Powder Coating

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.

The Process

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


  1. Surface Preparation

    Cleaning, degreasing and, when required, blasting or chemical pretreatment to prepare the surface for adhesion

  2. Masking

    Protecting threads, bearing surfaces, ground points and mating faces from unwanted coating.

  3. Electrostatic Application

    Applying powder to the specified film thickness with controlled gun placement and product orientation.

  4. Cure

    Bringing the product to the powder manufacturer’s specified metal temperature and holding it there long enough to fully cure.

  5. Inspection and Packaging

    Checking film thickness, adhesion and appearance, then packaging the finished work for shipment.

Why Specify Powder

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.

Capacity

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
Typical Work

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

“If the product will be handled, loaded or exposed to the elements, powder coating may be the right finish. Send us the print and service requirements, and we can help confirm the process.”
