Header Extruder

Extruder from KUHNE

The art of extrusion.

The focus of development is on single-screw extruders, which are built in sizes with screw diameters ranging from 25 mm to 250 mm and lengths, in each case based on the diameter, of 20 D, 24 D, 30 D, 33 D, through 36 and 39D to the special size of 45 D.

All extruder sizes are available with or without venting, venting possible in double or even quadruple execution.

Modern screw geometries ensure pressure constancy, good homogenization and highest output values. In addition to plastics, KUHNE extruders are also used for processing biodegradable materials, wood flour-filled or glass fiber-reinforced plastics, and other extrudable materials.

On average, more than 200 extruders leave our plant in Sankt Augustin every year. In addition to customized extruders, KUHNE builds certain machine types in series to ensure short delivery times at a favorable price/performance ratio.
