What is PVD coating ?

The PVD is such coating technology that forms a few micron hard films

on tools. The hardness of PVD is higher than tungsten carbide super-hard

material. In comparison with hard-chromium, intruding too, the PVD film is

much harder. The only few microns film is improves anti-wear property

dramatically.

Because the thickness is a few microns, we can avoid the dimension

changing problems except the application that require very precise accuracy.

The PVD coating makes the product surface smooth and get more color

option to upgrade product quality.  PVD coating improves the ability of

resistance to abrasion, more gorgeous color. And this technology is

corresponding international environmental protection technology, so the PVD

coating won’t be harmful for the healthy.
