성형장치는, 금속파이프재료를 팽창시켜, 파이프부 및 플랜지부를 갖는 금속파이프를 성형하는 성형장치로서, 서로 쌍이 되어, 파이프부를 성형하기 위한 파이프성형면, 및 플랜지부를 성형하기 위한 플랜지성형면을 갖는 제1 금형 및 제2 금형과, 제1 금형 및 제2 금형 중 적어도 일방을 구동하는 구동부와, 구동부를 제어하는 제어부를 구비하고, 제1 금형의 플랜지성형면 및 제2 금형의 플랜지성형면 중 적어도 일방에는, 형폐쇄 시에 타방의 플랜지성형면과 당접하지 않는 돌출량의 돌출부가 형성되며, 제어부는, 돌출부에서 플랜지부를 압압함으로써, 플랜지부에 부분적으로 두께가 얇아진 박육부를 형성하도록, 구동부를 제어한다. A forming device which expands a metal pipe material to form a metal pipe having a pipe portion and a flange portion includes a first die and a second die, which are paired with each other and include pipe forming surfaces for formation of the pipe portion and flange forming surfaces for formation of the flange portion, a drive unit that drives at least one of the first die and the second die, and a controller that controls the drive unit, in which, on at least one of the flange forming surface of the first die and the flange forming surface of the second die, a protrusion portion that protrudes by an amount not to abut against the other flange forming surface when the dies are closed is formed and the controller controls the drive unit such that a thin wall portion at which a thickness of the flange portion becomes partially small is formed at the flange portion by the protrusion portion pressing the flange portion.
