PVD, one advanced technology used in prototyping industry

Physical Vapor Deposition (PVD) refers to the film preparation technology of material deposition on the plated work-piece by physical method under vacuum condition. PVD technology is mainly divided into three categories: vacuum evaporation coating, vacuum sputtering coating and vacuum ion coating. But at this stage, PVD coating cannot replace chemical plating, and in addition to the stainless steel surface can be directly PVD coating, in many other materials on the work-piece for PVD coating, they need to be electroplated Cr (chromium).Hand plate factory PVD coating and traditional chemical plating is the same point, both belong to the category of surface treatment, are through a certain way to make a material covered on the surface of another material. The difference between the two is that the PVD coating film and the work-piece surface adhesion is greater, the hardness of the film layer is higher, wear resistance and corrosion resistance is better, the film performance is more stable; PVD coating can be plated on a wider variety of film layer, can be plated out of a variety of film color is more beautiful; PVD coating does not produce toxic or polluting substances.
