High-quality Coating Accomplished by Equipment Developed by Our Company

After 20 years of research, our company has developed a high-quality PVD coating technology that can provide smooth surface and has adhesive property.
Using TiN,TiCN,TiAlN,CrN, AlCrN coating film can help resist abrasion and corrosion of cutting tools, dies/molds, machine parts etc. And by increasing the service life of such tools, the cost can be reduced substantially. In addition, DLC Coating Process (PVD/CVD) is added to our service line, as requested by many of our customers.

• The machine developed by our company operates for 24 hours and can deliver at a flexible time
• Can handle low-volume production, partial coating, and coating removal
• Apart from processing with low temperature at 450℃, our technology also minimizes disfiguration of the base material
• Our engineers who are experienced in choosing coating based on the type of tool / pairing material will provide appropriate advice to our customers

What is PVD Coating?

Abrasion of certain materials starts at the ‘surface’, and the condition of the ‘surface’ also affects the frictions. By only hardening the ‘surface’ of the material, one can reduce the abrasion, extend the service life of the tools, dies, parts etc. And prevent damage caused by frictions by smoothening the surface. This also helps in enhancing energy efficiency too.

PVD coating is done by depositing many μｍof solid film onto the surface, and the coating’s hardness is superior to superalloy. PVD coating is exceptionally hard in comparison with other options such as hard chrome and nitriding, and can tremendously increase the material’s wear resistant property with a few μｍ of film.

The temperature during the coating procedure is controlled at 450℃. Therefore, performing heat treatment to SKH, SKD etc. will not lower the steel’s hardness.
