Abstract

An electroplating barrel holds items to be electroplated while permitting the passage of electroplating solution into and out of the barrel. The solution enters the barrel through small perforations in the sidewalls of the barrel and then is circulated by the rotation of the barrel in an electroplating bath. In this invention the circulation of the electroplating solution, and thus the efficiency of the electroplating process, is increased by directing the flow of the electroplating solution into and out of the barrel through the use of a support rib structure defining perforated sections in the shape of parallelograms. Also, within those parallelogram shaped sections, the utilization of parallel, elongated openings defined by support segments further encourages the multidirectional flow of electroplating solution. The access doors, through the use of an improved locking mechanism also utilize an identical rib support structure with elongated openings.
