QForm UK Extrusion

QForm UK 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 UK 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 UK 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.

I have been using QForm UK for a little over 6 months, and I have been very happy with the results that I have gotten. I found the software very easy to use. The average pre-processing time is around 15 minutes... The tech support has been very helpful and very quick with getting me help and any information that I have needed. The results from simulation have been very accurate... Our company as whole has been happy with the purchase of QForm UK.

The tools for complex extrusion profiles can take a long time to design properly. The use of simulation software significantly speeds up the development time of extrusion tooling, eliminates trials in real press, significantly shorten the time to market, predicts the quality of the extruded product and by these means drastically reduce production cost.

ASAŞ Extrusion implements an innovative approach to extrusion technology development that improves final production quality and decreases manufacturing costs. Prior to manufacturing the die and extrusion trials we analyze each profile extrusion process using QForm UK software to predict and eliminate defects and problem areas that can occur during real extrusion.
