2、ph Becker,Pavel Hora Abstract The use of finite element analysis (FEA) to predict material flow and die deflection is well implemented in the scientific community but it is still new in the extrusion industry or for die makers. This paper deals with the advantages and limitations of FE-analysis to p

3、redict material flow and to optimize die design from an industrial point of view. For this study two software packages, HyperXtrude and PF-Extrude, have been used to predict the material flow in two applications, the optimization of a heat sink profile and the filling process of a porthole die.

Introduction The use of FEM simulation software for the design of extrusion dies is a promising possibility for both, extruders and tool makers. The available software packages offer user friendly i

The modelling of friction conditions during extrusio

6、n, especially in the bearing channel, has been the focus of research throughout the last years 5, 6. Even though some of the results and findings are of secondary importance to extrusion tooling designers, the influences of the extrusion speed and the possible tool deflection due to inhomogeneous material flow offer great advantages to them. The possibility of die design corrections without the need of field testing not only saves time and money but also leads to a satisfied customer. O
