Optimal Design of Mold Layout and Packing Pressure for Automobile TCU Connector Cover Based on Injection Molding Analysis and Desirability Function Method

Abstract

In this study, the optimal design of the multi-cavity mold layout and packing pressure for the automobileTCU connector cover is determined based on the injection molding analysis and the desirability functionmethod for multi-characteristic optimization. The design characteristics to be optimized are the warpage andsink marks of the product, the scrap of the feed system, and the clamping force. The optimal design isdetermined by performing injection molding analysis and desirability analysis for design alternatives definedby a complete combination of five mold layouts and six-level packing pressure. The optimal design showsthat the desirability values for individual characteristics are quite high and balanced, and the resulting valuesof individual characteristics are satisfactorily low.
