Chromium/nitrogen coating treatment using sputtering technology. It is particularly excellent in releasability, and can prolong the life of resin molds and powder molding molds. In addition, due to the low temperature treatment, almost no strain or dimensional change occurs in the base material. No harmful substances will be produced, and it is a pollution-free treatment.

The ion-plated coating has a dense structure, no pinholes, no bubbles, and a uniform thickness. Even the facets and grooves can be plated uniformly without the formation of metal bumps. Parts such as threads can also be plated. Since this process method can also repair defects such as tiny cracks and pits on the surface of the workpiece, it can effectively improve the surface quality and physical and mechanical properties of the plated parts. Fatigue tests show that if handled properly, the fatigue life of the workpiece can be 20% to 30% higher than before plating.
