Application of mold filling simulation to die casting processes

Recently the authors find many reports on mold filling simulation and the related subjects. Using a general use computer code FLOW-3D, they research the practical application of mold filling simulation to die casting processes. The paper describes the result of this application. They compare the results of a water model experiment for die castings with that of the simulation. They determine the analysis conditions which cause the same flow patterns. To estimate the casting defects from the conditions, they compare the casting by a test die with that of the simulation. The application of the analysis model to a casting of air conditioner compressor proves practically useful by measuring amount of gases contained in the die castings.
