마이크로 유전알고리즘을 이용한 사출성형품의 게이트 위치 최적화

Abstract

A design problem was formulated to minimize the injection pressure while preventing weldlines. To solve this design problem, we integrated MAPS-3D (Mold Analysis and Plastic Solution-3Dimension), a commercial injection molding analysis CAE tool, using the file parsing method of PIAnO (Process Integration, Automation and Optimization) as a commercial PIDO (Process Integration and Design Optimization) tool. Then, we used micro GA (Genetic Algorithm) equipped in PIAnO. Using the proposed design approach, the injection pressure has been reduced compared to the initial one while satisfying the design constraint. This design result clearly shows the validity of the proposed design approach.
