냉각채널에 따른 Nozzle 제품의 휨 변형 특성 연구

Plastic injection processes comprise injection, packing, cooling, ejection and process/part quality control applications. Plastic injection provides a number of advantages over the weight reduction, assembly simplification and high productivity. In this study FE analysis was performed with MoldFlow2009 to optimize flow characteristic. With optimized conditions, cooling channel was designed and cool analysis was performed. Warpage characteristic at various cooling conditions was analyzed. The results show that warpage can be successfully reduced by appropriate control of cooling channel and cooling temperature.
