Multiple layers can be applied to create a thicker coating and the typical thickness varies from approximately 18 μm up to 72 μm. Bead blasting is used mainly for visual purposes. I have found that I get the best finishes when I have all my cuts go the same direction. Anodizing (Type III) adds a wear and corrosion resistant ceramic layer to the surface of the part. This series is widely used in various kinds of plastic cup for filling and sealing.It can automatically finish the process of filling,sealing,cutting,printin. It requires though closer process control compared to type II anodizing (higher current density and constant solution temperature near 0oC), so the cost is higher. If an aluminum machined part goes straight to anodizing, it is likely that some machine marks or scratches will remain on the finished part's surface. Ra is a measure of the average deviation of the machined profile from the ideal surface.
