Ceramic Plating Machine/PVD Vacuum Coating Machine For Gold Jewelry A PVD coating machine utilizes physical vapor deposition technology to apply thin, durable coatings on various substrates without chemical reactions. The process takes place in a vacuum chamber where a solid material, known as the target, is vaporized through methods such as sputtering or evaporation. These vaporized particles then travel through the vacuum and condense onto the workpiece, forming a uniform
