Cathode plate edge protector systems formed by secondary and tertiary molding processes, in which fluid plastic is molded around and/or introduced into previously manufactured plastic edge protectors. A U-shaped edge protector system is formed by bevel-cutting abutting ends of edge protector strips, securing the strips in the desired configuration a molding jig, and molding corner pieces around the abutting ends. The system is then removed from the jig and slip-installed over the two sides and the bottom edge of a cathode plate. In an optional tertiary molding process, fluid plastic may be introduced into the remaining void between the edge protector system and the cathode plate. Another edge protector system is formed by mounting edge protector strips on opposing side edges of a cathode plate, damming the open ends, and introducing fluid plastic in the contained voids between the strips and the cathode plate.
