Optimization of Multiple Quality Characteristics in Conformal Cooling Channel Fabrication Utilizing Taguchi Method

Abstract— This paper points out the significancy of developing an optimization solution of designing conformation cooling system in injection molding tooling. The focus of this study is the on the model, development, and optimization which have will benefit manufacturer, especially the importance in shorten cycle time and better quality since compared with traditional cooling systems, conformal cooling can greatly reduce the warpage defect and shorten the cooling cycle time. This paper introduces a case study that an experiment is conducted to improve shrinkage as the quality characteristic of an injection molding product (automotive seat housing) by optimizing conformal cooling channel design using the Taguchi method.

Index Terms— conformal cooling channel, optimization, Taguchi method.
