Fabricating conformal cooling channels (CCCs) is now easier and more economical because of recent advances in additive manufacturing. CCCs offer better cooling performance throughout the injection molding process than typical (straight drilled) channels. The main reason for this is that CCCs can follow the courses of molded objects, whereas regular channels cannot. CCCs can be used to speed up cycle times, decrease thermal strains and warpage, and produce a more uniform temperature distribution. Using computer-aided engineering (CAE) simulations, designs that are both effective and economical can be made. The goal of this study is to optimize the design of an injection mold to speed up ejection and improve temperature uniformity. This work developed an optimization approach that improved the position of cooling channels during the mold design stage, enabling the construction of geometrically pre-optimized molds. It is safe to assume that the developed technique is efficient and suitable for the task’s intended objectives.
