Abstract

1. Pressure casting process in which the melt is conveyed from a melt container (1) through a duct (2) for material to a hollow chamber of a casting mould (3) under the effect of a pressure differential between the melt container (1) and the casting mould (3) and in which, after the filling of the hollow chamber (4) of the casting mould (3), the melt is cooled at additionally produced elevated pressure, with the melt being exposed in the casting mould (3) to a double-sided final pressing, characterised in that a residual space (5) of the casting mould (3) is exposed during the charging to an essentially elevated additional gas pressure as remotely applied final pressure and this increased additional gas pressure is balanced by means of a variable counter pressure on the side of the casting entry opening as casting side final pressure until there is complete charging of the casting mould.
