PVD (Physical Vapor Deposition)
Typical failures on the surface of plastic molds include abrasive wear, scratch and corrosion. PVD coatings protect the surface of the mold surface from such damages while improving filling and de-moulding. For your reference, we have provided the table below with a list of coatings for specific applications.
|Coating||Composition||Microhardness HV50 Range||Service T °C||Deposition T °C||Color||Functions|
|D-ARC||CR/α-C:H||2000÷2500||350||200||Grey/Black||Release, Surface protection|
|TiN||TiN||2000÷2400||400||400||Gold||Release, Surface protection|
|CRN||CRN||1600÷2000||700||400||Silver||Release, Surface protection|
