Performance. Perfected. For you - under this motto, KraussMaffei will be demonstrating at K 2025 how cutting-edge technologies and a strong customer focus deliver measurable added value. The spotlight in extrusion technology is on solutions for more efficient and future-proof plastics processing - from large-scale industrial polymer manufacturing to pipe and profile extrusion and to cost-effective recycling processes. The trade fair presentation will be complemented by digital innovations paving the way towards smart, low-operator production.
“Performance. Perfected. For you. reflects our commitment to delivering advanced extrusion solutions - technically refined, highly efficient, and consistently geared to the requirements of our customers”, says Ralf Benack, Managing Director of KraussMaffei Extrusion GmbH. “Our strength lies in the combination of highly developed mechanical engineering and deep process know-how – all from a single source, reliably delivered worldwide.”
The development roadmap for the coming years is clearly defined: "We are working specifically on new developments to continuously increase customer benefits, actively maintaining our products and resolutely driving forward the digitalization and automation of our products." This is how KraussMaffei Extrusion is creating the foundation for sustainability, economic success and technological progress. "And we are making this tangible for visitors at K 2025 in Düsseldorf," says Ralf Benack.
Future market petrochemicals: New processing extruder for raw polymer production
One of the recent key developments is the new generation of ZE Petrochemical (ZE-PC) compounding extruders, purpose-built for the demanding needs of large-scale polymer production. Based on the proven BluePower technology, the co-rotating twin-screw extruders - available with screw diameters up to 400 mm - combine energy efficiency with high processing quality.
“Thanks to a D/d ratio of 1.65, torque densities of up to 16 Nm/cm³, and variable-speed drives, the machines can run at lower screw speeds without compromising throughput. This lowers the specific drive power and reduces the melt temperatures, which lowers the risk of degradation,” explains Dr. Thomas Unger, Vice President Technologies at KraussMaffei Extrusion. At the same time, the larger diameter ratio ensures significantly more effective degassing. "This allows us to offer our customers an economical, reliable and material-friendly solution," he adds.
More output, less investment - optimized recycling processes
From bottle-to-bottle PET recycling to material preparation for chemical processes - as a driver of innovation in the circular economy, KraussMaffei Extrusion offers pioneering solutions for all forms of recycling.In the PET recycling sector, KraussMaffei Extrusion is presenting a high-performance twin-screw system based on the BluePower series for throughputs of up to 12 tons per hour. The concept responds to the increasing demand for higher output and more energy- and cost-efficient processing. Compared to conventional twin-screw systems, energy consumption can be reduced by up to 20%. The systems are compatible with standard SSP units and produce food-grade rPET.
In chemical recycling, KraussMaffei Extrusion is focusing on key technologies: high-performance extruders for processing material streams - for example, to produce pyrolysis oils - efficiently implement crucial process steps such as dewatering, degassing and the removal of impurities. Pressures of up to 200 bar and the retractable UltraGlide system with easy-to-maintain screws enable customized solutions for demanding recycling applications.
KraussMaffei Extrusion has also refined its EdelweissTechnology for processing recyclates more efficiently - even with fluctuating material properties. The focus is clearly on process optimization and cost efficiency. The twin-screw extruder covers all process steps: degassing, filtering and compounding. “This integrated setup can lower investment costs by up to 25%,” says Dr. Thomas Unger.
