Anti-adhesion treatment of steel molds for use in rubber-, silicon rubber, thermoplastic- or thermoset injection molding, first nitrides or nitrates then adds chromium nitride layers

The surface is first nitrided (or nitrated). Formation of epsilon- and gamma iron nitrides contributes to surface hardening and conditioning for the next process. This comprises multilayer application of a closed, sealed chromium nitride layer. Plasma nitriding, laser nitriding or salt-bath nitridin...
