Extrusion International 6-2025

30 Extrusion International 6/2025 К 2025 duction reliability thanks to its automatic self-cleaning and high process stability. Several open house events were held at the compa- ny’s headquarters in Bad Oeynhausen in parallel with the trade fair, which drew signi cant interest. Vari - ous recycling processes were demonstrated, including odour reduction for polyole ns and processing PET materials using OMNI recycling systems. Many inter- national visitors took the opportunity to see the tech- nologies in action. With positive feedback, successful sales and strong visitor interest, Gneuss can draw a very positive conclu- sion from its participation in K 2025. Gneuß Kunststofftechnik GmbH www.gneuss.de Open House event at Gneuss in Bad Oeynhausen High-Performance Extruder Series Extended The solEX NG 105 model, which completes the se- ries of the most powerful single-screw extruders from battenfeld-cincinnati and provides a further optimally matched size level, celebrated its premiere at this year's K show. The series comprised the 45, 60, 75, 90 and 120 models. The solEX 105 lls the performance gap between the two large extruders perfectly. Naturally, the 105 machine with a length of 40 D, which covers a performance range from 1,680 to 2,100 kg/h, offers all the familiar features of the previous models and also in- cludes valuable new innovations. The machine is also equipped with a newly developed water supply. The solEX NG 105 has its own internal water supply, which is lled once with water includ - ing corrosion protection. Previously, the extruder was usually supplied with water for cooling the processing unit, gearbox and motor via the service water pipe in the processing plant. This can have two main disadvan- tages: Firstly, the impurities contained in the water, e.g. sand, can cause cooling channels to become clogged. Secondly, the cooling water reaches the components at a constant, usually low temperature. While cold water is advantageous for cooling the processing unit, it increas- es the lifespan of the engine and gearbox if the cooling water is at a low temperature. These requirements are met by the own water supply, which is mounted on the extruder. “The extruder's own water circuit is so con - vincing that we will be providing it for all our models in future,” promises Heinrich Dohmann, Director Me- chanical Engineering. All solEX extruders of the NewGeneration (NG) have a processing unit consisting of an internally grooved bar- rel in combination with a matching screw and grooved bush geometry, resulting in technical process advan- tages: a reduced axial pressure pro le reduces machine wear. In addition, high speci c output rates at low screw speeds ensure high ef ciency and gentle, but very ef - fective and homogeneous melting performance reduce the melt temperatures by around 10°C. This enhances the quality of the end product and results in energy sav- ings. Compared to the predecessor model in the solEX series, the NG models achieve around 25% higher out- put when processing HDPE and even up to 40% higher output with PP.
