Extrusion International 6-2019

63 Extrusion International 6/2019 FilmDivision The film technology division of Hoso- kawa Alpine, one of the leading suppli- ers in the field of process engineering and blown film extrusion, is presenting its latest developments and current components for efficient film produc- tion at interplastica 2020 inMoscow. The plastics sector faces major chal- lenges in view of the increasing de- mands for efficient use of energy and resources and high standards of quality for flexible packaging. As a technologi- cal pioneer, Hosokawa Alpine offers a wide range of appropriate solutions for future-proof system configura- tions. The new HX Select extruder se- ries, for example, features an innova- tive cylinder and screw design for up to 50 per cent higher output, with at the same time an energy saving of up to 20 per cent versus standard barrel extruders. Another highlight present- ed by Hosokawa Alpine is a complete cooling system, consisting of the new Alpine CRX cooling ring series for outer cooling as well as the also new Alpine HT cooling tower for inner cooling. The low-counterpressure system achieves energy-efficient use of existing cool- ing capacity and guarantees optimum filmqualitywithmaximumoutput. The Alpine ASWscreen changer will also be presented as an additional innovation. The screen changer developed by Ho- sokawa Alpine blends perfectly into Al- pine systems and makes for maximum efficiency. The new Alpine HWD wind- er ensures perfectly wound films. The latest-generation winder combines the advantages of flatbed and turret nection of the stator knives as well as a solid and efficient cast rotor. “Besides a sharp cut, our patented cross-scissor- cut rotor guarantees a verifiably re- duced energy consumption of as much as 20 per cent compared with conven- tional cutting techniques,” underlines Bernd Kneisl, Operations Director of the Recycling & Granulators Division of Hosokawa Alpine’s process technol- ogy business segment. Above all when high cutting performance is called for, the Rotoplex granulator – as for exam- ple the exhibited 50/80 Ro – shows its true strength. Dependent on themate- rial and screen perforations, the granu- lator achieves throughput rates of up to 1000 kg/h. Over and above the high cutting pow- er, the Rotoplex 50/80 Ro has numer- ous other design features which guar- antee immediate benefits to users. Once the top section has been opened, the cutting chamber is easy to access. Whichmeans that cleaning procedures as well as knife or screen exchange are quick and uncomplicated. This serves to prevent long periods of downtime. In addition, the special shaft bearing prevents penetration of the product into the bearing as well as the ingress of excess lubricant into the cutting chamber. Film and Recycling Division in Focus winders in a single machine and allows high winding speeds with perfect film quality. The two digital tools, Hosoka- wa Alpine Isa and ExVis 5.0, round off the system portfolio. Hosokawa Alpine Isa is a central digitisation platform, developed from scratch, that can read out, save, display and analyse process data from the widest range of plant types. The update to version 5.0 gives the tried and trusted ExVis process vi- sualisation tool many additional new features, in addition to a more neatly structured and convenient user inter- face. This transforms ExVis into a fully networked system in which the data of all system components can be merged andmanaged. Recycling Division Among others, Hosokawa will present a robust high-performance granulator The efficient recycling of production wastewithin the frameworkof a closed material circuit is becoming increas- ingly important. Hosokawa Alpine sets standards here thanks to its decades of experience. The Rotoplex model from the granulator product line has proven itself to be particularly successful for the reliable size reduction of all kinds and shapes of plastic waste. This clas- sic granulator from Hosokawa Alpine is constantly refined and improved and makes its mark even in the current sev- enth generation by virtue of its reliabil- ity and top performance. The high-performance granulator is characterised by its robust design in high-grade spheroidal graphite cast iron inGGG40 quality, the positive con- HOSOKAWA ALPINE Aktiengesellschaft www.hosokawa-alpine.com interplastica 2020: Booth 02 2B15
