Abstract

With the continuous advancement of the aviation and aerospace industry, higher requirements are desired for the structure and size of casting parts, e.g., lightweight, holistic, and precision. In line with this development trend, the demand for precision forming of complex thin-walled casting parts is getting stronger and stronger. Defects, such as porosity, cold shut, and misrun for thin-walled casting parts, are easy to form during the filling process with a fast cooling rate that cannot guarantee the fluidity and feeding ability of the liquid metal. Besides, the larger Laplace force and viscous force caused by the thinner thickness of the mold cavity wall may influence the flow state of the front edge of the liquid metal during the filling process of the casting parts, which has a great impact on the precision forming of these thin-walled casting parts.
