Abstract: This paper was associated with cooling process of injection molding with an insert of high thermal conductivity. Based on boundary element analysis theory, mathematical models for molds and inserts were first formulated. Through a heat transfer analysis on the contact interface between the inserts and molds, a coupling integration analysis model was obtained. Through a case calculation and a comparison between the cooling processes of injection molds with and without inserts, the feasibility of the algorithm was confirmed, which could reveal how the insert affected the mold temperature.
