Pvd Coating Equipment Metallization Vacuum Multicolor Coating Machine Plastic Sputtering Coating Plant A PVD coating machine is a sophisticated industrial system used to apply thin, durable films onto various substrates through Physical Vapor Deposition technology. The coating process occurs in a high-vacuum chamber where solid coating materials are vaporized into a plasma or gaseous state. Common vaporization techniques include sputtering, evaporation, and arc vaporization.
