Anodizing barrel with pump attached

Abstract

The present invention relates to a anodizing barrel with pump attached and, more particularly to such a barrel that can be adjusted to change the desired volume subject to the processing flow when having small aluminum parts to receive an anodization treatment, enabling the anodization treatment to be performed in the same electroplating drum. When receiving pre-treatment or post-treatment, regular aluminum parts require a relatively larger space, at this time the full space of the drum is used. However, during anodization, the parts must be closely attached together. At this time, the volume of the inside space of the drum can be compressed to squeeze the aluminum workpieces against one another. Further, the motive of the drum is used to drive the pump head connected thereto, keeping electroplating solution to be well circulated through the drum.
