ABSTRACT:
The accumulations of molten lead which correspond to the lugs and frames of molded starter battery plates can be caused to solidify at the same rate as the much thinner grids of the plates by providing a mold having inserts made from a material whose thermal conductivity is higher than that of the base material of the mold in the regions of the mold which are used to form the lugs and frames, provided these inserts are disposed as close as possible to a system of cooling channels. The ratio of the thermal conductivity of the material from which the inserts are made to the thermal conductivity of the base material of the mold should approximate the ratio of the material accumulations on the lugs and frames to that on the rest of the grid.
