During the last decade, finite element simulations have became a very useful technology for tool designing, especially in such cases, like in the extrusion process, where on-plant die trials are expensive and sometimes of difficult interpretation. However, even if good die-design practices are well known by the leading industry players, quantitative evaluations of commonly adopted die-design solutions are seldom available in literature. This contribution presents the preliminary results of a new approach for porthole dies design optimization by means of finite element analysis using HyperXtrude® software.
