Product name:

Introduction to anodic oxidation:

Anodic oxidation is a kind of material protection technology for metal materials to form oxide film on the surface by anodic current applied externally in electrolyte solution.

Product usage:

Metal materials or products after the surface anodized treatment, its corrosion resistance, hardness, wear resistance, insulation, heat resistance and so on have greatly improved.Therefore, anodic oxidation technology has been widely used in the construction industry, aviation and aerospace industry, electrical and electronic industry, food industry, chemical and pharmaceutical industry, transportation and other fields.

Process flow:

Oil removal → alkali washing → acid washing → polishing → anodic oxidation → washing → coloring → sealing → drying
