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...

Analysis of mold deformation during heat treatment During quenching and tempering of die casting molds, deformation or distortion can occur. Deformation is caused by stresses in steel, including thermal stress, structural transformation stress power. Thermal stress: The mold size will increase during heating. When heating is faster and more uneven, the size of different parts of the bow will increase inconsistently, resulting in Generating stress and deformation. The purpose of multi stage...
