Application of QForm Program for Improvement of the Die Design and Profile Extrusion Technology

Nikolay Biba, Sergey Stebunov, and Alexey Vlasov, QuantorForm Ltd., Moscow, Russia

Track: EXTRUSION/DIE, THEORETICAL - Modeling and Simulation

ABSTRACT --- The program QForm for finite element simulation of the profile
extrusion process has two modes. One mode is for transient simulation of the first
stage of the process when the material is filling the dies, and another mode is for
stationary stage of the process when the profile has left the die orifice. The
developed code provides completely automated mesh generation, effective
simulation of the material flow, and output of the information on material flow,
temperature distribution, and some integral characteristics like profile bending
and profile twisting, which are necessary for prediction of product quality. The
developed software was applied to simulation and optimization of different
extrusion processes, including profiles having opened and closed shapes. The
code is an effective tool for extrusion technology development in industry, due to
its user-friendliness and use of the PC.
