PURPOSE: A hydroforming device is provided to save maintenance and production costs and to be installed in a small place. CONSTITUTION: A hydroforming device contains an upper and a lower die(41,42) having a settlement portion(40) for a pipe or tube shaped material(30); a sealing member(43) sealing the settlement portion; and a forming device forming the material with pressure by sealing the settlement portion and directly inserting into the material at once. The forming device consists of an igniter(50) sealing the settlement portion from the upper and the lower die and inserting into the material; an installation groove(61) for the igniter; an injector(60) having plural injecting holes(62) communicated with the installation groove; a high temperature and high pressure generator generating high temperature and high pressure gas in the injector; and a controller(70) controlling the high temperature and high pressure generator. The high temperature and high pressure generator comprises a gunpowder device(500) installed in plural grooves(520) of the igniter and controlled by the controller.
