Simulation and Experimental Study of Vibration Injection Filling Based on Disk-shaped Mold

Abstract

In this article, the vibration injection mold-filling is investigated by combining computer simulation with experiments. The material of the object is high density polyethylene (HDPE). For some of the experiments, a center-gated disk-shaped mold is designed independently using a cooperation with hydraulic pressure dynamic injection machine. The profiles of speed, pressure and temperature field can be obtained during vibration injection mold-filling. The results of the experiments and theories tend to be consistent, showing that the vibration field accelerates melt filling, enhances the properties of the molten fluid and reduces pressure drop during mold-filling, and the shear action impacted by the vibration field heats polymer melt.
