Twin screw extruder provides flexibility, throughput, competitiveness.

The TM--HS twin screw extruder is said to provide more flexibility, more throughput and more competitiveness, according to the company's six-page, four-color brochure. The TM--HS Series extruder is characterized by a D/d ratio of 1.65 with a maximum screw speed of 1,300 rpm. The torque has been increased by more than 20% with respect to earlier HT Series models.

This solution is said to allow the company to use a bigger free volume, and an enhanced available torque, permitting increased production either in the case of a high power request or when it is necessary to feed an elevated percentage of fillers and/or additives.

Thanks to the highest performing materials used to manufacturing some of the elements composing the extruder, these machines can be applied in the more advanced compounding and reactive extrusion processes, according to the literature.

The planning of the process part of the company's co-rotating twin screw extruders concerns a group of functional modules composed of barrels and, on the inside, of transport and kneading elements of variable geometry which are mounted on shafts for the motion/shear transmission.

The concept of the functional modules originated from the necessity to achieve a perfect correspondence between the extruder hardware component and the process phases that can be identified with either compounding or reactive extrusion. The equipment's capacity to meet process requirements can be found in the technician's ability to precisely establish the physical and physico-chemical phenomena occurring inside the machine, both in qualitative and quantitative terms, according to the company.
