摘要
This paper presents an application of additive manufacturing (AM) technology that is suitable for manufacturing injection molding tools with conformal cooling channels to increase productivity. The design and the manufacturing of a hybrid injection molding insert by combining machining and selective laser melting (SLM) technologies was analyzed. A simplified finite element cooling analysis was used to compare conventional and hybrid solutions for the design of cooling channels to decrease the injection cycle time of an automotive plastic part. The simulation results showed that, by using a hybrid steel/high-conductivity copper alloy with conventional cooling for the design of the mold insert, the injection cycle time can be reduced by 50.3%, and by using hybrid steel/steel with conformal cooling, the injection cycle time can be reduced by 65.6%. The hybrid injection molding insert with conformal cooling made by selective laser melting (SLM) technology was successfully tested under real production conditions confirming the significant reduction of the injection cycle time.
