This contribution is focussed on numerical simulations of realistic extrusion tools of rubber profiles. The underlying material parameters provided by material characterization procedure which is based on capillary–experiments in combined with die swell measurements. The simulations were performed with the CFD program POLYFLOW under usage of an inverse calculation approach. The validation of these simulations is performed by comparison predicted andf measured dimensions of the already fabricated tools. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
