The STI DryCoat system based on plasma technology (plasma nitriding, PVD, PACVD) is the logical complement to the galvanically based WetCoat system - and thus makes STI Group a full-range supplier in surface technology. The STI DryCoat system is used when maximum stress is to be placed on the components:  Against extreme wear, abrasion or the tendency to cold welding as well as a targeted reduction of friction losses between moving components. Typical applications are tools for processing thick and high-strength materials as well as moulds for die-casting and plastic tools.
