Anodizing Equipment

Anodizing is the process of increasing the thickness of the naturally occurring oxide layer on the surface of metal materials through electrolytic passivation. Anodizing improves the material’s  corrosion resistance and can improve its dielectric properties and aesthetic appearance. Numerous metals can be anodized through essentially the same process, including aluminum, titanium, magnesium, zinc, and tantalum.

Because it is a specialized process, anodizing requires specialized equipment. Perhaps the most important piece of equipment in the anodizing process is the rectifier. Anodizing rectifiers provide the electrical voltage required for high current density coatings. These rectifiers are available in numerous configurations and power levels, generally ranging from 100 to 6000 amps or more.

Most anodizing processes also utilize a digital controller to regulate the electrical output of the rectifier. Precisely controlled voltage is necessary to ensure the creation of consistent, uniform coatings on treated metal products. Many digital voltage controllers for anodizing applications can be controlled via PC interface.
