Vacuum metalizing involves heating the coating metal to a boiling point in a vacuum chamber. The condensation deposits the metal onto the substrate’s surface. Resistance heating, electron beam or plasma heating is used to vaporize the coating metal. After several steps, the parts receive a primer coat which consists of a glossy basecoat which are then baked. A reflective film metal is applied and finished with a lacquer or vinyl topcoat. This final coating provides a shade of color and a protective layer for the metal.
