Quality produced in Germany
An international team of experts
The Theysohn Group is a pioneer in the extrusion industry: With the new extrusion series, it is the only one in the world to supply extrusion lines that have been developed and built in-house and that have been optimized in terms of process technology.
Co-rotating
twin-screw extruders
With the co-rotating twin-screw extruder TSK Theysohn presents a series with outstanding flexibilty which meets your requirements on process. Theysohn TSK twin-screw extruder impress with their modular constructed process parts for barrel and screw and for their efficient temperature control at highest screw speed and torque.
Further we have with the TSK-HV a high-volume series in our portfolio, which is suitable for shear-sensitive products and materials with high volume requirements and the TSK-PCE which is able to process a wide range of formulations; the opening process section is ideal for battery compounds, powder coating formulations or adhesives.
Extruder Components
For many decades the name THEYSOHN has stood for high-performance products for plastics and rubber processing. THEYSOHN products are shipped from the Salzgitter factory to many countries around the world. As essential components, they are used in machines of many renowned manufacturers and processors.
Developments were geared towards wear-protected plasticising units at an early stage. Optimum solutions are offered with wear-protected designs of barrels, housings and screws. The production of well over forty thousand screws and barrels in a wide variety of sizes and designs has allowed extensive development and production know-how to mature.
Perfect individual parts alone do not make sense.
Our roots go back several decades to one of the first producers of parallel and conical extenders and extrusion tools in Europe. Today these companies work together under the registered umbrella brand Theysohn. We operate two strong European production sites with experienced staff in order to guarantee effective know-how and high capacities.

Chronicle Part 4 – A New Era of Independence, Innovation & Global Presence
Chronicle Part 4 – A New Era of Independence, Innovation & Global Presence
From 2000 to 2025, Theysohn entered a new chapter shaped by strategic ownership changes, international growth, and technological realignment.
In 2003, Rudolf Zahradnik, Siegfried Topf, and Sven Wolf acquired the Austrian companies of the Theysohn Group via an asset deal, marking the beginning of a new independent era. Global expansion followed quickly: in 2004, Theysohn India and Theysohn Russia were founded, and by 2007, a joint venture in China had been launched.
Over the next decade, ownership evolved—from the takeover by High Tech Industries AG in 2008 to the management buyout in 2014 by MUT Holding (Michael Döring, Uwe Langanke, and Torsten Grosser), who led the company into a more focused and agile future.
Production and engineering were restructured: in 2016, assembly was consolidated in Germany, while technology, development, and sales of counter-rotating extruders moved to Stockerau, Austria. In 2017, a new facility was built in Pune, India, boosting local service and manufacturing capabilities.
In 2019, the company underwent a strategic realignment, unifying operations under Theysohn Extrusionstechnik GmbH Germany. And as we look to 2025, we celebrate not only our technological advances—such as TSK-Kaskade and counter-rotating extruders for North America—but also the people behind the brand.
This anniversary is a moment to say thank you — to our employees, partners, and customers. Together, we’ve made Theysohn a forward-thinking company built on tradition, innovation, and heart.
