다이슬라이드식 사출성형을 통한 플라스틱 밀봉용기 성형에 관한 연구

Die slide injection as eco-friendly manufacturing process marvelously reduces the cost and time in processing plastic sealed container because they can simplify the conventional process through eliminating additional process. However, the high-speed injection of resin-seal-molding in the die slide injection invokes undesired shape defects, which can be extremely minimized by die correction or process parameter control. In this study, the process parameters of the injection molding are optimized by using CAE analysis and Taguchi method. The process variables are optimized by using the L₁?(or L?)orthogonal array and smaller-the-better characteristics of the Taguchi method. In addition, according to two kind of polypropylene and one kind of polyethylene, results of experiments were compared by measuring as the analyzing experiments. Consequently, the applicability of the Die slide injection was confirmed.
