45 Extrusion International 5/2024 ISEC evo also Keeps Composite Materials in the Loop W ith the ISEC evo plastic pelletis- ing system, PURE LOOP offers a high-performance recycling ma - chine for processing a wide range of production waste. In tests with ther- moplastic composites and glass fibre waste, PURE LOOP has already been able to confirmthe highquality of the recycled pellets for return to injection moulding production several times. Thanks to the ISEC evo, produc- tion scrap from various plastics, such as polystyrene, polycarbonate, polypropylene and polyamide, can be gently processed into high-qual - ity recycled pellets. "Our integrated shredder extruder combination is the perfect solution for injection moulders who want to return their production waste to the production cycle in high quality. This is a crucial aspect for a sustainable, cost-effi - cient and resource-saving produc - tion," says Manfred Dobersberger, Managing Director of PURE LOOP. Disposing of scrap parts and sprues from the injection mould- ing process is associated with work and sometimes high costs. Feeding them back to the production pro- cess therefore offers economic ben- efits for injection moulders. "Our ISEC evo sets new standards in the recycling of injection moulded parts by ensuring a consistently high quality of recycled pellets," explains Dobersberger. In contrast to grind - ing processes, only minimal changes in the Melt Flow Index (MFI) occur during repelletising and there is no dust, which promotes the formation of soot particles. The regranulate has the same shape and melt per- formance as virgin material, which makes it easier to feed back into the injection moulding machine. The system, which is equipped with a melt filter, also copes excel - lently with challenging materials of different sizes and shapes. The use of high-quality carbide knives, a protected rotor, special treatment of the screw flights and other mea - sures increase the wear resistance of the system. As a result, composite materials or glass fibres can also be optimally processed. "During tests in August at our R&D Center in Ans - felden, the ISEC evo was once again able to prove its high performance," says Dobersberger. During the pro - duction of glass fibre-reinforced fab - ric, scrap is produced from the non- crimp fabric or also residual spools. The 100 percent glass fibres were fed into the recycling process with - out pre-shredding and compounded with polypropylene or other poly- mers. "In the tests, the recycled pel- lets produced showed higher me - chanical properties than the virgin material from well-known manufac- turers," emphasises Dobersberger. The PURE LOOP teamwill be avail- able for discussions at the Fakuma. Dobersberger invites all visitors: "We have a high level of problem- solving expertise and are happy to discuss even the most challenging issues. Please come and talk to us at the Fakuma." PURE LOOP GesmbH www.pureloop.at Fakuma: Booth A6-6314 Manfred Dobersberger, Managing Director of PURE LOOP, emphasises in the run-up to Fakuma: “Our ISEC evo is the perfect solution for injection moulders who want to return their production waste to the production cycle in high quality.” The integrated shredder extruder combination ISEC evo converts production waste into plastic regranulate that can be fed back into the production cycle The latest tests with an ISEC evo with 100 percent glass fibres were a complete success! The mechanical properties of the regranulates exceed those of virgin material from well-known manufacturers
