摘要：
The object of the present invention is to provide a casting method capable of simultaneously attaining the shortening of cycle time and the improvement in casting quality.The pressure allowing the molten metal level to go up to the positions of from P0 to P4 is applied to the molten metal within a molten metal reservoir 1. Then, the pressure of P4 is maintained for a predetermined time. During this time, the molten metal which comes into contact with an upper die 4 is cooled earlier than the molten metal being in contact with another die. Through this cooling the molten metal shrinks. However, since the pressure of P4 is maintained, the molten metal is supplied from the lower side to a shrunk portion, so as not to cause shrinkage cavity or underfill.
