The STI DryCoat system is based on plasma technology (plasma-nitriding, PVD, PACVD) and is the logical supplement to the WetCoat system which is based on a galvanizing process; with this additional technology, STI Group offers the full range of services in surface technology. The STI DryCoat system is used where components are exposed to extremely hard conditions: extreme wear, abrasion or a tendency to cold welding, and in order to reduce friction loss between moving parts. Typical applications include tools for processing thick and highstrength materials and molds for diecast and pla-stic tools.
