PRESSURE CASTING APPARATUS AND PRESSURE CASTING METHOD

摘要

PROBLEM TO BE SOLVED: To improve quality of casting products formed by pressure casting process.;SOLUTION: When a filling rate of molten metal for a die cavity reaches a predetermined filling rate selected from a range from 93% to 98% by high-speed injection of molten metal, a plunger is deceleratingly controlled to boost a pressurizing force of the molten metal gradually.;COPYRIGHT: (C)2008,JPO&INPIT
