Kuhne GmbH

Cascade-Extruder for thermoplastic recycling. For technical end-products such as the furniture or / and automobile industry. Mostly coextruded 3-layer applications.

Extruder for clean-room applications in the medical sector. For medical tubes, coextruded, multi-layer tubes. thermally bonded tubing, spiral re-inforced tubing, micro tubing.

Regardless of all development potential and knowledge of materials, products, and production processes, not even the most sophisticated thought out lines could operate properly without the proper components, such as flat dies with a width of up to six meters, multi-layer feedblocks for up to 11 layers, blown film die heads for up to 13 layers, extrusion screws, barrels, and many more.
We have accumulated our knowledge and technical expertise over the course of decades. To use and realize it even more efficiently, we consolidated it in the form of K-tool GmbH in 2011. Approximately 30 staff are turning the great distinguishing characteristics of KUHNE extrusion lines into reality using a state-of-the-art machinery fleet. Of course, we are lending our professional competence to other companies in the plastic-machine industry as well.
