xPro – L4

Vacuum Hard Coating System With New PDA III*-Technology and HiParc-Technology (optional)

The xPro – L4 is the most advanced industrial large size vacuum coating system, which includes the PDA*-technology. It is specifically designed for the deposition of high performance metallurgical coatings, such as AlCrSiN, AlTiSiN, AlCrN, AlTiN, CrN, TiC,N, TiN and many others. Such coatings are evaporated by arc onto a variety of cutting tools, dies and moulds, components and consumer products for wear, erosion and  corrosion protection as well as tribological purposes. The xPro – L4 is also in a “pulsed” high power version as xPro – L4H available (HiParc**), where the technology and power supply package enables faster depositon rates, shorter cycle times and significantly improved target utilisation.
