QForm Extrusion is the only program in the market that can perform simulations of material flow that are thermally and mechanically coupled to the die deformation even for very complicated thin walled profiles. QForm Extrusion was developed for simulation analysis of material flow during the extrusion process and for analysis of the stress-strain-state of die set. The program features parametric representation of the bearing geometry and state-of-the-art automatic meshing algorithms. By keeping the bearing geometry as a parametric surface, QForm Extrusion is able to consider cases when die deformation causes local zones of very fine inclination of choke or relief that may vary by just a few angular minutes.
Simulation results and actual production of our customers as well as laboratory tests have shown that, though small, such bearing angle variation may significantly influence the material flow patterns. The software has been developed to be used by production engineers and die designers so it is not necessary to know anything about finite element method to run accurate simulations.
