Extrusion International 1-2023

19 Extrusion International 1/2023 Extrusion Tooling  Guill has introduced the latest generation of its Series 800, the 2-to-6 layer extrusion tooling designed to produce the highest quality, highest material-efficient 1/8” to 6” OD tubing for automotive, medical, appliance and indus- trial applications at MD&M in Los Angeles in February this year. The redesigned Series 800 produces flawlessly smooth extrusion and layer definition of Fluropolymer and other materials for all multi-layer, multi-lumen medical tubing, as well as fuel line constructions, multi-layer PEX pipe and drip irrigation applications, among others. The Guill de - sign further allows thin layer combinations of polymers and adhesives to .02mm or less. Guill offers its extensive line of crossheads and inline tubing dies in fixed and adjustable center, for single or co-extrusion applica- tions. The tooling is designed to process all compounds and features the company’s pat- ented, precision Feather Touch Concentricity adjustment, the Seal Right System, which com- bines with the Feather Touch system to eliminate polymer leaking. Guill also offers its unique spiral flow distribution system. All Guill tooling is produced with rigorous computer sim- ulation of the flow channels using Computational Fluid Dy - namics (CFD) programs, resulting in optimum uniform flow with no weld lines. Guill Tool & Engineering www.guill.com Fully Integration of Innovative Deinking Process for Printed Plastics into the Product Portfolio  KEYCYCLE, a subsidiary of the EREMA Group, has worked together intensively for two years with the Spanish company Cadel Deinking to further develop the innovative pro- cess of removing printing inks from the surface of plastic. This has proved successful, because there are now several deinking lines in operation at customers' sites, where they are proving their efficiency in processing printed inhouse and post industrial filmwaste. Having acquired the Cadel Deinking brand, KEYCYLE will now continue to develop the technology and market the deinking process un- der the KEYCYCLE Deinking brand. "We have already been exclusively responsible for the worldwide dis- tribution of this patented technol- ogy since January 2021, including the operation of the pilot plant to- gether with Cadel in Sant Vicente del Raspeig (Alicante). By acquiring the trademark rights, we are now tak- ing the final step of integrating this process technology into our product portfolio," says Michal Prochazka, Managing Director of KEYCYCLE. This technology is a milestone in safely feeding back into the produc- tion process recycled pellets made from plastics that were originally printed. "The product not only de - livers top quality, it now also meets industrial standards," explains Pro- chazka, referring to the new larger deinking line with a throughput of 1,200 kilo- grams per hour, an innova- tion that was presented for the first time at K 2022. With plants on this scale, the KEYCYCLE deinking pro- cess also opens the door to the post consumer recycling segment, where the removal of printing inks enables another significant quality upgrade for the recycled pellets. During the decolourisation pro- cess, the ink is dissolved from the sur- face of the shredded film or regrind material. Only water-based chemical components are used, which makes the deinking process particularly en- vironmentally friendly. The material is then fed into the recycling extrud- er. Of the eight plants ordered since the market launch, five are now in operation at customers' sites, where they are delivering very impressive results. The Cadel company continues to operate as Cadel Recycling Lab, dedi- cated to its core competence of devel- oping new innovative technologies for plastics recycling plus laboratory and software techniques for decon- tamination assessment.
