Extruder gearboxes

From the very beginning, Kissling played a key role in the development of ZSK twin helix extruder drives for plastic and foodstuff extrusion, including the EX gear unit series, which was developed in-house precisely for this purpose.

Kissling worked together with leading system builders to develop compact gear units capable of transferring high torques via shafts that have relatively small cross sections. They can also withstand incredibly high axial forces thanks to an optimum arrangement of the tandem bearings. Kissling's portfolio also contains in-house solutions for single-shaft extruders and kneading machines.

Kissling developed the VZD gear unit series especially for kneading machines. This gear unit enables the worm shaft to move axially at high speeds and power levels.
