Cooling Simulation of External Gas-Assisted Injection Molding
This paper present a cooling simulation method for External Gas-assisted Injection Molding (EGAIM). To simulate the cooling process of EGAIM, a Finite Element Method model with heat transfer processing with isotropic materials containing inner heat source was established, and pressure was loaded on the interface of mold and part as gas packing pressure. The simulation was used to explore the effect of process parameters on the quality of an example with different thickness ribs with ANSYS. The results showed the method is feasible and reliable.
