Co-rotating twin-screw extruder TSK-HV


Highest free volume

TSK-HV, the high-volume extruder from Theysohn - with a diameter ratio of Do/Di 1.83 it is ideal for products with a light bulk weight and low energy requirement, as well as for shear-sensitive materials. The large free volume guarantees an extra advantage in output for bulky products and provides the user with added value due to an extended production window.

The TSK-HV provides the user with the largest-possible added value for that extra output with an extended production window. The Theysohn TSK-HV Compounder is based on the successful TSK Compounder and impresses with its excellent process design allowing it to be used for all compounding tasks.
