To provide a casting method and a casting device for obtaining a high grade casting wherein bad influence to a molding product due to gas entrainment and the like generated to a molding article at the time when the molten metal is sequentially filled corresponding to the clearance variation of a die cavity are eliminated, in a cast molding processing of aluminum or an aluminum alloy.
A molten metal control mechanism 2 for securing the molten metal volume corresponding to the output of an electromagnetic pump 4 is provided in a metal passage pipe 3 extending from a holding furnace 1 to a cavity 9 formed between a movable die 7 and a fixed die 8. Furthermore, the laminar flow is directly filled to a mold at a turbulent flow limit velocity corresponding to the capacity per portion of the cavity 9, so that the problems generated to the molding product are solved for obtaining a high grade casting.
