【Abstract】 Numerical analysis of the flow of thin-wall parts during filling stage of injection molding is investigated by using a hybrid FEM/FDM method here. The temperature, velocity and pressure distribution in the flow field are calculated. And combined with the experiment results, some useful results are obtained. Theory foundation is offered for the control mechanism of filling stage. The results have instructive meanings in mold design and controlling injection technology.更多还原
