Powder coating services
Powder coating is the electrostatic application of organic powder to metal parts requiring protective or decorative coating. The powder is cured by heating or baking, resulting in a hard, continuous coating.
The process begins with pretreatment — surface preparation of the substrate. Each part is cleaned, removing grease, dirt and anything else that might interfere with the painting process. This usually consists of cleaning the metal surface and etching it to prepare the surface to bond well with the powder during the curing process that follows.
Once completely dry, the part is ready to have powder applied using either fluidized-bed or spray techniques. The powder is electrically charged as it is applied to the part, giving each particle of the powder a negative charge. The part being powder coated is electrically grounded as a means of attracting and attaching the powder to the part’s surface. This electrostatic attraction is a key requirement of the process, aiding the coating evenness and the speed of applying the coating. The result is a uniform coating of dry powder clinging to the part.
After the part is coated with powder, it’s moved into a curing oven. Once there, the powder gels, flows and cures to produce a smooth, durable powder-coat finish. During the curing process, a chemical reaction cross-linking between the particles of powder takes place. It is at this point that the part can be removed from the oven, cooled in ambient air and put into service.
