摘要 Co-injection molding has been developed for decades. However, due to too many factors which can affect its processing, it is very difficult to obtain good quality of co-injected products all the time. One of the major challenges is that the prediction and management of the advancement of core material is very difficult. In this study, both CAE simulation (Moldex3D) and experimental methods have been applied to investigate the advancement distance of core material in co-injection molding based on the standard tensile bar (ASTM D638 TYPE V) system. Specifically, the flow behavior of the core material has been predicted numerically and verified experimentally through short shot testing, and skin/core ratio effect testing. Moreover, based on the optimized skin core ratio, the major factors to influence of the advancement of core materials have been conducted. Finally, to quantify the advancement of the core material in co-injection molding, both simulation prediction and experimental observation were performed. Results showed that the advancement of the core material is strongly proportional to the core ratio in co-injection molding system. Moreover, the flow rate and the different skin/core material arrangement also can influence the advancement of the core material.
