Optimize Your Extrusion Process Through Experimental Modeling

THEextrusion is a process complex thermomechanical process, and it is not uncommon for the material to encounter difficulties in reaching the exit of the die or to present defects and variability.

While the extrusion of common polymers is now well mastered, many materials still pose difficulties. Bringing the material to the appropriate temperatures to soften it, drive it and homogenize it in the screw system and then form it is in fact nothing trivial.

The process adjustment parameters being multiple, the operator's know-how is crucial to determine by trial/error the operating optimum. However, the small-scale pilot tests sometimes carried out do not avoid all difficulties during the scale-up.

Numerical simulation requires a lot of data on the rheological and thermal behavior of materials and simplifying assumptions, despite the accuracy of geometric models.

In order to support the reliability of tests and problem solving, RHEONIS has developed an original approach to experimental modelling. Less resource-intensive than pilot testing and digital simulation, this pragmatic approach makes it possible to determine operating windows within short deadlines.
