Extrusion

QForm-Extrusion is a single program that integrates all the features required for analysis and optimization of the most complicated extrusion processes. It is used for simulation of solid, semi-hollow and hollow profiles as well as extrusion through multi-hole dies. The extruded material can be aluminum alloys, brass, steel and other metals.


Solid extrusions and hollow extrusions

Multi-hole dies and brass profile extrusions

QForm Extrusion has a built in bearing editor that allows for rapid modification of bearing lengths and angles. You can quickly experiment with bearing design to see how it affects the material speed and the shape of the extrusion.

The program is fast and reliable. It works on a 64-bit Windows platform and takes advantage of parallel computing on PCs with up to 8 CPUs. A series of simulations can be run overnight or over weekends using the built-in batch mode.

Benchmark tests — QForm has done very well in recent benchmarking tests of the various extrusion simulation software available on the market. In the most recent benchmark tests held in Germany in late 2009 the test extrusion was done for four angular profiles going through a multi-hole die. The use of differently shaped chambers caused variation of the extrusion velocities for each profile. QForm-Extrusion was able to outperform the other software and it has shown very good correspondence of the simulated profile velocities with the experimental results.

Setting up and running an extrusion simulation is easy with QForm.
The program provides everything you need to run a simulation and analyze the results.


You design your die in cad as usual



You import the die profile into QForm where QForm can create the chamber



QForm applies FEM to the die



The wizard walks you though setting up the simulation



You run the simulation and see the results




If results are not what you expected you can use QForm's bearing editor to modify your bearing design.


It is so easy to modify the bearing design with QForm's bearing editor. You can just click and drag to change lengths and angles or you can edit the values numerically.
