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
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.
