Theory of Spray Filling for Aluminum Alloy Die Casting The theory of spray filling in aluminum alloy die casting was proposed by Frommer in 1932 based on practical experience in zinc alloy die casting and through a large number of experiments. Frommel conducted an analysis based on the ideal liquid flow and believed that the filling process of liquid metal follows the laws of fluid mechanics, and there are friction and vortex phenomena. Through experiments, it is believed that when molten metal enters the mold cavity from the inner gate, the shape of the cross-section of the inner gate shoots towards the opposite mold wall away from the gate. After impact, some of the metal accumulates and produces splashes. The metal disorderly merges with the subsequent mainstream, causing eddy currents, while the other part of the metal splashes in all directions and flows back along the mold wall. The counter pressure generated by the metal accumulation causes friction on the mold wall, The metal f…
