Kuhne Extruder

KUHNE Extruder

In the focus of development are the single screw extruders, which are built in screw diameters from 25mm to 250mm. Possible lenghts, related to the diameter, are 20 D, 24 D, 30 D, 33 D, over 36 and 39 D up to the special lenght of 45 D.  They can all be produced in our factory

All extruder sizes are available without venting, single, double or four-fold vented. Modern screw geometries guarantee constant pressure and proper homogenization with maximum output rates. In addition to processing plastics, KUHNE extruders are also used to process biodegradable materials, wood flour or fibre reinforced plastics as well as other extuderable materials.

KUHNE manufactures more than 200 extruders annually in the Sankt Augustin headquater. In addition to custom made extruders, we manufacture certain machine types in series to assure short delivery and short payback time.
