A Study on the Filling Balance of Elastomer TPVs in Multi-Cavity Injection Mold

다수 캐비티 금형에서 엘라스토머 수지의 균형충전도 연구

Almost all injection molds have multi-cavity, which are designed with geometrically balanced runner system in order to made filling balance between cavity to cavity during injection molding. However, filling imbalance has been existed in the geometrically balanced runner system. In this study, we made an experiment and surveyed that are filling balanced variation according to molding condition with thermoplastic vulcanizate (TPV). Also, we conducted experiments in order to know the influence of filling balance for runner core pin (RC pin).
