CONSTITUTION:A treating body 17 is loaded by a cargo gear 16 into a cylinder body 3 of a high pressure vessel 2. Then, a truck 6 and a press frame 9 are moved by an actuator 7 for the truck as far as a position corresponding to the cylinder body 3 for the high pressure vessel 2, an upper cover body 4 is lowered by an upper cover body actuator 12 to close the upper opening of the cylinder body 3 of the high pressure vessel 2. Then, a pressure-receiving plate 14 is loaded by an actuator 15 for the pressure-receiving plate between an upper holding part 10 of the press frame 9 and an upper cover body 4. Thereafter, the high pressure hydraulic medium is supplied by a hydraulic medium pressurizer 19 into the high pressure vessel 2 and the treating body 17 is molded by high isotropic pressure.
