摘要

The gas-Assisted injection molding (GAIM) process is so complicated that increasing reliance has been placed on CAE(Computer Aided Engineering)as a tool for both mold designers and process engineers. In this paper, a 3D theoretical model and numerical scheme is presented to simulate the GAIM process, in which an equal-order velocity-pressure formulation method is employed to eliminate the pressure oscillation. In addition, the whole flow field is calculated with the gas pressure as a boundary condition to obtain the gas penetration, and a 3D control volume scheme is employed to track the flow front of the melt and gas. Finally the validity of the model has been tested through case studies and experimental verification.
