IMPROVEMENTS in PRESSURE FERROUS CASTINGS Influencing their Future Use 450153
PRESSURE casting is any casting method in which the mold cavity is filled by pouring metal into it under pressure from sources other than gravity.
This pressure may be exerted by means of centrifugal force obtained by rotating the mold, or by exerting air pressure on the molten bath from which the mold cavity is being filled.
Mr. Jeter describes the highlights of the development and improvements of the centrifugal casting field, and particularly the improvements in steel centrifugal castings in the past several years. He also describes briefly the air-pressure casting method.
