This work presents the design of an injection mold cooling system for the production of a plastic automotive door module. The traditional cooling channel with straight-line drilling could not cool the mold effectively, and the cycle time was longer than expected due to the varying thickness of the parts. Therefore, a specially designed cooling system has been proposed. Instead of a straight line, the cooling channels were in spiral form. This shape could only be fabricated via selective laser melting 3D printing technology with metal powder. In order to save the manufacturing cost and maximize the efficiency of the proposed cooling system, the mold was designed with special inserts and optimum geometrical parameters. The design process was done by using a combination of the analytical and numerical simulation methods. In addition, the real mold was produced and tested in order to prove the efficiency of the new cooling system. The research result showed that the cooling time was reduced by approximately 23 %, as compared to the traditional cooling system. This is a significant practical contribution to the injection molding technology.
