Windmöller & Hölscher: New Multi-Layer Die
The new MAXICONE multi-layer die for 5–7 layers marks an absolutely novel W&H blown film die design for the production of large width barrier films or polyolefine multi-layer structures. Available with die diameters from 350 to 500 mm, the MAXICONE is suitable for working widths from 1600 to 2200mm. Its compact design ensures very short melt flow paths and reduced melt residence times, which in turn result in minimum amounts of melt inside the die. The arrangement and shape of the melt channels and the spiral mandrel distributors guarantee optimal melt distribution inside the die, which also reflect in excellent purge properties and very tight basic tolerances. The newly designed MULTINIP system represents a valuable addition to W&H’s range of haul-off systems. The MULTINIP is characterised by a very long tube collapsing section, direct driven turning bars and a vibration free suspension system. The new haul-off features maintenance free components and uses a CAN bus system for maximum functional and operational reliability.
