Sensitivity Analysis of Conformal Cooling Channels for Injection Molds: Two-Dimensional Transient Heat Transfer Analysis

In recent years, conformal cooling channels (CCCs) have become simpler and less costly to produce. This was largely the product of recent developments in additive manufacturing. In injection molding engineering applications, CCCs provide superior cooling performance compared to the usual usage of straight-drilled channels. This is because CCCs can be conformed for more uniform cooling of the molded part. Using CCCs decreases cooling time, total injection time, thermal stresses, and warpage by a significant amount. Despite this, CCC design is more difficult than conventional channel design. The production of a cost-effective and efficient design is dependent upon CAE simulations. This inquiry focuses on the sensitivity analysis of design features in preparation for the adoption of a design optimization approach in the future. The goal is to optimize the position of cooling channels (CCs) so as to decrease ejection time and promote temperature distribution uniformity. The ANSYS Parametric Design Language (APDL) parametrization and the given design variables are useable and may be used in future optimization attempts.
