HT-Class

The HT extruders have speeds from 150 to 750 rpm and area available in sizes ranging from 30 to 140 mm. Equipped with modified gearboxes and screw shafts, they can transmit up to 40% more torque than conventional extruders of the same size and screw speed. The HT line is designed especially for those processes requiring high specific energy.

FeaturesPerformance
