Coperion shows off new twin screw extruders


Two new twin screw extruders occupied centre stage at Coperion’s main compounding stand at K2025. The new ZSK 58 Mc18 twin screw model has a 58 mm screw diameter, achieves throughputs of up to 2,500 kg/h with low energy consumption and a high degree of automation. It has a high specific torque – 18 Nm/ cm³ – which is directly transferred via the gearbox and the screw shafts onto the rotating twin screws in the process section, making it possible to achieve very high throughputs economically and energy-efficiently when process- ing products with torque requirement. At the show, Coperion exhibited


the ZSK 58 Mc18 with new screw elements that it has developed especially for processing fillers. These reduce wear in the melt zone while simultaneously increasing throughput. Kathrin Fleuchaus in the communica- tions department said that new features that enhance efficiency include condition monitoring for the gearbox. This feature can also be accessed in C-Beyond, the company’s digital platform for operational data. A new feature of C-Beyond is the Lifecycle Manager, which is for predictive maintenance planning,


The twin screws of the new ZSK 58 Mc18 extruder were open to view at K2025


Fleuchaus said. The tool computes upcoming maintenance and repair tasks for all components of a Coperi- on extruder, based upon operating hours and performance, and reports them in advance. The Lifecycle Manager has already been used successfully on several pilot machines and Coperion says customers have been able to improve their machines’ OEE significantly.


A new sustainability app in C- Beyond calculates a CO2-equivalent reading during compound produc- tion, based on measurements in the extruder’s main drive and all other electricity-consuming components. A new STS 35 Mc11 was the other


twin screw extruder on the Coperion stand. Designed for masterbatch production, it achieves throughputs of up to 300 kg/h. The closely intermesh- ing twin screws allow for an absolutely even distribution of the ingredients while ensuring effective self-cleaning in the process section, says the company. The STS extruder was shown equipped with a Coperion AccuRate Series 602 volumetric feeder, a new unit that Coperion was able to demonstrate following its acquisition of Schenck Process FPM and its feeder product lines.


At another stand and an outdoor


area, the Coperion group showed more new technology; for example, the Coperion K-Tron K2-ML-D5-T35 feeder equipped with Electronic Pressure Compensation, a ZSK recycling extruder, and the Herbold Meckesheim SMS 80-200 Granulator. � www.coperion.com


Adeka claims unusual award recognition


Japanese chemical com- pany Adeka revealed at K2025 that it had achieved the feat of being awarded a Guiness World Record, the honour being granted to its new product Transparex in the category ‘Most effective clarifying agent for polypro- pylene transparency 2025’. The product’s name is a


combination of ‘transpar- ency’ and ‘transformation,’

with X symbolising unknown possibilities. Adeka claims Transparex promotes superior transparency and typically has better haze value than comparable products, along with enhanced mechanical properties. This makes it comparable to polystyrene and PET, and reduces additive usage which in turn lowers production costs.


COMPOUNDING WORLD | November 2025 The additive’s versatility


means it can be used in applications ranging from household goods and cosmetics to medical devices and automotive parts. It has also been FDA-approved for food contact applications. At a K2025 press confer- ence marking the European launch of Transparex, Hidetaka Shirozume,


President and CEO of Adeka, remarked how the global plastics industry is currently in a ‘transforma- tive’ stage. “Companies are generally being more pragmatic,” he said. “But this state of flux has spurred innovation, forcing them to rise to challenges and look outside the box to find solutions.” � www.adeka.co.jp
