Cutting-off - Import export

The innovative precision-volume-dispenser eco-PEN700 made by ViscoTec offers a wide range of applications for low to medium-viscosity dispensing. preeflow® eco-PEN is a rotating and perfectly pressure-tight displacement system. Self-sealing rotor/stator design. Conveyance action by medium displacement in the stator through controlled rotor rotation. Safe conveyance without any modification of the medium. With its suck back option, preeflow® ensures clean and controlled material or medium cut-off while preventing post-dripping effects.

Metzner has developed the mandrel cutting machines of the SR series for cutting off sealing rings from injection-moulded or extruded tubes with different diameters. These machines are characterised by their unique processing method and high cutting quality. First, pre-extended "rubber tubes" are clamped onto mandrels. Due to the special design of the mandrels, the mandrel can be set up and removed quickly and without special previous knowledge. The mandrels are then automatically clamped in the machine between rotating spindles and production is started. A knife carriage travels along the tubes and cuts the flat sealing rings to the desired length with either push-fit or circular knives, depending on the requirements. This cutting method is particularly impressive with its high cutting quality in combination with a high output.

Technical information When machining bar material particular care should be taken that as little material as possible is removed as cutting forces should be minimised and costs reduced. Therefore the exchangeable disc should be selected as a function of the work-piece which is to be parted. Tool systems Das RC-System und S-System sollte als erste Wahl bei den Abstechbearbeitungen verwendet werden. Die Schneidplatten wurden so gestaltet, damit der Span schmäler als die abzustechende Nut ist und ein optimaler Spanablauf gewährleistet werden kann. Das Z-CUT-DUO System ist bedingt durch die Doppelschneidplatte auf eine bestimmte Stechtiefe begrenzt.
