ABSTRACT:
An apparatus for the casting of metals and other materials under pressure in which the molten metal is introduced into a cylinder which is pressurized by a piston through an intervening pneumatic cushion to drive the molten metal into the mold. When the mold is filled with the metal, the piston increases the pressure further so as to maintain the pressure during solidification. Advantageously, the cylinder from which the molten metal is driven, is connected by a further cylinder to a hot chamber in which the melt is prepared, the connection between the two cylinders being at the bottom thereof and the entire assembly being mounted on a tiltable frame.
