ABSTRACT:
An apparatus for making a battery grid is characterized by a molding die for molding a lead conductor with a plastics frame. The die has runners or channels defining the grid structure, and valves are positioned at the intersections of the channels for the lead conductor and the channels for the plastics frame. The valves are actuable to selectively block the channels for the plastics frame from the channels for the conductor. In the use of the die to form a battery grid, with the valves actuated to block the channels for plastics from the channels for lead, molten lead is injected into the channels therefor and is confined therein to form the conductor. The valves are then actuated to unblock the channels for plastics and hardenable plastics are injected therein to form the plastics frame, with the frame being molded around the conductor at intersections therewith.
