Claim 6:
7. A method for manufacturing a forged product from a forging material by forging between an upper die and a lower die facing each other inside a housing, the method comprising the steps of:
charging the forging material into the housing having an integrally formed housing body through a charging port of the housing body; and
forging the forging material between the upper and lower dies by:
(i) heating the upper and lower dies with a heating mechanism under a condition in which the charging port of the housing body is closed by a door, the heating mechanism being disposed inside the housing so as to partially or entirely face outer peripheral side surfaces of the upper and lower die;
(ii) moving the upper and lower dies relatively in a facing direction of the upper and lower dies, the upper die and the lower die being inserted through an upper die passage port and a lower die passage port opened in the housing body, respectively;
(iii) moving an entirety of the housing in the die facing direction; and
(iv) moving the heating mechanism in the facing direction relatively with respect to at least one of the upper die and the lower die moving relatively.
