Chemical Milling - Specialty Products

ABOUT CHEMICAL MILLING In addition to mechanically abrasive methods for patterning metal surfaces, the chemical etching process is often used. In the conventional process the metal material is first completely coated or laminated with a photosensitive resist. Then it will be UV exposed with a phototool having the desired image. The transparent parts

^ forget what it is in the mic - 6 but after alkaline etch the surface is smutty, hence you then acid etch it to get rid of that (magnesium??) and rinse then anodize, so long as the part is kept wet bettwen etch and acid etch your fine, don't let it dry, just etch, rinse acid desmutt and anodize, if you desmut with sulpheric, you only need a quick rinse prior to anodize.

Principles of the Anodizing Process - Bonnell Aluminum

Etching (Chemical Milling): Etching in caustic soda (sodium hydroxide) prepares the aluminum for anodizing by chemically removing a thin layer of aluminum. This alkaline bath gives the aluminum surface a matte appearance. Desmutting: Rinsing in an acidic solution removes unwanted surface alloy constituent particles not removed by the etching ...
