Abstract

1. A method for moulding electrode grids from lead or lead alloys for electric accumulators in a casting mould, which is heated in stages during operation by the incoming melted charge and cools again therewith until the casting is released from the mould, the mould surface being provided with a porous, electrically non-conductive, protective layer which causes, however, negligible obstruction to the heat flow, characterised in that the heat which flows out from the smelting during the charging stage due to heat conduction is compensated at least partially by a heat pulse directed towards the melting charge, so that the mould contents are prevented from dropping below the solidification temperature before the end of the charging stage.
