Abstract

The cell poles of an electric battery, which have already been cast on a fully assembled plate group which is fixed in proper position for mounting in a holding box, are provided with a plastic coating using a dual injection mold which matches the predetermined distance between the poles. After the two mold halves are closed over the poles, a plastic melt is injected into cavities corresponding to the poles, which plastic is at the same time prevented from escaping from the mold by a gasket at the base of each cell pole, and a movable slide at the forwardmost end of each cell pole.
