PVD (physical vapor deposition) thin-film coating is a process in which a solid material, often a metal, is vaporized in a vacuum and deposited, atom-by-atom, onto the surface of a part. The PVD process forms a thin, bonded, metal or metal-ceramic layer on the surface that greatly improves the appearance, durability, and/or function of a part or product. The deposition process can be easily customized to change the color, durability, or other characteristics of a coating.
PVD coating enables us to produce stainless steel MIM parts with graceful, beautiful colors. The process onto a stainless steel surface provides an abrasion resistant coating that is up to 10 times that of normal stainless steel substrate. This is superior color coating that outlasts any other known coloring process. Semi-permanent in both color and luster and highly resistant to corrosion and abrasion are characteristics of our MIM products. It also well withstands very strong acid rain and pollutants. It is far better than other exterior finishes in inflammability, resistance to chemicals and economic effects. Our product wins a high reputation for its outstanding quality and diverse applications. These MIM products are popular among those who pursue elegance of the consumer electronics and greatly welcome for various applications.
