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

Kissling has 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.

Dual-shaft extrusion with shaft guide
This gear unit was developed as a specialty product, which allows coolant to be fed through the worm shaft.

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