, hire your own contractors, or use our in-house techs to assemble your oven and perform interconnection wiring. Many companies choose to have their ovens installed and serviced by our techs so they can keep their workers on-task and keep their operation rolling.

As you can see, there’s more to buying a powder curing oven for your business than just comparing prices. By asking the right questions and weighing the features and benefits that are important to your success, you may not select the least (or most) expensive alternative, but you’ll get the equipment that offers the greatest value for your company.

Understanding Powder Coating Cure Times & Temperature Settings: A Powder Coater’s Guide to Getting Great Curing Results Every Time

A convection powder curing oven from Reliant Finishing Systems with heated air make-up and control panel

This article will be most helpful for businesses using gas-fueled convection curing ovens in a batch curing setting. Gas-fueled convection ovens are the most popular ovens for professional powder coating situations. Conveyorized powder coating systems also typically use gas-powered ovens, but the dwell times are established by the conveyor rate. Although electric powder curing ovens are out there, and the information here applies to them as well, they tend to be much smaller in size and are primarily used by hobbyists.

Let’s Start by Identifying the 2 Most Common Powder Curing Problems:

An industrial steel part with gray powder coated finish

Undercuring leads to soft (or sometimes brittle) film, poor adhesion, reduced chemical resistance, and early finish failure. 

Paint booth panels with white powder coated finish

Overcuring is usually more forgiving. Most modern powders tolerate a moderate amount of extra time/temperature with only a mild change to the gloss or final color. Some white powders will “tell on you” by yellowing if they are exposed to excessive curing temps or dwell times. But, as a general rule, if you must choose, undercuring is worse than slight overbaking.

Next, Consider Your Powder Curing Oven’s Performance Characteristics

A Reliant gas-fueled convection powder curing oven

Powder curing ovens from reputable manufacturers like Reliant Finishing Systems provide excellent curing results because they heat the parts evenly and return to operating temps quickly when the doors are opened or the oven is shut down between batches. Look for models with thicker, better insulated wall and roof panels (6” is ideal), along with robust heat units with powerful recirculation fans.

Infrared (IR) ovens provide faster surface heating and work great for thin parts with simple geometries, such as panels and flat sheets, but they can create uneven surface temperatures on complex or dense parts if used as the only curing appliance. They are also typically much more expensive than convection curing ovens.

Although the most costly, hybrid ovens offer a nice mix of the performance benefits of both convection and infrared ovens. An IR section provides the initial heat-up of the powder (sometimes called the pre-gel phase), while also raising the temperature of the substrate. The convection section then evens out surface temps across the load and finishes the curing process.

IMPORTANT: Uniformity Trumps Frantic Speed (Think Slow is Smooth, and Smooth is Fast)

It’s tempting to focus on how fast your oven reaches setpoint and try to make every batch a race—especially in a busy job shop or heavy production environment—but ignoring load temps and secondary factors can be a costly mistake. Instead, focus on doing things the same way every time you deal with a similar load. Concentrate on getting uniform results, even if it takes a little longer. 

An operator at the controls of a powder coating system

This begins by understanding your oven’s capabilities and using them to best advantage. The oven can be fine-tuned during the initial set-up and calibration, and again whenever the oven is being periodically serviced. Some high-end oven companies, like Reliant Finishing Systems, send a technician to inspect the oven, start it up, calibrate it, and test its performance. They will even train your operators on how to operate and maintain the oven for best results. While on-site, techs will typically refine burner performance, verify temperature uniformity across the usable workspace, adjust recirculation airflow, tweak discharge duct output, and check for heat leakage. But their assistance doesn’t end once the oven is up and running. Reliant customers receive free lifetime phone support, including help troubleshooting temperature or tuning issues that may occur down the road when working with unusual parts or dealing with seasonal changes in the gas supply.

Once the oven is operating properly, it is important to keep burners, fans, ductwork, safety devices, and doors seals clean and well maintained. Spotty burner performance and improper airflow can cause inconsistent curing.

One of the most overlooked issues impacting both throughput and finish quality is “style of use.” Simply put, it means how you operate and maintain your equipment. A review of multiple shops doing similar work will typically reveal that some businesses get much better results from the exact same equipment. 

There are obvious reasons why. Shops that take better care of their equipment have fewer unplanned oven shut-downs and less downtime overall. Along the same lines, shops that try to boost throughput by cutting dwell times short or running their oven at excessively high temps to shorten their curing routines often encounter higher reject rates due to curing issues. 

Other problems may be less obvious. Some operators fail to maximize oven space by inefficiently racking their parts. A densely-packed oven may take longer to cure parts, but the difference is more than made up for by the increased number of parts being processed in each batch. Many operators fall into an inefficient rhythm of stopping and starting the oven because they don’t have enough parts staged and ready between cycles. Others dawdle while opening and closing the doors during loading/unloading, resulting in longer recovery times. 

Probably the most prevalent style of use issue is the “one curing routine fits all” approach. Running every batch (regardless of batch size, part density, part complexity, or material) at a set time, like 20 minutes, and a set temp, like 400°F, is sure to lead to curing-related finish quality issues.

A variety of colored powder coatings

You Need to Understand What the Powder is Doing

Powder curing is a thermal-chemical process that involves 4 steps:

Step 1. Flow – The powder melts, flows together, and levels out.

Step 2. Gel – The viscosity rises as chemistry activates.

Step 3. Crosslink – The polymer network forms, locking in mechanical and chemical performance.

Step 4. Cool – Once the powder coating cools, usually within a few minutes, it is safe to handle lightly. What you may not realize is that some coatings can take several hours to reach their final hardness state, so don’t assume the powder coated part is ready for use as soon as it cools. Although the coating feels hard to the touch after it has cooled, the chemical reaction isn’t always complete when the part leaves the oven. The cross-linking continues at ambient temperatures, further strengthening the polymer matrix and increasing the coating’s hardness.

IMPORTANT: Curing Time Starts Once the Part Is Up to Curing Temperature

Starting your cure time when you finish loading parts into a hot oven is one of the most common mistakes powder coaters make. When your powder rep talks about the powder’s specs or technical data sheet (TDS)—also known as a product data sheet (PDS), and mentions “12 minutes at 400°F,” he means the part needs to stay at or above 400°F for 12 minutes AFTER the part metal temperature (PMT) reaches 400°F, NOT after the oven’s internal air temperature reaches 400°F.

What Does This Mean for Your Coating Operation?

For best results, invest in a good quality temp probe system. It will include a temp probe (usually a type-K thermocouple) that connects to a handheld display or a heat-resistant data recorder. The probe is typically known as a bulb-type or contact thermocouple. It is meant to be attached (usually with tape or some type of clip) so the “bulb” or exposed metal tip is firmly touching the surface of the part. Fluke and other multimeter brands often have thermocouple attachments for their higher-end meters. You’ll probably need to get an optional extension wire so you can thread the probe wire through the oven door and attach it to the part. 

Locate the portion of the part that is farthest from the heated air discharge points in your oven. If the part profile is complex, choose a spot that is blocked from direct air impingement, as this area will usually take longer to heat up. The goal is to monitor PMT at the coolest section of the part and time how long it takes to reach the desired curing temp. This will help you establish how long it takes for the part temp to ramp up to the desired curing temperature.

DON’T rely on a cheap handheld infrared “gun.” Imagine a cone-shaped area of sensitivity extending out of the front of the IR gun, sort of like the beam of a flashlight. Most of these devices have an effective range of only a few feet, and the farther the part is from the gun, the wider the “cone” of sensitivity is. So, you aren’t getting an accurate spot reading, you’re getting an average across the sensor’s detection area. Worse, the built-in laser only gives you an idea where the center of the detection cone is located. It doesn’t have anything to do with the reading–don’t think there’s anything fancy or technologically advanced about these products. They’re notoriously unreliable, especially if you’re dealing with a reflective surface or one that is heavily textured. Curved surfaces also frequently result in faulty readings. Don’t risk a lucrative project by relying on an $80 gadget. 

How Does This Impact Cure Times in a Conventional Gas-Fueled Batch Oven?

Light, thin, small parts typically need 5-10 minutes to get to curing temperature.

Heavy, thick, complex, or densely racked parts can take 10-30 minutes to reach your target curing temperature. Extremely dense & complex parts, like large industrial machine parts, can require 30-40 minutes to reach curing temps—remember, you need to consider the coolest portion of the part, not the warmest.

Your total oven dwell time = ramp-up time + dwell time at specified PMT. For a fully loaded batch oven filled with moderately heavy parts, that usually means 25-45 minutes.

How Long Should I Cure a Powder Coated Part?  What Temperature Should I Set My Oven To?

To answer these questions, you need to know what type of powder you’re working with. Here’s some typical curing schedules for popular powders, but you need to check the TDS for the exact powder you’re applying. 

If you’re using a standard polyester powder, a common scheme is to cure for 10 minutes with a PMT of 400°. With higher durability polyesters, the temp range is about the same, but the dwell time can be up to 15 minutes. With low-temp polyesters, the curing temperature is lower, usually 325°–350°F, but the dwell time is longer, typically 20-25 minutes.

Urethane and hybrid powders are typically cured below 400° at 375°-390°F for around 10-12 minutes. 

Epoxy powders cure at even lower temps, usually between 350°–375°F, but also normally require 10-12 minutes for best results.

How to Get Consistent Curing Results

For best results, you need to create unique curing routines (sometimes called schemes, recipes, or schedules) for parts of similar sizes, densities, and materials. We’ve already covered this in some detail above, but here’s a summary:

Use a temp probe to measure PMT. Attach the thermocouple to the slowest-to-heat section of the part.

Record ramp and dwell times. Log the time from oven entry to target PMT, then the dwell time at spec temperature.

Test your routine. Run multiple parts using the information you’ve compiled and check for a good cure.

Document your routine. Keep a simple instruction sheet for every group of similar parts. Record the oven setpoint, the expected ramp time, and the required dwell time at PMT. You can also use a sketch or written summary to describe parts/rack placement in the oven. Always include info from your QC checks.

Make good notes. Keep up with factors that can impact curing results. Are the racks extra-full, causing reduced parts spacing? Did you run a mix of aluminum and steel parts or light and heavy parts in the same batch? Did you encounter an oven shut-down or did someone fail to latch the doors properly? This information can help you keep track of potential issues. More sophisticated automated systems often include data logging controls, but you can do good job of keeping track of potential problems by using a notebook or marker board.

How to Avoid Common Powder Coating “Style of Use” Mistakes

We talked about style of use earlier, but let’s look at some of the most common operator errors that lead to curing defects.

Changing powders without re-profiling → Different formulations = different curing behaviors. Don’t guess, run a test.

Never running a test to begin with → Run a test with every new part family or load condition before you cure several batches. Don’t guess, run a test.

Failing to understand the performance of your oven → Work with a factory technician to map the oven or run performance tests with a Datapaq or similar data logger. Avoid hanging parts in areas with known temp extremes or understand how hotter or cooler areas will impact curing.

Ignoring part temp (PMT) → Measure your part temperature with a thermocouple during testing; don’t rely on the oven’s air temp display as a guide until you’ve at least done basic testing. Remember, most ovens use a single temp probe to measure the air temperature at only one point inside the oven. There can be significant temperature variations throughout the oven interior, especially with less expensive ovens.

Getting antsy and starting dwell time too early → Start dwell timing once you get the right PMT, not the moment you see the air temp return to setpoint. 

Mixing heavy and light parts or steel and aluminum parts without a plan → Your curing routine needs to fully cure the most time-consuming parts without overcuring parts that reach curing temps more quickly. If you can’t safely do this, split the loads into separate batches.

Carelessly loading the oven → Tight spacing between parts restricts airflow, so you’ll probably need more time to get an acceptable cure with a heavily loaded rack. You may also need to change your curing routine if you’ve loaded the oven more densely than usual. DON’T block the intake for the heat system’s air recirculation fan(s) as this can significantly retard performance and/or cause shut-downs due to excessive heater output temps. If you load parts too closely to the oven’s hot air discharge ducts, you risk having powder blown off.

A Question We Get Asked All the Time: Can I Go Faster?

The answer is often YES, but it comes at a cost. 

You need to stay within the powder supplier’s published guidelines, but most powders can be cured effectively using a handful of different temperature and dwell time combinations. These combos are based on a time vs. temperature equivalency. Typically, a shorter dwell time can be used if the curing temp (PMT) is higher. Higher oven temperatures can cause oven components to degrade more quickly, recovery times after opening and closing doors increase, plus you’ll burn more gas to reach those temperatures. Risks include gloss or color shifts and incomplete crosslinking if your curing routine is outside the validated range. Alternatively, you can select longer dwell times at slightly lower PMTs. Benefits to this strategy include energy savings and gentler heat on sensitive substrates. You should always confirm TDS guidelines and verify performance with data logging and QC tests before changing production recipes.

How to Confirm You’re Getting a Good Cure

Although you can use test panels (sometimes called witness panels or sample coupons) to confirm curing performance once you’ve established an effective curing routine, the best way to know you’re getting good curing results is to test a few parts that are then discarded or recoated. 

You can use a data-logging system like an Elcometer or Datapaq to record actual PMT throughout the cycle and compare performance with the TDS guidelines. This is one of the best ways to ensure proper curing.

One of the fastest and least expensive ways to check for adhesion is to perform a cross-hatch test. This confirms that the finish has adequate bonding strength and hasn’t been undercured.

You can also perform a solvent rub test, which is usually done with MEK. This is a fast way to check the coating for crosslink performance (and confirm solvent resistance).

You can learn more about QC testing by clicking here. 

Some coaters like to make sure the powder they’re using doesn’t have any defects and confirm there wasn’t an unseen hiccup with the curing process. They do this by including test panels with every load and checking them for discoloration and other finish flaws before bending them to see if there is unusual delamination or cracking of the coating.

The 6 Most Expensive Mistakes Powder Coaters Make

Even successful powder coaters still make costly mistakes. What we’ve found when consulting with our customers is that it’s not always the obvious things—like buying the wrong powder or chemistry—that hurt the most in the long run. Often, it’s the combination of overlooked daily habits, process flaws, and poor planning that drain profitability.

Here are the six most expensive mistakes powder coaters make, along with insights on how to fix them:

1. Rework Due to Poor Surface Preparation

One of the most common (and costly) mistakes in powder coating is inadequate surface preparation. Skipping steps or doing a poor job of cleaning, blasting, or pretreating parts leads to poor adhesion and inconsistent finishes. These defects often aren’t noticed until after curing, sometimes requiring a full redo of the work. This can more than double the labor and materials costs for the job.

Cost impact: A single batch of improperly prepped parts can wipe out the profit of a full day’s work. Multiply that across multiple orders per month and you’re potentially looking at tens of thousands of dollars or more in lost margin.

Solution: If your employees encounter defects, make sure they’re corrected before the parts leave your facility. Invest in training your workforce, enforce process controls, and standardize your inspection routines. To help prevent defects, every part needs to be properly prepped and ready for coating before powder ever touches it. Learn more here.

2. Neglecting Equipment Maintenance

Skipping routine maintenance to save time or money is short-sighted. When powder coating or finishing equipment fails, you lose time, delay orders, and increase coating defects. You risk losing important customers and wasting your labor budget. Unless your operators are diligent and observant, you may not realize something is a problem until it’s too late—after a full batch has to be reworked. If the oven shuts down mid-cycle, a powder gun’s electrostatics don’t work properly, or the spray wand is applying pretreatment chemistry that isn’t properly titrated, you could be dealing with a very costly but preventable failure.

A related issue is when the finishing line manager doesn’t require routine filter changes. Clogged exhaust filters reduce the performance of your spray booths and can slow your coaters down because the overspray doesn’t move away from the part the way it should. It’s harder for them to observe coverage as they coat, which can lead to defects. If the filters become damaged, overspray can accumulate on the exhaust fan and inside the exhaust unit, creating problems in the future. 

Cost impact: A single breakdown can easily cost over $1,000 in emergency repairs and lost productivity. Cumulative equipment neglect can cost $50,000 or more per year in downtime and inefficiency.

Solution: Implement a preventative maintenance schedule and train your team to constantly look for and successfully detect issues. Most equipment manufacturers, like Reliant Finishing Systems, provide free maintenance guides. Keep critical spare parts on hand and document all downtime and repair or maintenance activity.

3. Poor Workflow Planning

It’s tempting to bounce between projects to please customers, but the chaos can kill throughput and inflate your costs. Inefficient scheduling can result in excessive color changes, wasted booth or oven time, idle employees, and disorganized workflow. Color changes and powder switches, especially in manual batch shop settings, are a huge hidden cost. Without a standardized procedure, you risk cross-contamination, rejected finishes, increased labor costs, and excessive powder waste.

Along the same lines, if you are jumping between selling work and performing work, you can inject idle time and inefficiencies that clobber profitability. Your powder coating equipment only makes you money when it’s working.

Cost impact: Wasting even one hour per day due to unnecessary change-overs or disorganized workflow can cost over $20,000 annually in added labor, inefficient powder use, and missed productivity.

Solution: Numerous case studies have shown that disciplined scheduling is far more profitable than reactive flexibility. When possible, group similar jobs by color, substrate, and cure time. Use software or whiteboard systems to batch your work efficiently or develop a hanging strategy to maximize line density on a conveyorized system. Develop and document lean change-over practices. Invest in fast booth cleaning routines, blow-off guns, and color-change training. Consider buying extra hose sets for your powder guns to reduce downtime between powder changes. If you’re operating at a moderate volume, you may benefit from having one or more spare guns so operators can have them loaded with powder and ready to go when it’s time to swap colors or textures. In high-volume shops, consider dedicated booths for popular colors.

4. Poor Powder Management and Inventory Control

Powder that’s improperly stored, expired, or misused (wrong curing temperature, poor application technique, etc.) leads to waste, rework, and dissatisfied customers. Letting inventory levels get too high ties up cash, while running out of popular powders causes delays.

Cost impact: Wasted powder alone can add up to $5,000–$10,000 annually in a medium-sized shop, not including powder lost due to excessive overspray. The costs are much greater if you consider jobs that were lost due to delays and/or discounts that had to be given to offset late deliveries. These numbers don’t take into account the drag on your operating budget if you’re stocking a large inventory of rarely used powders or chemistries.

Solution: Use a FIFO (first-in, first-out) inventory system to keep supplies fresh, maintain detailed logs of powder usage by job, and store materials in a climate-controlled area. Make sure operators are trained on powder acclimation procedures, especially when operating in hot, humid climates. Be diligent about proper chemistry use and titration. Work closely with powder and chemistry suppliers to get smaller, just-in-time orders if needed.

5. Underquoting Complex Jobs

Many coaters lose money by not accurately pricing jobs, especially when dealing with custom work, large parts, or odd geometries. Whether it’s underestimating masking labor, not understanding how to get access to all areas of the part that need coating (this is often related to not determining how the parts will be racked or hung from conveyor BEFORE quoting), failing to include handling and packaging costs, or not accounting for multiple powder change-overs, inaccurate quoting almost always results in lost profit or even outright losses.

Cost impact: Underpricing just one major job a month by 20% can equate to $20,000–$40,000 or more per year in unrealized profit.

Solution: Track time and material usage carefully on all job types, build a quoting tool that includes true costs, and train sales staff not to “guestimate.” It’s better to invest more energy on the front side to get your pricing right than to spend it on the back side dealing with issues that weren’t properly accounted for.

6. Failing to Track Job Profitability

Many powder coaters don’t analyze which jobs, part types, or customers are the most profitable. Without fairly accurate job costing, you may be filling your schedule with unprofitable work just to stay busy. Busy isn’t the same as profitable. 

Cost impact: If 20% of your jobs are close to break-even or worse, your shop is likely working harder than it needs to with nothing to show for it. Depending on the size of your coating operation, this can mean you are doing tens or even hundreds of thousands of dollars in work without making a dime on it.

Solution: Set up simple job costing reports for every completed order. Track labor hours, materials, overhead allocation, and profit per job. Over time, you’ll learn which jobs to pursue, and which ones to avoid or price differently. If you have no shortage of potential work, consider implementing a more sophisticated yield management strategy to maximize profitability. 

Conclusion

Powder coating is a competitive industry with rising performance expectations as the powder finishing process becomes better understood and more widely used by customers. If you’re not watching for hidden money leaks, they can quickly drain your bottom line. 

The good news? Each of these seven expensive mistakes can be corrected with discipline, attention to detail, consistent performance, and a data-driven mindset. Profit isn’t about the money you take in–it’s about the money you keep. Plug the leaks, and your shop will run smoother, smarter, and more profitably.

Maximizing Powder Coating First-Pass Transfer Efficiency: 8 Essential Factors

0

by Michael Schuerer

President, Reliant Finishing Systems

Why First-Pass Transfer Efficiency Matters

In professional powder coating operations, achieving high first-pass transfer efficiency (FPTE) is essential for cost reduction, throughput improvement, and quality control. FPTE refers to the percentage of powder that successfully adheres to the part during initial application compared to the total amount sprayed. Poor transfer efficiency results in wasted material, reduced throughput, and inconsistent finishes.

This article discusses industrial powder coating best practices and FPTE using traditional manual or automated powder spraying techniques and professional electrostatic guns. We’re assuming that the parts have been properly prepared for coating via mechanical and/or chemical pretreatment. We’re also taking into consideration that coating is being done in a production environment where quality must be balanced with throughput, rather than in a laboratory or classroom setting. 

This guide outlines eight critical factors that influence transfer efficiency and offers practical tips for fab shops, powder coating businesses, and manufacturers that finish their own products. Let’s start with site-related factors that the average business owner or finishing line manager can address without blowing the bank, then we’ll cover powder booth designs for efficiency, powder specifications, and powder gun optimization tips.

1. Set Powder Coating Performance Standards

You need to start by having realistic expectations, well-documented performance goals, and a system to log the results you’re actually getting. 

Typical electrostatic powder coating transfer efficiencies range from about 30% to as high as 95%. “Real world” transfer efficiencies above 80%-85% are rare. Higher numbers almost always involve coating processes that use powder reclamation, where spent powder is captured and blended with virgin powder for re-use. In those cases, the percentage cited is actually a measurement of utilization rate rather than transfer efficiency. 

There are plenty of issues that can reduce transfer efficiency. If you consider 60% to 70% as being a reasonable baseline for efficiency in a production environment, you’ll likely encounter parts that can’t be coated to that efficiency level, no matter what you do.

Parts that are quite small are generally not likely to be coated as efficiently as larger parts. Even with “wrap” due to electrostatic attraction, the powder cloud is often so much larger than the part that waste is inevitable. Part geometry can also contribute to efficiency challenges. Complex shapes with recesses and sharp angles can be difficult to coat evenly, reducing FPTE. Parts that have a substantial number of holes or intricate open spaces, such as mesh trash cans, can also be less efficient to coat. 

As a general rule, challenging parts like small brackets with complex profiles or wire goods like compact wire baskets may result in a FPTE of only 30%-40%. At the other end of the spectrum, it’s reasonable to expect a FPTE of 70%-80% when coating large flat panels. 

2. Train Operators to Improve Powder Coating Efficiency

FPTE improvements often come from better people and processes—not just better equipment or supplies. Even top-quality powder coating equipment can underperform without skilled operators. 

Your coaters need to operate at a professional level and perform consistently. You need to be realistic about their skills, regardless of their past experience. It’s important that coaters are trained about equipment operation and application techniques, and they need to understand the importance of basics like gun-to-part distance. It’s not uncommon for us to visit established powder coating operations where coaters don’t understand the gun settings or have misconceptions about how electrostatic coating works.

Formal training and testing is the solution. This can include refresher courses, as well as technical training at on-boarding. You may want to implement an in-house mentoring program, where more skilled and experienced operators help newer employees.

You also need to make sure your personnel are actively invested in the coating process. They must remain focused. This may require adjustments to policies and procedures. Coaters who learn to perform consistently and remain observant day-in and day-out can be a huge asset and help reduce powder waste. You’ll want to make sure your management team is responsive to internal concerns about issues with your powder coating application processes.

3. Prioritize Preventive Maintenance of Powder Coating Equipment

Maintaining your coating equipment does more than just extend its life and minimize downtime, it ensures that the equipment operates at its best. To maximize transfer efficiency, you’ll need to be organized and proactive. It’s critical to implement maintenance checklists for end-of-shift, daily, and weekly maintenance, as well as setting timelines for more involved maintenance needs. Once you’ve set a maintenance schedule, stick to it. 

You need to routinely inspect and replace wear parts like gun hoses and nozzles. It’s also important to change booth filters at intervals suggested by the filter providers instead of waiting until your booth’s performance is compromised. 

John Thomason, VP of Reliant Finishing Systems, notes, “If you try to stretch out the life of your intake or exhaust filters, they can get clogged to the point that the booth’s airflow is no longer adequate. This reduces visibility in the booth while spraying, leading to less efficient coating. If you’re dealing with worn out or damaged cartridge filters, they can produce airborne fibers that lead to finish defects because the pulses of compressed air that clean the filters can end up blowing fibers onto the part. Another area where maintenance can make a huge difference is grounding. Whether you’re using rolling racks or conveyor, hooks that are caked with baked-on powder don’t have adequate conductivity. The same goes for racks with powder build-up on the casters, or on the areas where hooks contact the racks, or where ground straps are attached to the racks. Keeping these areas free of powder build-up is critical. The better the ground, the more powder you’ll have on the part.”

👑Pro Tip: We’ve seen great results when companies install one or more supplemental ground rods as close to their booths as practical and then use heavy gauge cable to connect the grounding rod(s) to the conveyor, to rolling racks, or directly to parts (when practical). We suggest using 8’ copper rods with 12-gauge or heavier ground straps and high-quality clamps or fittings.  

4. Increase Racking Efficiency & Line Density

This is a simple concept. By positioning more parts in front of the gun(s) at any given time, you’ll boost FPTE. 

Many shops are familiar with using software that “nests” parts before cutting them out so they can get the largest number of parts from a sheet of material. Visualize your parts as they hang from a rack or as they pass by on the conveyor. Try to create a flat wall of nested parts whenever practical and minimize the gaps between parts by fine tuning your racking approach. If you have a manual booth, remember to leave enough room to allow for easy access by your coaters. 

If you’re working with automated guns, you have a few advantages, especially if you’re coating similarly sized and shaped parts. This advantage is even greater if the parts are relatively flat and/or aren’t particularly complex. Automated coating systems use sensors to detect the presence of incoming parts. Some systems also use sensors to detect part size and attitude and adjust gun performance accordingly. These higher-end systems adjust voltage, airflow, and spray timing dynamically to improve FPTE. 

❌Avoid This: Some multi-gun systems have one or more arrays of guns that require adjustment to gun location and attitude whenever changing from one part type to another. Companies with poor coating practices frequently crank up the output of the guns to avoid the need for fine adjustment (or to support unrealistically high throughput requirements). This approach is probably the most wasteful of all powder coating techniques we’ve encountered and provides consistently poor FPTE.

5. Assess Your Powder Spray Booths: How Powder Booth Design Impacts First-Pass Transfer Efficiency

Start by making sure your booths are adequately sized, appropriately designed and constructed, and in good repair. Most powder booths are built from steel panels that have been galvanized, aluminized, or powder coated to prevent surface corrosion. These booths are considerably less expensive than models built from specialty materials like stainless steel, poly, or engineered plastics. The more expensive booths are usually encountered when dealing with coating systems that utilize automated guns and have integrated powder reclamation capabilities. 

The booth’s construction material doesn’t typically have a significant impact on transfer efficiency, but its lighting, filtration, and airflow can.

Lighting 

For manual coating or touch-up, OSHA and other organizations indicate that a coating enclosure needs about 100 to 150 foot-candles of light at the object being coated in order to reach an ideal atmosphere from production efficiency standpoints. Too much light or poor light quality can detract from this environment. 

Almost all professional quality powder booths now have LED lighting that provides broad spectrum illumination much like natural sunlight. The concept is to match a slightly cloudy summer day where the light seems a little hazy and diffused. Blasting the parts with lights–the “more light is better light” approach–is scientifically unsound. Properly lit powder booths help coaters identify defects before the parts are moved to the oven to be cured. Coaters can also achieve more uniform coverage and better FPTE. 

Filtration

Filtration systems are essential for maintaining clean air in the booth and capturing overspray, but they also impact spray performance in more subtle ways that can affect FPTE. 

Intake filters remove airborne debris from incoming air, usually at the point where it enters the enclosure. They are typically located in the doors of the booth but may also be in the ceiling or side walls. 

In many businesses, particularly job shops, the powder booth may not have doors. These are known as open-faced booths. They rely on exhaust airflow to keep the spent powder from escaping. It can be challenging to minimize finish contamination with these booths unless shop maintenance practices are well managed. 

Exhaust filters remove powder overspray and airborne debris from outgoing air, usually at the point where it is exhausted from the enclosure. They are typically located in the rear wall of the booth but may also be in the floor or side walls. 

Many batch powder booths currently in operation use a series of disposable filters, typically made of polyester, to capture overspray as the air is exhausted. These booths are often open-faced and may be quite large in size. As mentioned previously, routinely servicing these filters is critical to FPTE. 

In addition to these rather simple booths, there are powder booths available with much more sophisticated filtration systems. The most popular of which rely on cartridge filters with pleated media to capture overspray efficiently. The filters are mounted inside exhaust units. The number and placement of these units determines how airflow is pulled through the booth. Poorly located or badly maintained exhaust units can create areas of turbulent airflow, which disrupt the powder path and reduce deposition on parts, compromising FPTE.

Automatic pulsed-air cleaning systems keep cartridge filters from clogging with powder buildup. If filters become restricted, airflow through the booth may increase in unwanted areas, pulling powder away from parts or altering the direction of spray. Regular maintenance ensures consistent airflow and better FPTE. 

High-quality filtration also enables effective recovery and reuse of spent powder. While this doesn’t directly improve first-pass efficiency, it improves overall material utilization—especially when FPTE isn’t optimal.

Airflow

For best coating results, powder booth airflow must be reasonably balanced. The goal is to contain the powder overspray and make the booth atmosphere ideal for spraying operations. The airflow in a powder booth isn’t typically as forceful as in a wet paint booth because if the exhaust airflow is too high, it can pull powder away from the part before it adheres, significantly reducing FPTE. If airflow is too low, sprayed powder may hang in the air and obscure the work piece from the coater.

A well-designed powder booth improves FPTE by slowly guiding overspray towards the filters without distorting the charged powder cloud while it surrounds the work piece. 

Cross-draft booths—where the air in the booth moves parallel to the ground and is drawn into filters mounted on the rear wall–are popular for batch coating. These are also sometimes known as cross-flow booths. 

The side-draft booth is a variant where the air moves side-to-side instead of front-to-back.

⚠️ Beware: Some powder booths, particularly less expensive ones, are no more than economy-oriented wet paint booths that have had extra filters strapped to them. In the most obvious cases, there will be a small section of exhaust duct that has a cube-shaped box covered in filters mounted on top of it. In a wet paint application, this box would not be included, and the exhaust would be ducted to the outside atmosphere instead. Not only does this filtration method not work very well, the interior of the booth typically has filters that go all the way to the ceiling which can be costly to replace(adding this since it seems to provide a more direct reason why this is bad otherwise I’d just remove the line altogether). Because the characteristics of airborne powder are different than those of wet paint overspray, this design is suboptimal and may reduce FPTE.

Semi-downdraft booths–where air primarily moves parallel to the ground, but is also drawn downward into filters located near the floor–are also very popular and generally well-suited to most powder coating situations. 

Downdraft booths–where air travels vertically downward into filters–are sometimes used, especially with automated guns and conveyorized systems, because the overspray can be captured directly below the parts.

6. Optimize Powder Particle Size Distribution

Powder coating media is made up of finely ground solid particles, typically ranging in size from 10-120 microns (µm), depending on the formulation. Most standard powders fall within the 25-75 micron range, which is ideal for general-purpose electrostatic spray applications.

The size of these particles affects how well they fluidize, how efficiently they become electrostatically charged, and how easily they travel through the powder hose and spray gun. It also determines how they behave in the air and how likely they are to stick to the part.

How Particle Size Affects FPTE:

  • Small particles (under 25 microns) charge easily and provide excellent surface smoothness but can be more difficult to fluidize and are prone to being carried away in airflow, resulting in lower transfer efficiency and more overspray.
  • Large particles (over 75 microns) may not charge effectively or adhere well, leading to poor coverage and uneven film thickness. They can also clog guns and hoses if not handled properly.
  • The sweet spot for maximum FPTE involves powders with a narrow, controlled particle size distribution, typically in the 30 to 60 micron range. These particles strike a good balance between fluidization, chargeability, and adhesion.

While average particle size is important, the distribution—the range and consistency of particle sizes within the batch—is just as crucial. A tight particle distribution ensures predictable flow, consistent electrostatic behavior, and uniform film build.

Powders with wide particle distributions may fluidize inconsistently and behave unpredictably in the spray pattern. As an example, if a batch contains both extremely fine and very coarse particles, the finer ones may float past the part, while the heavier ones fall out of the cloud before reaching the surface.

To optimize FPTE, use powder from reputable suppliers who offer quality-controlled particle size ranges with minimal variation. You may want to use sieves or classifiers to remove oversized or agglomerated particles, especially when dealing with reclaimed powder.

👑Pro Tip: For automated lines, or any situation where you are spraying a high volume of powder and consistently working with parts of similar size and shape, consider custom powder formulations with tighter tolerances to match your specific part geometry and application setup. The efficiency improvement can outpace the increased cost, resulting in a lower applied cost. 

7. Manage Powder Gun Electrical Settings

Improving your FPTE requires correct tuning of voltage, current, and grounding.

Adjusting Voltage (kV)

Voltage, expressed in kilovolts (kV), is the most important setting for creating an electrostatic field. Most professional guns can be adjusted between 10 and 100 kV. For flat panels or large, simple surface areas, a setting around 80–90 kV is typical. Lower settings are common with more complex parts. 

Higher settings increase the attraction between the powder and the part, but higher voltage isn’t always better. If voltage is too high, it can cause “back ionization,” creating rough texture and poor finish quality. It can also repel powder from recessed or intricate areas due to strong electrostatic forces (known as the Faraday cage effect).

To improve FPTE:

  • Use higher voltage for flat parts and larger parts with simple surfaces.
  • Drop voltage to 40–60 kV for recessed or detailed parts to help powder penetrate corners.
  • When using higher voltage settings, watch for issues related to back ionization (typically the formation of small “craters” in the coating).
  • If using modern professional guns, tweak pre-sets to get optimal results.

Adjusting Current (μA)

Current settings, expressed in microamperes (μA), control how much charge is transferred to the powder. Professional guns limit the current to avoid overcharging, which can cause powder to repel rather than attract. If the current is too high, powder can bounce off the part rather than sticking to it. You may see uneven buildup or have difficulty coating edges.

Modern guns have adaptive μA limiters but may allow manual settings. The current load increases as the gun gets closer to the part being sprayed. On a gun with an adjustable current limiter, when the current load reaches the set limit, the kV will quickly decrease. This helps prevent problems from too much voltage, especially when the gun is too close to the part.

How-To: Experienced coaters usually start with a moderate μA limit and observe the cloud behavior. Lower μA settings are better for coating parts with deep recesses or tight corners. They may also work well when dealing with very small parts.

Check Grounding–Again

As we stated earlier, good grounding is essential. The part must be electrically grounded so that it attracts the charged powder. Poor grounding drastically reduces FPTE and can cause powder to build up unevenly or fall off before curing. Ensure the rack or hanger is clean and makes strong metal-to-metal contact with the part. Confirm the ground path is continuous and uncompromised.

👑Pro Tip: A megohmmeter can help test for ground integrity (target is under 1 megohm). Although often used to check the quality of wiring insulation, these tools may be worth the investment if you are having doubts about your grounding scheme. 

Match Settings to Part Geometry

Don’t “set it and forget it.” There’s not really a one-size-fits-all setting. Self-adjusting guns typically have fine tuning adjustments. For best results, use preset programs on advanced guns or create custom recipes for different part types. Adjust your gun(s) in real time while watching powder behavior and coverage patterns.

8. Control Powder Gun Airflow and Powder Delivery 

Efficient powder coating requires a careful balance between powder output and airflow. If either factor is misadjusted, it can lead to problems. Properly tuning your gun(s) for both ensures optimized FPTE, improved finish quality, and a cleaner working environment.

Powder Output refers to the amount of powder delivered through the gun. This is controlled by the powder regulator, typically an easy-to-find knob that allows rapid adjustment of powder output. Too much powder can overwhelm the electrostatic charge and result in excessive overspray, while too little powder may leave thin or uneven coverage, especially in recessed areas. The goal is to maintain just enough powder flow to coat the part efficiently without generating excessive waste.

Airflow involves both atomizing air and flow air. Atomizing air disperses the powder into a fine airborne mist, while flow air carries it through the hose and into the electrostatic field around the part. Insufficient airflow can cause poor powder dispersion, clumping, or sputtering. On the other hand, excessive airflow may disrupt the powder cloud or even blow powder off the part before it adheres.

How-To: To find the optimal balance, most coaters start by adjusting the powder output to a moderate level and then fine-tuning the airflow to create a soft, consistent powder cloud. Watch how the powder deposits on the part—uniform cloud coverage that gently wraps around corners and recesses is ideal. It’s especially important to avoid setting airflow so high that it reduces the dwell time of powder near the part or exacerbates Faraday cage issues in tight areas. 

If the powder cloud fills your booth to the point you can’t easily see through it during operation, you’re likely using too much air. You may also be using too much powder.  On the other side of the coin, if it looks like you’re getting more powder on the floor than you are on the parts, you’re likely using too much powder, and you may also be using too much air and blowing powder off the parts.

👑Pro Tip: Buy good quality powders that have a low percentage of inert material, then work directly with your powder suppliers to get advice and hands-on training about how to improve FPTE with their specific products. 

Unlock Greater Powder Coating Efficiency

By considering these eight factors, you’ll reduce powder waste, shorten production cycles, improve finish quality & minimize rework, plus enjoy secondary benefits like increased equipment life!

Improving First-Pass Transfer Efficiency (and powder coating efficiency in general) isn’t just about reducing powder overspray. It’s about building a repeatable, cost-effective powder finishing process that delivers consistent results.

How To Get The Best Powder Coating Training For Your Business

0

Our customers frequently ask about training for their new employees who have no coating experience. Although we answer questions and provide basic hands-on guidance with new customers, we don’t routinely host training classes. Unfortunately, there aren’t many classes or trainers that we feel comfortable recommending. This article covers what to avoid when seeking powder coating training.

1. Don’t Rush It

In our opinion, the best approach is to let new employees work with senior coaters to learn all they can BEFORE you enlist a trainer or send them to classes. Without any prior coating knowledge, a new employee won’t have the experience needed to understand basic terminology or ask critical questions. When you send employees to a coating class, the instructor is going to cover a set curriculum, so the chance to get specialized help will typically only come during the Q & A sessions. If your employees don’t know what to ask, they won’t get maximum value from the class. 

2. Consider On-Site Trainers

There’s a lot to be said for having someone come to your facility and teach your employees on the equipment that they’re going to be using. This is one of the best ways to train your employees, but it comes with a risk. Unlike organizations that offer classes, trainers have almost no overhead. They don’t have to buy finishing equipment or maintain a facility. Because there is no real barrier to entering the training business, anyone who knows a bit about powder coating and isn’t afraid to hit the road can tout themselves as on-site training experts. Our advice is to check out their credentials and insist on talking directly with past students in unmonitored conversations. Don’t be afraid to ask hard questions about whether or not the training they received had value.

3. Don’t Waste Time Or Money

We also advise against classes where there isn’t a substantial amount of hands-on training that will allow your employees to improve their skills. Spending half a day taking turns using a pretreatment wand and a powder gun isn’t going to achieve much. These less-than-effective classes tend to fall into two categories: “pep rally” classes designed to generate enthusiasm about the coating business in general and classes designed for hobbyists trying to launch a backyard business.

4. Avoid Getting Hustled

Many non-academic classes are tied to companies that will offer your workers free or heavily discounted passes to attend. No established powder coating organizations or professional brands offer these types of freebie classes. Be careful or you may end up paying the bill to send your employees to nothing more than a pep rally where the instructor will use classroom time to tout the equipment or supplies they sell, followed by minimal technical training. As a general rule, stay away from training being offered by anyone trying to sell you something. Instead, consider training from a neutral party, such as an independent organization. 

5. Go Big Or Stay Home

As we mentioned above, one type of class that may flood your online search results is the “get rich in powder coating” or “start powder coating” training offered by numerous online outlets. The problem with many of these classes is that they are taught using small hobbyist equipment set-ups, so your new employee who is going to be coating spiral staircases or big industrial machine parts isn’t going to get much useful hands-on experience. It pays to get the details before you invest in powder coating training.

6. Check For Fitment

At the other end of the spectrum, some classes are so detailed and science-oriented that newcomers can easily be overwhelmed. These are usually more advanced classes and (unlike the others outlined in 3-5) have a good bit of value—they just aren’t a good fit for new coaters.

Our last bit of advice is to ask blunt questions about any training class you are considering and make sure it’s suitable for your company’s needs before you commit. Remember, you can often receive in-depth guidance from powder, paint, and chemistry vendors who want to establish or retain your business. This is also a great opportunity to establish long-term relationships with suppliers that can be beneficial to your company.

So, who do we recommend for training?

Introduction: A Fab Shop Needs Help

Recently we were contacted by a well-known fabrication shop that was having quality issues with their finishing work. They purchased a powder coating equipment package from a web outlet that sells booths and ovens for entry-level professional use. Unfortunately, they couldn’t get adequate support after the sale, so they reached out to Reliant for help. 

Using their new powder coating equipment, the company coated several steel parts that were permanently installed outdoors in a hot, humid, sunny location. After installation, they discovered that some of the parts had blemishes in the coating when viewed in bright sunlight. Within a few weeks, the finish started flaking off and there was rust underneath. 

Parts Inspection

We started by talking with them about the way they inspected their parts. We learned they did not have a dry film thickness (DFT) meter for checking coated parts. Also, they hadn’t been performing crosshatch adhesion tests or solvent rub tests. They would visually inspect finished parts for obvious cosmetic defects, but they weren’t doing anything else to confirm the thickness or integrity of the finish.

Quality Control Testing

We emphasized the need for QC which is outlined in our article about quality control testing:

Finish Defects

In addition to the coating peeling off in large flakes after the parts were installed, there was a rust problem. When they examined flaws in the coating, the metal underneath would sometimes be quite rusty and rust stains would show through at the edges of the defect. There could be two slightly different causes for this: 

  1. The initial defect was caused by anything that led to the part’s bare steel surface being exposed: inadequate powder coverage, finish damage due to rough handling, the powder not being properly cured, etc. Once the original defect occurred and the integrity of the finish was compromised, water was getting through the defect to the part’s surface and creating rust. This could cause discoloration and contribute to the edges of the defect peeling back even more. 

Because of the very large size of the flakes, the significant amount of rust, and the lack of obvious handling damage, we didn’t feel this was the cause. 

2. It seemed likely the coating wasn’t adhering properly due to rust. There was either rust forming underneath the unbroken coating due to condensation, or they were possibly coating over existing flash rust. Defects formed as the cured powder “let go” from the metal substrate and eventually cracked and peeled off in large sections. Once the coating was broken, blemishes could grow due to water intrusion just as with #1. 

This seemed to be the most likely answer based on the information they provided.

Equipment Shortcomings & Poor Pretreatment Practices

We spoke with the shop manager about their pretreatment practices. In rare cases, they had an off-site media blasting company prep badly rusted steel parts for chemical pretreatment. They sometimes used an older general-purpose pressure washer to remove dirt and grease if blasting wasn’t warranted. For large parts, they applied pretreatment chemistry with a pump-up sprayer and hosed it off. They weren’t precisely measuring chemistry titration or timing exposure once the chemical was applied.

For smaller parts, they used the inexpensive steam unit that was included with their powder coating equipment package. It was suitable for small parts and occasional use, but it wasn’t designed for big jobs or high-volume shops. It didn’t provide precise metering and didn’t have the ability to easily swap between the various chemicals the company would need to use if they wanted to consistently get professional quality results. 

Our discussion revealed they weren’t taking time to document exactly how they were pretreating different batches of parts. Making the situation worse, the operator was purposefully preparing chemistry that was overly-concentrated. We explained that mixing pretreatment chemistry “hotter” (more concentrated) doesn’t mean it will automatically work better. You should follow the guidance provided by your chemistry supplier.

We also learned they weren’t attentive to dwell times, leaving chemicals on for up to a few hours before rinsing, and sometimes not rinsing them at all. Although there are no-rinse products on the market, these are very specific chemistries and not what was being used. According to the coater, almost every part had some level of residue remaining on the surface of the part at the time it was coated. They also sometimes coated over very mild flash rust, rather than remove it. 

Once this was revealed, we were on the path to resolving the issue!

More Isn’t Always Better

The surfaces of the parts often had a powdery film on them after being chemically treated. This could seriously inhibit powder adhesion. A chalky residue appearing on a part after chemical pretreatment is usually caused by incorrect chemical concentration or pH levels (for example, the chemistry hasn’t been diluted enough), leading to too much metal attack and the formation of a powdery phosphate layer on the surface. This is sometimes referred to as “over-phosphating.” The acidic residue can also promote flash rust.

If you powder coat over metal that has a dried phosphate residue on the surface, the powder coating may not adhere properly, leading to potential peeling. The dried residue can act as a barrier between the metal surface and the powder coating, so a thorough rinse after the phosphate treatment is recommended to remove any residue and ensure optimal adhesion of the powder coating. Rinsing also helps prevent flash rust, which this company observed on some of their parts. If rinsing doesn’t remove the residue, further steps are needed to resolve the problem.

Pretreatment Basics

We talked with the company about how they should change their approach to preparing their parts for coating. First, we shared a brief article covering 3 guidelines for pretreatment:

Use Care With Iron Phosphate

Then we used this article to discuss iron phosphate pretreatment:

More Advanced Testing For Coated Parts

We shared an article about testing standards that may be required by more sophisticated customers. This helped them understand what’s common in the industry:

https://reliantfinishingsystems.com/cleaning-pretreatment-primer-part-two-meeting-standards/

Best Practices

We explained a typical approach might be to clean the part using a detergent, rinse it, use a phosphate to treat it, rinse it, and then apply a sealer or perform one or more secondary rinses. At the highest end, shops may use a pretreatment routine that has as many as 9 or more steps. 

For manual pretreatment, we typically suggest purpose-built spray wand systems from PEM or steam units from Electro-Steam (Reliant is a national level distributor for both). 

When parts are being transported by conveyor during the finishing process, a multi-stage pretreatment washer is typically the best choice if your acquisition budget allows. Reliant manufactures these and also partners with other companies that build them.

A Comprehensive Solution

Although they were having poor luck getting support from their equipment provider, we suggested they reach out to the chemical supplier they were working with to see if they would help get things back on track. Unfortunately, their chemistry was also being supplied by the online vendor who sold them their equipment. This long-distance “5-gallon bucket at a time” approach saved money, but it meant they weren’t interacting with a chemical company rep that could provide hands-on support at their facility or send parts back to a company laboratory for testing. We suggested they should interview at least two or three local/regional representatives from established companies like DuBois, PPG, Chemetall, Calvary, and Coral in order to start a productive relationship with a company that would be a good fit for their future growth.

We also suggested they consider a PEM spray wand system. Reliant partners with PEM to provide everything from spray wands to large multi-stage automated wash tunnels. PEM offers multiple products based on their P-300 system. This system has a base unit that includes an adjustable pump and an LP or natural gas fueled heater with temperature control. The base unit is connected to wands that let you switch between chemicals by simply swapping to a different spray wand. This eliminates the need for purging the system or swapping the pick-up between sources. Each wand has its own metering insert, so you can set each wand for the appropriate amount of chemistry or detergent dilution. This system also allows you to choose whether each stage is heated or not.

We recommended buying a DFT tester, performing crosshatch and solvent rub tests, and starting a documentation process where they log information about every coating job they perform. We encouraged them to start a more interactive relationship with their powder supplier, perform testing to gain a better understanding of their oven’s performance, and establish coating and curing routines that would get the best results with the powders they were using.

Conclusion

Although the coating equipment they bought had shortcomings, especially the powder curing oven and steam pretreatment unit, the company’s finish defects were primarily related to the way they were preparing their parts for powder coating. The lack of adequate technical assistance from their coating system and chemical provider contributed to the problems they encountered. 

Based on our input, the company immediately revised their pretreatment practices, developed a plan to acquire better pretreatment equipment, and began reaching out to established brand-name chemical companies.
