Theory of Full Wall Thickness Filling in Aluminum Alloy Die casting
The theory of full wall thickness filling in Aluminum Alloy Die Casting was developed by Brandt in 1937 using aluminum alloy to press into an experimental die casting mold. The test mold has internal gates with different thicknesses (0.5~2mm) and rectangular cross-section cavities with different thicknesses. The ratio of the cross-sectional area of the internal gate to the cross-sectional area of the cavity is 0.1~0.6. Brandt believed that when molten metal enters the mold cavity through the inner gate, it flows from the gate to fill the cavity thickness from the back to the front, without generating eddy currents, and the gas in the mold cavity can be fully discharged; It is also believed that regardless of the ratio of the cross-sectional area of the inner gate to the cross-sectional area of the mold cavity, the filling morphology is still "full wall thickness.".
