Extrusion Asia Edition 1-2024

T ogether, Coperion and Herbold Meckesheim offer operators broad expertise in technology and process solutions for plastics recycling. Since their merger, both companies have con- tinued to develop and optimally attune their technologies so that entire systems excel in operation with extremely high effi- ciency. At Chinaplas, Coperion and Herbold Meckesheim will display a virtual PET recycling installation. Visitors to the booth can peer inside key components of the recycling installation and see for themselves the process-technical details in each process step and the high efficiency of each component. Other exhibits at Booth F106 in Hall 2.1 include the Coperion ZSK 26 Mc 18 twin screw extruder with a K-ML-SFS-KT20 twin screw feeder from Coperion K-Tron, a Coperion K-Tron T35-QC quick change feeder shown with a 2415 vacuum receiver for refilling ingredients, and a C/S-LW-NT28 twin screw feeder from Colormax system will be shown with STS 75 McPLUS ex- truder. In addition, Coperion K-Tron will be introducing the Pro- Rate PLUS line of gravimetric single and twin screw feeders to the Chinese market, showing a PLUS-S feeder with refill. A CVH 550 high pressure rotary valve for granulates will also be on dis- play. STS 75 Mc PLUS: Higher Throughput with Improved Compound Quality For the STS 75, Coperion has raised the specific torque of the STS twin screw extruder from 11.3 Nm/cm³ to 13.6 Nm/cm³. The compounder thus achieves improved product quality and at the same time up to 20% higher throughput in every appli- cation. Critical to this level of performance, along with process- technical modifications, is optimization of the drive’s key com- ponents. The new STS 75 Mc PLUS extruder is equipped with a high-power motor and a gearbox designed specifically for the high torque. Proven high-performance materials for the screw shafts ensure full torque transmission from the gearbox to the screw elements. The higher fill level in the process section is crucial to the im- proved compound quality that the STS 75 Mc PLUS achieves. It reduces both shear stress and melt temperature and improves mixing behavior. The result is an extremely gentle product handling at high throughputs. The process section of the STS 75 Mc PLUS is equipped with heating cartridges that generate heat very energy-efficiently exactly where it is needed. STS extruders combine the advantages of substantially stan- dardized and thus more cost-effective machine construction in- corporating Coperion’s technical expertise. In the continued de- velopment of the STS 75 Mc PLUS, Coperion has profited from the comprehensive experience gleaned from its high-end ZSK Mc 18 extruders. The new STS 75 Mc PLUS’s throughput increase of up to 20% makes it a particularly economical solution. Ma- terial costs per kilo drop and return on investment is reached much more quickly. Coperion retained the proven Do:Di = 1.55 ratio of outer to inner screw diameter unchanged, thus ensu- ring secure scale-up to other STS model sizes. Complete Plastics Recycling Plants from a Single Source Coperion and Herbold Meckesheim realize plants for a wide va- riety of plastics recycling applications, excelling in their reliabili- ty and the high product quality they achieve. From mechanical processing – shredding, washing, separating, drying and agglo- merating of plastics – to bulk material handling as well as feed- ing and extrusion all the way to compounding and pelletizing, such plants cover the entire plastics recycling process chain. Together, Coperion and Herbold Meckesheim offer solutions for mechanical recycling of post-industrial and post-consumer waste, chemical recycling, solvent-based recycling, and deodo- rization, tailored to the type of plastic being recycled. 科倍隆楷创在其K2-ML-D5-T35失重式喂料机上引入了可靠的、 高精度的喂料解决方案。 (图片：科倍隆楷创，瑞士) Coperion K-Tron introduces a reliable, high-accuracy feeding solution in its K2-ML-D5-T35 gravimetric feeder (Photo: Coperion K-Tron, Switzerland) 56 2024中国国际橡塑展 – Chinaplas 2024 Extrusion Asia Edition 1/2024
