Extrusion 5-2018

... for Heavy Recycling and High Filtration Level s Cofit International presented an important innovation in the field of screen changers at Plast 2018, its most innovative model for recycling highly contaminated plastics: Gorillabelt T, an automatic and continuous screen changer for recycled materials with a high filtration level, up to 50 micron. T he plastic market is currently asking for more and more complex, faster, smarter, and better-quality solutions in extrusion plants. This involves optimizati- on of devices, materials, processes, and technologies. High-quality products can be obtained from cheap raw materials, thanks to refined processing and innova- 42 Periphery Extrusion 5/2018 Automatic and Continuous Screen Changer ... Cofit at Plast 2018 tive solutions in filtering and in screen changer technology. Due to the special Gorillabelt T screen changer technology and design, only dirt, impurities and plastics sticking onto the filtering screen surface are discarded. During cleaning, material loss is irrele- vant. Cofit International has designed and en- gineered Gorillabelt T – its most innovati- ve automatic and continuous screen changer for plastic – with the aim of guaranteeing a series of important ad- vantages for enhancing the performance of the production line as follows: • production of excellent quality materi- als with zero or extremely low levels of impurities; • use of smart raw materials, e.g. highly- contaminated post-consumer plastic, up to 10% of contamination level; • extrusion of most thermoplastics, in- cluding PET; • increase of output rates and automa- tion level, easily programmable and user friendly controls; • zero polymer loss during the cleaning cycle; • reduction of: personnel costs involved
