Abstract

Presently, engineering molding technology has made significant progress, making it possible to produce workpieces with modern tools and machines. Prototypes and unique work can also be done faster. An engineering simulation program is necessary to produce, and precision molding is one of the manufacturing processes that can produce complex workpieces or require detail without a machine. By the way, there are a lot of defects that occur in casting workpieces due to shrinkage. In this study, the casting designer is a simulation program that is necessary to investigate the flow behavior of molten metal for a track shoe part. To increase work efficiency, develop production, and reduce costs, including accurately analyzing trends in production. The flow behavior simulation result showed that the imperfections of the casting were minimal in the second condition without damaging the workpiece, displaying a shrinkage of 0.039 percent using a molten metal casting time of 23 seconds, and a molten metal casting velocity of 40 meters per second. While the third condition, it is the least shrinkage, representing 0.023 percent. The imperfections of the casting cannot be used.
