PURPOSE:To form efficiently parts, etc., for constituting one group by plural pieces, by executing alternately forming by a pair of different kinds of upper and lower forming dies in a press room, and carrying out a formed part from a forming die and supplying a base material to the forming die, in the outside of the press room. CONSTITUTION:A transfer device 6a is operated, an adsorbing mechanism 63 adsorbs a base material (a) from a materials stocker, and subsequently, moves along an overhead guide 60, and puts down the base material (a) to a lower die 13a on a lower side moving bolster 8a. Subsequently, the bolster 8a moves backward and a lower die clamper 10 operates, the lower die 13a is fixed to a moving passage 3, and an upper side bolster 7a is also fixed to an upper side moving passage 2. The upper side moving passage 2 descends and an inner part body 71 advances, and by intensifying the pressure of a liquid which has filled the lower die 13a, a formed part is formed. When the upper side moving passage 2 moves backward to the ascending limit, the clampers 9, 10 function, the bolsters 8a, 8b execute a cross movement in the upper and lower sides, and an soon as a formed upper die 12a is fed out to the outside of a press room, the upper die to be used enters into the room. Simultaneously, a lower die 13b to which a base material has been supplied enters.
