The powder coating process begins with electrostatic application. The dry powder is given a positive charge as it exits the spray gun, and the grounded metal part attracts the charged particles, pulling them into an even layer across all surfaces. This electrostatic attraction is what allows the powder to coat corners, edges, and recessed areas more uniformly than liquid spray paint can reach.
Once coated, the part enters a curing oven where temperatures reach the range needed to melt and fuse the powder particles into a continuous film. As the film cools, it hardens into a surface that is chemically bonded to the metal rather than sitting on top of it. This bond is what gives powder coating its resistance to chipping and peeling. CMV Fabrication controls oven temperature and cure time based on the coating formulation and the mass of the parts being processed.
