The cause and effect of chromium plating on die fittings.

The surface of the mold parts is the one part that must be dealt with in the process of die making. The serv** life of die accessories is also very important. The surface treatment of mold parts is mainly in physical processing mode. Chemical treatment, chemical and physical **bination processing and mechanical treatment. The purpose is to improve the wear resistance, corrosion resistance, friction coefficient and fatigue properties of the surface.

Chromium plating is also a way of surface treatment of mold parts. The chrome-plated layer has a high hardness and can prolong the serv** life of the workpiece. Coating is thin, bright beautiful, as the outermost layers of the multi-layer plating, usually for protection, for some of the stainless steel material bending or deep drawing, can more effectively prevent the surface strain, can improve the mold surface is smooth and bright, corrosion resistant, high temperature resistant, wear resistant, rust prevention and so on. Is a kind of environmental protection processing technology, with the development of science and technology and environmental protection idea more and more strong, the use scope of chrome-plated technology is more and more tube.
