摘要：
In this paper, 3D simulation of mold filling for high-density polyethylene in the injection molding process using ANSYS-CFX is conducted. In addition, injection molding experiments involving deliberate short-shots done for various percentages of the optimum dosage to enable for melt front tracking were performed. Comparison between simulation and experimental results showed reasonable agreement with regard to the shape of melt front. The locations of the melt front obtained from the experiment were observed to be slightly ahead of the locations predicted by the simulation with discrepancy being attributed to the nature of the injection molding experiments.
