In order to unify the standard for the manufacture of tensile test bars for LPDC process, a new die for LPDC process was designed. Based on the simulation results of the casting processes of the test bar die, the location and types of casting defects were analyzed, being helpful to select more suitable casting process parameters for the test bar. In this paper, the LPDC process was applied with suitable parameters based on the simulation results. The rationality of the mold design was verified. Finally, based on the simulation results, the melt filling process inside the test bar mold and the temperature field change at different points were analyzed, and the rationality of the mold design was verified.
