Anodic Oxidation, Aluminum or Aluminum Alloy products for the anode in the electrolyte solution for power handling, the use of electrolysis to the surface of the alumina film process, known as the anodized aluminum and aluminum alloy. After anodizing, the aluminum surface can generate a few microns or a few hundred microns of oxide film. Than the natural oxide film of aluminum, corrosion resistance, abrasion resistance and decoration has significantly improved and enhanced.

The main Aluminum Die Casting Surface Finishing purposes are:
(1) improve the wear-resistant parts, corrosion resistance and weather resistance to corrosion.
(2) oxidation of a transparent film, coloring made from a variety of color film.
(3) as a capacitor dielectric film.
(4) binding with the organic coating. For coating the bottom.
(5) for the bottom of plating

Electrophoretic Paint (electrophoretic coating), also known as the electrophoretic coating, electrophoresis is becoming increasingly popular with the defects of conventional spray constantly emerge. Electrophoretic paint industry began to replace old ones, electrophoresis paint from the anode to the cathode electrophoretic paint, electrophoretic paint from a single component to the two-component electrophoretic paint, electrophoretic paint development also contributed to the development of the electrophoretic coating, so that more Products to use the spray technology but the use of electrophoresis.
