Extrusion International 6-2025

57 Extrusion International 6/2025 cepts to optimally adapt the machine to their processes. A hydraulic drive is particularly suitable for applications with frequently changing loads. The robust drive en- sures high torques with a low kW output. The classic electromechanical direct drive ensures high energy ef- ciency and easy maintenance. The measuring machine is equipped with a high- torque drive including servo controller – a new develop- ment from Baumüller in collaboration with Nidec Desch. This direct drive solution is specially designed for par- ticularly demanding applications with dif cult-to-shred plastic fractions. The drive system with high-torque mo- tor achieves a high torque even at low speeds. Thanks to a well-coordinated connection between the drive and the rotor shaft, the power transmission is optimally utilized and a higher drive power is achieved. The inno- vative drive system not only enables cost-saving opera- tion, but also sustainable production. WEIMA C.200 Duo hydraulic press Another highlight at the WEIMA booth was the C.200 Duo dewatering press. Particularly for recyclers of post- consumer plastics, the economical separation of water and plastic residues ( nes) is becoming increasingly im - portant due to high disposal costs. The C.200 Duo dewa- tering press uses a hydraulic pusher cylinder to compact moist plastic akes into almost dry pellets with a diam - eter of 200 mm. The low-maintenance compact machine can be used independently or in production lines. WE.connect – The digital platform for WEIMA machines With WE.connect, WEIMA offers a central platform that bundles all digital service offerings. WE.monitor vi- sualizes machine data, additional information and main- tenance recommendations. Machine statuses, operating data and maintenance intervals can be tracked live using smart sensor technology and cloud-based monitoring. WEIMA is constantly developing the tool and, thanks to early noti cation, enables downtimes to be avoided, ser - vice calls to be planned and productivity to be sustainably increased. The WE.shop enables customers to quickly purchase original parts around the clock. Thanks to the intelligent search function with the machine ID, precisely matching parts can be identi ed and ordered easily. In- depth expertise is provided by the WE.know knowledge database. From step-by-step instructions and mainte- nance videos to technical documentation.

Post-consumer lm recycling becomes increasingly vi - tal, especially in the packaging industry. The challenge of processing lightweight, uffy lms with air pockets, inks, and adhesive layers persists. These materials are notoriously dif cult to handle and often lead to incon - sistent quality and energy inef ciencies. While the conventional cutter compactor route was considered, MAS and Siempelkamp Size Reduction chose to aimhigher – pursuing unmatched performance and quality. Cutter compactors can no longer meet the growing demand for top quality, as their process control cannot ensure a uniform melting process, leading to quality uctuations in the extruder feed. “The iQonicTwin PreDensi er represents the fusion of two proven top technologies and marks a signi cant leap forward in recycling process stability, ef ciency, and product quality.” The machine combines Siempelkamp’s high-per- formance PreDensifier with MAS’s energy-efficient conical co-rotating twin-screw extruder – delivering
