Powder Coat Process


Proper metal pretreatment is required of the car, truck or motorcycle part prior to being powder coated. This pretreatment is an abrasive mechanical or chemical cleaning that must take place to prep the surface for optimized powder coating. The best results from powder coating are obtained when any rust or existing coatings are removed. The powder coat process is best suited to metal parts, weldments, and assemblies. Plastic, rubber, wood, ceramic, glass, fabric and similar non-metallics are typically not coated. Similarly, soldered parts may not withstand the curing temperatures required during the final cure baking process.

Before the powder coating application, automotive parts are hung on portable racks. Hanging the car parts ensures that the powder coat can be applied uniformly with no further handling or disturbances. Powder coating is applied in a clean containment booth to prevent contamination with dust or powders of other colors. Auto Parts are electrically grounded, and the dry powder is then sprayed using a system which electrically charges the powder particles. The charged powder is attracted by and attaches to the parts.

After the car parts are coated with dry powder, the parts (on their racks) are moved into a curing oven. As the coated car parts heat up, the powder gels and flow to produce that natural smooth powder coat finish. As decorative powder coatings reach their maximum curing temperature, a chemical reaction called cross-linking takes place. At this point, the car parts can be removed from the oven, cooled in ambient air, and be immediately put in service.
