46 Extrusion International 4/2021 SHEET EXTRUSION High Performance and Quality for White Goods Multi-Touch roll stack Originally developed for high-tech applications, it now also conquers standard segments: the multi-touch roll stack for sheet and board production frombattenfeld-cincinnati Germany GmbH based in Bad Oeynhausen. In fact, the roll stack creates ideal cooling conditions thanks to its special process technology concept, and thus delivers high-quality semi- fi nished products, and all of this with narrow thickness tolerances and high line speeds, too. After the sheet industry, more andmore board production customers now also rely on the modern roll stack. One of these is the Turkish Vestel A.S. Group headquartered inManisa, which recently purchased a complete 2-layer line for Vestel Home Appliances Refrigerator Factories to produce HIPS boards. In addition to the multi-touch roll stack, the core competencies of this line include three high-speed extruders, which provide its enormous output of up to 3,000 kg/h
