Abstract Because of recent advancements in additive manufacturing, fabricating conformal cooling channels (CCCs) has become easier and more economical. In the injection molding process, CCCs provide higher cooling performance than standard (straight drilled) channels. The major reason for this is that CCCs may follow the courses of the molded geometry, whereas typical channels created using traditional machining processes cannot. Using CCCs can reduce thermal strains and warpage while also improving cycle time and achieving a more uniform temperature distribution. CCC, on the other hand, has a more complicated design procedure than traditional channels. Simulations using computer-aided engineering (CAE) are critical for achieving an effective and cost-effective design. This article compares two ANSYS modules for the purpose of validating results. It can be inferred that the two modules produce similar results for models with fine mesh. As a result, the ANSYS module to work on should be chosen depending on the job's goal as well as the CAD geometry's complexity.

The challenging in injection molding process is to get the uniform thermal distribution on the molded parts during the cooling stage which is mainly depend on the design of the cooling channels in injection mold. Poor design of cooling channels will result a non-uniform thermal distribution which lead to a longer cycle time, differential shrinkage and warpage defects on the molded parts. In this study, the performance of conformal cooling channels compared to the straight drilled cooling channels in order to minimize the warpage on the front panel housing is evaluated. The simulation results from Autodesk Moldflow Insight (AMI) 2013 are analyzed by using Taguchi Method and Analysis of Variance (ANOVA). The analyses show that conformal cooling channels are able to improve the quality of the molded parts in term of warpage compared to the conventional straight drilled cooling channels and the results are beneficial for the molding industries which involving the precise parts.
