CA 1181923

ABSTRACT OF THE DISCLOSURE: A method for pressure die casting in which a melt, under the action of a pressure or of a difference between pressures, passes from a sealed chamber with melt reservoir through a material conduit and fills a casting die, where the melt solidifies, wherein, immediately after the melt has filled the die or immediately after its solidification, there is produced above the melt within the material conduit a gas pressure of the same gaseous phase as in the sealed chamber. Before the beginning of the next subsequent casting operation, the space of the casting mould is blown-through with the gaseous phase within the material conduit pipe and the sealed chamber with the reservoir. And an apparatus to carry out this method.
