A differential pressure is created that causes the molten metal to fill the casting mold up to line A--A in FIG. 7, indicated by point a in FIG. 8, and the delivery pressure changes its properties. On the basis of the signal from the pressure indicator 58, the transducer 9 is actuated to open the loop 10, and a pressure of 96.10'N/ze is applied to the unfinished casting mold 3. 11 is established in the filling cavity 5.

When the piston of the cylinder 11 is moved, the inflow of molten metal from the molten J3 reservoir 1 is cut off, and the ultimate charging of the casting die 3 is carried out at high pressure. When the crystallization of the molten metal is completed, the pressure is released from the casting mold 3, and the casting part is cooled and discharged from IT'2.
