Abstract: In plastic injection molding process, poor mold cooling conditions will cause the molding defects such as deformation, warpages of the products. An efficient cooling design can significantly reduce the cooling time, and in turn increase the productivity of the injection molding process. On the other hand, severe warpage and thermal residual stress in the product may result from non-uniform cooling. Warpage and sink marks can significantly affect product quality, especially in terms of appearance and precision. In this study, the uniformity of cooling and the deformation effect were observed in the injection mold with the automatically designed cooling channel through a verification experiment. Based on the molding experiment, the cooling and deformation effects were investigated. Results of resin cooling uniformity, temperature distribution of molding parts and deformation of mold were demonstrated.
