PVD coating (Physical Vapor Depsosition) is a coating technology that deposits metal or ceramic materials onto the surface of a 304 stainless steel sink in a vacuum environment through physical vaporization, evaporation, or sputtering. This process does not involve chemical reactions, resulting in a high-purity, dense, and strongly adhesive coating.

It evaporates a metal target into ions, which are then deposited onto the surface of a 304 stainless steel sink, forming a dense, strong, and corrosion-resistant metal film. This film is very thin, yet possesses extremely high strength and adhesion, significantly enhancing the appearance and performance of the 304 stainless steel sink.
