Abstract: An electroplating barrel of polygon shape has interlocked panels, and each panel has an outer grid portion defining relatively large rectangular openings, and an integrally formed inner portion including a perforated plate contiguous with the outer grid porton. A method is disclosed for forming the panel from polypropylene with a substantial portion of chopped glass fibers, both the inner and outer panel portions being integrally formed with one another in an injection molding machine.

Abstract: Polygon shaped barrels of different size can be readily assembled from conventional end plates of appropriate diameter, and conventional support members connect the end plates to one another to define rectangular openings. Panels, which can be readily cut to size along predetermined lines are placed in these openings. The largest barrel size utilizes panels which need not be cut, whereas proportionately smaller barrels are made up from panels cut to predetermined, somewhat smaller, sizes. Each panel includes an outer portion having relatively wide generally longitudinally extending ribs, and intersecting cross ribs, to define relatively large rectangular openings. The inner portion of each panel has smaller openings defined by partitions molded integrally to this one-piece, "one-size" panel.
