On Aluminium Extrusion
Flow front tracking in aluminium extrusiondies by means of particle trajectories:
A.J. Koopman, H.J.M. Geijselaers, J. Hu´ etink
As aluminium extrusion process gets more complex the focus is now on dies with tighter requirements.

The Role of Rheology in Polymer Extrusion
John Vlachopoulos
The science of deformation and flow of materials is known as Rheology. The time constants for flow of polymeric materials is of the identical order of magnitude as their processing time for extrusion.
