Anodizing

Anodizing on aluminum frequently used in different application. Anodizing is great surface treatment, which is good for tight tolerance parts. And help to resist corrosion and increase surface hardness.

The perfect of anodizing is that you can choose different color for a variety of visual request.

Paint

Painting significant resistance to varieties of environmental concerns, which is an important form in the visual arts. a great painting work that makes your products in high level. The most interesting things are that you can choose any color that you prefer or tell us Pantone code.

Etching & Printing

There are many ways to provide custom printing and etching text and logo on your parts.

If you want to make the most precise and permanent marks, we suggest using etching & silkscreen. Follow is an example for reference.
