Highest Torques with Maximum Efficiency

The twin-screw extruder gearboxes by RSGetriebe are the ideal solutions for the plastics and foodstuffs industries. Highest torques with maximum efficiency and reliability are their attributes.

Every twin-screw extruder gearbox is designed to meet the customer’s exact requirements. As a central component of the extruder, the speed of rotation of the screws and the output torque are realized according to your specifications. The twin-screw extruder gearboxes are standardly available with centre distances of between 18.5 mm and 76 mm from RSGetriebe. Other sizes can be custom developed to the customer’s specifications.

In addition to the extrusion and compounding process, extruder gearboxes are also used as side dispensers for mixing in additives. A bevel gear stage can also be implemented here.
