(2) by adjusting the thickness of the flange to ensure that liquid forging straight part of the same size, to avoid precisely control the amount of casting difficulties. (3) Reverse pressure device not only to ensure the filling of liquid aluminum and the die to achieve the overall pressure to ensure that the liquid forging size and quality.
