Durable Finishes for Production Work
Powder coating provides a durable, uniform finish for products that need to withstand handling, weather and everyday use. It is well suited to high-volume production and a wide range of sizes, shapes and configurations.
How Powder Coating Works
Powder coating applies a dry powder made of resin and pigment to a prepared surface. The coating is then heated until it melts, flows together and cures into a continuous film.
The process includes surface preparation, masking, electrostatic application, oven curing and inspection. Each step affects the final finish, so each one is controlled.
Our Standard Sequence
-
Surface Preparation
Cleaning, degreasing and, when required, blasting or chemical pretreatment to prepare the surface for adhesion
-
Masking
Protecting threads, bearing surfaces, ground points and mating faces from unwanted coating.
-
Electrostatic Application
Applying powder to the specified film thickness with controlled gun placement and product orientation.
-
Cure
Bringing the product to the powder manufacturer’s specified metal temperature and holding it there long enough to fully cure.
-
Inspection and Packaging
Checking film thickness, adhesion and appearance, then packaging the finished work for shipment.
Where Powder Coating Fits
Durability
A properly prepared and cured powder finish provides strong resistance to impact, abrasion and chipping.
Corrosion Protection
With the right pretreatment, powder coating provides consistent corrosion protection. For demanding environments, it can be applied over an e-coat primer.
Consistent Film Build
Controlled application and curing produce repeatable film thickness and appearance across production runs.
Low Solvent Emissions
Powder contains little to no solvent, which means little to no VOC emissions from the coating itself.
Material Efficiency
Overspray can be reclaimed in many applications, reducing material waste.
Color and Texture
Powder is available in a wide range of colors, gloss levels, textures and metallic finishes.
Batch and Conveyorized Lines
We match the line to the work. Conveyorized systems are suited to repeat production and consistent cycle times. Batch booths handle large, heavy or unusual configurations that cannot run on a conveyor.
That flexibility helps us support both established programs and changing production requirements, with masking, plugging, e-coat primer, assembly and packaging available when the job calls for them.
- Conveyorized lines for high-volume production runs
- Batch booths for oversized and heavy weldments
- Powder over e-coat primer for maximum corrosion protection
- Masking, plugging and threaded-feature protection
- Assembly and packaging on the same site
What We Coat
Powder is specified across almost everything we touch, most heavily on parts that live outdoors or take physical abuse in service.
- Agricultural and construction equipment components
- Truck bodies, toolboxes and hardware
- Frames, brackets and structural weldments
- Enclosures, cabinets and guarding
- Material handling and storage products
