Powder Coating

Powder Coating Services

Pyramid Fab and Finish has provided quality sheet metal fabrication and finishing services for almost 50 years. In support of these services, we offer in-house, conveyorized powder coating. Using advanced coating materials such as high-quality epoxy, polyester, epoxy/polyester hybrid, TGIC, and urethane powder coatings. The process produces a durable and robust finish that will stand up to some of the harshest environmental and operating conditions. Whether flat, glossy, or textured, our powder coated finishes impart durability, flexibility, and insulating properties to components while providing protection against heat, impact, and ultraviolet (UV) radiation.

What Is Powder Coating?

Powder coating is an advanced, dry finishing process. It uses free-flowing (fluidized) powders that are first applied to the surface electrostatically, heated to the melting point, and hardened into an even layer. The powders are available in many colors and formulations that can create various surface textures. This broad availability and versatility make the process ideal for creating protective and decorative finishes on a wide range of parts and products. As powder coating makes up a large percentage of the overall industrial finishing market, it is likely that many of the components you encounter on a day-to-day basis are powder coated.

Our Powder Coating Process

Powder coating materials are made from polymer resin systems combined with curative, leveling agents, flow modifiers, pigments, and other additives, all of which help improve the functional and aesthetic quality of the finish. These ingredients are melted, mixed, cooled, and ground to form a powder. Once the powder is ready, it can be used in powder coating operations.

At Pyramid Fab and Finish, our state-of-the-art facility features a fully automated line that is capable of handling small to very large components. Our powder coating process follows these steps:

  1. Pretreatment. The parts to be powder coated undergo a five-stage pretreatment process that includes multi-metal acidic cleaning and reverse osmosis.
  2. Drying and heating. The clean and treated parts are sent through a dedicated dry-off oven to improve powder adhesion.
  3. Powder coating application. The dried parts pass through the first paint booth, where 24 robotic spray guns apply the coating material to their surfaces. Once the coating material is applied, the coated parts pass through a custom-designed Faraday cage booth to ensure complete coverage.
  4. Curing. The coated parts then enter a dedicated cure oven, which provides precise temperature control depending on the powder.
  5. Inspection. Once each lot completes the coating and curing stages, it undergoes careful inspection and testing. Tests include gloss meter, scratch adhesion, chemical rub, and impact resistance.

Advantages of Powder Coating

Spray paint product powder coating

There are many advantages to using powder coating over other finishing processes, such as:

  • Greater durability. Compared to liquid paints, powder coatings are more durable. They have greater resistance to chips, scratches, fading, and wear.
  • Better eco-friendliness. Powder coating materials do not contain solvents, meaning no dangerous chemicals are released into the atmosphere.
  • Shorter processing times. Compared to liquid paints, powder coatings dry/cure much faster, which saves time and space during processing operations.
  • Cleaner operations. Powders are much cleaner to apply than wet paints. Additionally, it is much easier and faster to clean powder spray booths than wet paint booths.
