Abstract
PURPOSE: To obtain a product which is superior in pressure resistance and mechanical properties by filling molten metal by pressure into cavities, and performing local pressurizing of the 1st stage at the point of the time when the part of small wall thickness has half solidified in a place where the wall thickness is large and that of the final stage at the point of the time when the part of large wall thickness has half solidified.
CONSTITUTION: Molten metal is filled by pressure into cavities by a main plunger 7, and the 1st stage of pressurizing is accomplished by a plunger 5 for local pressurizing provided in a part 3 of the largest wall thickness where the molten metal solidifies last, at the point of the time when a thick walled part 3' of small thickness of the product where it solidifies early. Next, the pressurizing of the final stage is accomplished while the part 3 of large wall thickness solidifying last is in a half solidified state. This may be provided dividedly by providing local pressurizing of an intermediate stage between the 1st stage and the final stage of local pressurizing or continuously.
