| Abstract: | The process of the gas-assisted injection molding(GAIM) were analyzed,and the key technological requires were stated in this paper.The implementation principle of GAIM numerical analysis was investigated,which based on the analysis of polymer melt flow and gas penetration physical model.The CAE analysis of gas-assisted injection was made on a T-type bracket by MPI/Gas module.The simulation result showed the gas penetration effect in different process.The rational process parameters were confirmed. |
