Track: EXTRUSION/DIE, THEORETICAL - Modeling and Simulation

ABSTRACT --- Even though extrusion is often regarded as a semi-stationary process, the
deformations of the die at the beginning of the process can have great influence on the
process later on. During filling of the die, the deformation of the die depends on the location
of the flow front, up to a point where parts of the profile will be opened or closed, especially
in porthole dies. In this paper we present an accurate 2-D method to simulate the filling of
extrusion dies. The method is based on the pseudo-concentration technique. We compare
different options to model the pseudo material, and choose the best option.
