摘要：
Based on the development of the multi-fluid cavity filling flow mechanism in the co-injection molding, general Hele-Shaw model and Volume-of-Fluid technique to establish the theoretical model for numerical simulation to describe the cavity filling process in co-injection molding are used, and a stable effective numerical solution algorithm for solving the theoretical model is presented. The numerical simulation of the effect of material parameters and molding process parameters on the co-injection molding is implemented, and the relation between those parameters and the patterns of the layer interface is established. The results of a case study of numerical simulation have a good agreement with the experimental results.
