A sprue system, for use in a pressure casting machine, such as a machine for hot chamber die casting, or for producing castings from a thixotropic alloy, or a cold chamber die casting machine, is provided, which includes a plurality of sprue dies which form a sprue housing, or bush, through which a sprue region extends longitudinally between inlet and outlet ends of the housing or bush. The sprue dies are relatively movable laterally with respect to the longitudinal extent of the sprue region, between an advanced position in which the sprue dies form the housing or bush and a retracted relative position.
