Extrusion International 6-2025

39 Extrusion International 6/2025 handful were existing customers stopping by to discuss current proj- ects, but we also met a large num- ber of new potential partners inter- ested in Guill’s precision crosshead and tooling capabilities.” The com- pany has contacts in China, Mexico, India, Greece, Turkey, Thailand, the UK, Australia and Algeria. Addi- tional countries include Sweden, Ja- pan, France, Finland, Chile, Poland, Singapore, the Netherlands, New Zealand, Egypt, Indonesia, Ireland, Brazil, Kenya and Switzerland. Several applications stood out to Leary, notably multilayer medi- cal tubing and advanced materials for sustainable production. He ob- served notable interest in tools that handle recycled or bio-based poly- mers while maintaining tight toler- ances and ow balance. Leary was impressed with the scale and diversity of the K Show. “One highlight was seeing the in- creasing integration of digital pro- cess monitoring and AI-driven con- trol systems.” Regarding Guill Tool Europe, Gerjan ter Wal said that one of the goals expressed by visitors was to optimize their extrusion process and that the European of ce can help ensure smooth communication and planning for new production solutions.

Paths to great - er ef ciency in compounding and recycling were also the focus of Co- perion's appearance at K 2025. Co - perion exhibited a ZSK 58 Mc 18 twin screw extruder. This model, with a 58 mm screw diameter, achieves throughputs of up to 2,500 kg/h with low energy consumption and a high degree of automation. Addi- tionally, Coperion displayed an STS 35 Mc 11 twin screw extruder at the same booth; this model has been specially optimized for masterbatch manufacturing. At the Recycling Pa- vilion in the Open Area, Coperion exhibited the added value of its twin screw extruders for recycling plastics. Coperion’s patent-pending ZSK FilCo ltration compounder was on view there. Both Coperion’s ZSK and STS twin screw extruders excel with their high performance. Both series pos- sess a very high speci c torque – that of the ZSK Mc 18 is 18 Nm/cm 3 ; on the STS Mc 11 it is 11.3 Nm/cm 3 . The torque 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-ef cient - ly when processing products with torque requirement. Moreover, de- pending on the high lling level in the process section, the compound quality is outstanding. Together with both extruder series’ high level of automation, the costs per kilo of compound produced is compara- tively low, and the return on invest- ment is quickly reached.
