Extrusion International 6-2025

60 Extrusion International 6/2025 RECYCLING Howdo you see the future of ltration in the context of the circular economy and sustainability? Schmitz: Filtration already plays a key role in recycling and will become even more critical if we want to achieve really high recycled content in high quality products. To do this, lters have to perform well under high levels of contamination while remaining ef cient. What’s more, sustainability doesn’t just start with the product, but with the process design. I believe that solutions such as COBRA help to ensure that recycling remains economical, becomes more ef cient and becomes even more wide - spread in industrial applications. BB Engineering GmbH www.bbeng.de Intelligent Automation The more precisely the machine parameters can be matched to the input material, the higher the through- put and better the quality. PURE LOOP developed Dy- naShape® as an intelligent automation solution for the ISEC evo recycling machine to optimise settings on its own and maintain a consistent recycling process even when the feed material changes. PURE LOOP, amember of the EREMAGroup, launched the next stage in development of the proven ISEC evo machine for recycling production waste at K 2025 in Düsseldorf. The new DynaShape® technology responds to changes in feed material shape and bulk density by automatically adjusting the machine to get the best possible results from the polymer. During exhaustive test runs that simulated different stages of production, including changes in the input material, PURE LOOP clocked an increase in productivity of up to ten percent. A stable recycling process that is easy to operate The ISEC evo has made its mark as a true material all- rounder over the past ten years. The integrated shredder- extruder combination with patented double feed ram system and conical transition to the extruder reliably pro- cesses clumps, guillotined rolls of lm, lm shreds, glass bre-reinforced plastics and bres into high-quality recy - cled pellets. Previously, an experienced technician was of- ten needed to optimise the relevant machine parameters. Now, DynaShape® carries out this task automatically, en- suring that themachine operates consistently atmaximum potential in all applications. This signi cantly reduces the time and labour required to get the best output. "DynaShape® regulates our recycling machine to get the perfect settings. It does it as precisely as a profes- sional technician with ten years of experience," says Manfred Dobersberger, Managing Director of PURE LOOP. "Our customers get the advantage of higher throughputs with consistent high quality and a notice- able reduction in operator workload. The technology is in a class of its own when processing challenging ap- plications with uctuations in feed material shapes and bulk densities; tasks for which the ISEC evo is pre- destined." These kinds of applications involve injection mouldings with material shapes ranging from start-up lumps to sprues and regrind, and PVC pipes, where production waste ranges from large sections of pipe to shavings (the ne chips produced during machining). The dynamic technology duo The core of DynaShape® is based on the interaction of two components. The proven double feed ram system, which now dynamically adjusts its speed to the rotor load, while the hydraulically adjustable intake apertures adjust automatically - instead of manually as before. Throughput is increased as a result, and so is the quality of the melt. Thanks to the consistent melt pressure and optimumextruder screw lling level, there is no oxidative degradation of the melt. What is more, the temperature of the melt can be trimmed automatically on a case-by- case basis by setting a maximum temperature for each polymer. In contrast to manual operation, DynaShape® reacts immediately to increases in temperature to make sure that the speci ed limit value is not exceeded. Another practical feature is that the intelligent Dy- naShape® settings can be saved as a recipe. This means that the next time it is started up, the machine operates immediately with the optimum setting, further reducing the time required for manual intervention.
