Abstract

A mould is equipped beneath its base with a molten metal reservoir in communication with the mould by means of a number of injection tubes through which metal is injected by applying compressed air onto the surface of the bath of metal. In this addn., the reservoir is covered with a sealed lid, fixed by its upper face to the base of the mould leaving a thermal insulation zone between the reservoir and the mould in which cooling liq. may be circulated. The reservoir is treated by electrical resistance heaters integral with its walls and the main geed duct has, at the level of the reservoir, a tube which enters the metl almost reaching the bottom of the reservoir, to receive the melt when the compressed air is blown in. Used esp. for casting aluminium alloys. The process can be automated producing castings at regular intervals.
