Abstract
AbstractAdditive manufacturing abilities of producing highly complex geometries has inspired mould designers to redesign plastic injection moulds. This facility has overcome all conventional manufacturing limitations for designing conformal cooling channels. Such ability ensures a better quality with a homogenized temperature distribution and decreased cooling time. However, in order to improve the cooling system efficiency, its geometry has to be optimized. Thus, multiple algorithms have been developed in order to achieve this goal. However, this depends on the first configuration which is realized according to the designer’s experience. This paper presents an optimization method for geometrical features of the first configuration. A cooling system of a plastic injection mould has been redesigned for additive manufacturing using the optimized dimensions. Thermal analyses of both moulds with conventional and conformal cooling systems have been carried out aiming at comparing the results in terms of cooling time.KeywordsAdditive manufacturingPlastic injection mouldingConformal coolingDesign optimization
