ABSTRACT:
A capacitor closure disc unit comprises a metallic plate and a layer of rubber-elastic insulating material injection-molded around its periphery. The plate is dish shaped and includes a flat flange. The recessed central part of the plate forms a centering area which, through the help of centering projections, aids in centering the plate in a mold cavity. The outer surface of the recessed portion can be very slightly concave so that contact thereof with a planar mold section forms a circular edge seal during the injection-molding step.
