Optimal process

In aluminium extrusion it is important to master the thermal evolution of the press elements, the billet and the forming profile. Chosing the right set of process and operational parameters is necessary if you want to extrude high quality profiles and reach higher extrusion speeds for big runners. This is why MTD performs virtual trials by full 3D transient simulation of the press cycles. Reliable and quick 3D predictive models take into account material flow, heat sources and losses in an accurate manner. In the conception phase as well as during the process itself, numerical modelling allows to increase lifetime of the parts, process productivity and final product quality, increase the lifetime of critical parts and save on trials costs.
