Abstract
In accordance with a new method of casting electrode grids for electric lead storage batteries in a mold, premature solidifying of the melt is prevented before the end of the mold filling period by an additional heating pulse applied to the melt during the mold filling process, as well as by the use of a good heat conducting mold material. The cooling down to the unmolding temperature is also accelerated. Because of the short dwell time of the lead within the mold, there simultaneously results a short machine cycling period. The separate pulse heating of the melt is preferably carried out by an induction heating apparatus, the alternating field of the inductor located within the mold walls producing heat through eddy current production within the molten molded body.
