GATE LOCATION OPTIMIZATION IN INJECTION MOLDING BASED ON FEASIBLE SPACE

摘要

A methodology is presented in this paper to find the optimum gate location to achieve balanced flow so that a good quality part can be produced. The objective function is expressed in terms of injection pressure from the point of view of energy consumption. The coordinates of the gate location are chosen as design variables. A method is also proposed to determine the possible feasible space for gate location. The resulting optimization is solved by iterative search in the constrained space based on sequential linear programming algorithm. Examples are given to demonstrate the effect of the proposed method.
