Surface treatment of zinc alloy cover :electrophoresis

It is used for stainless steel, aluminum alloy die casting, zinc alloy die casting, etc. it can make the products present various colors, keep the metallic luster, enhance the surface performance and have better corrosion resistance.


Process flow: pretreatment → electrophoresis → drying


Advantage:


1. Rich color. 2. Without metal texture, it can cooperate with sand blasting, polishing, wire drawing, etc. 3. Processing in liquid environment can realize the surface treatment of complex structure.

4. Mature technology and mass production.


Disadvantages:


The ability of concealing defects is general, and the pre-treatment of die-casting parts by electrophoresis is required to be high.
