SQUEEZE CASTING

Abstract

Squeeze casting is a method of producing large thin-waled castings by (1) the formation of a thin metal crust on the wall of the mold halves, and (2) the formation of the casting by joining the two crusts together and squeezing out the excess metal. The squeeze-casting machine consists of 2 jaws, a sationary jaw carrying a mold plate and sand core, and a movable jaw wih mold plate, carrying a die and side lips to prevent runout of the metal. The stationay jaw is supported by a bracket, and the movable jaw is hinged to the base frame. Hydrodynamic properties of squeeze casting promote the removal of gases and solid impurities from the metl, thu proviing higher strength and ductility of the casing walls than is the case for other csting methods. Squeeze-cast panels have a smooth, clean surface and high dimensional accuracy, so that they require little machining. (Author)
