A. Have you thought of shot peening with steel ball media?

A. Mr. Wen,
How are you producing your parts now? More specifically, how are you producing the parabolic surface and imparting brightness? If you are using a stamping die or a mold it may be a matter of giving the tool the orange peel effect. If the finish has to be applied to the already formed parts and the aluminum wall is thin, then blasting will distort it beyond acceptable limits.
