The planning of the process part of MARIS co-rotating twin-screw extruders concerns a group of functional modules composed of barrels and, at their inside, of transport and kneading elements at variable geometry, which are mounted on shafts for the motion/shear transmission.
The concept of the functional modules originated from the necessity of achieving a perfect correspondence between the extruder hardware component and the process phases that can be identified with a whatever compounding or reactive extrusion.

The equipment capacity to meet with the process requirements can be found, first of all, in the technicians ability to precisely establish the physical or physico-chemical phenomena occuring inside the machine, both in qualitative and in quantitative terms.
