ABSTRACT:
A plastic polehydral electroplating barrel whose rails, end heads and perforate panels are made of a mineral or fiberglass-filled thermoplastic resin, preferably fiberglass-filled polypropylene, in which the perforate panels are made of modules which when abutted edge to edge form the 30 or 36 inch panel, each module being made of a relatively thin perforate plate injection molded to contain an increased number of square drainage holes and a plurality of crossed ribs upstanding from the plate to strengthen it, those edges of the modules which engage in the rail and head grooves being reinforced to reduce load stress at the connecting points. The modules can be held in abutting relation unconnected to each other in the final barrel assembly, or can be interconnected by tongues and grooves, or can be welded together. The ribbed injection molded perforate panels can be used as inserts to make barrel halves or barrel bodies by matched metal low pressure molding.
