Powder coating is a process through which an electrostatic application applies a dry polymer to a base material, usually a metal such as mild steel, aluminum, or stainless steel.
Powder coating services begin by cleaning the material with chemical agents or sandblasting to remove the mill scale. Next, after being cleaned, there is a pre-treatment of a conversion coating of phosphate or chromate applied in several stages.
The powder is applied using an electrostatic or corona gun. The powder is fluidized and receives a positive charge in the system's application gun, then sprayed using compressed air to the negatively charged material. That process causes the powder to stick to the material electrostatically.
The racks are rolled into an oven, and then cured to the manufacturer's specifications. Generally, this takes 10-20 minutes at 400°F.
Our precision powder coating batch system uses a steam generator to clean and pretreat products. This helps minimize costs by reducing chemical usage, eliminates the effluents, and ensures the most even and uniform application for true quality powder coating. Our large array of coatings include varieties of surface finishes, gloss levels, and durability ratings for powder coated aluminum, powder coated steel, and much more.
