SHOW PREVIEW | FAKUMA 2018
Right: Maag will present its Extrex X6
high
performance gear pump at Fakuma
reduce part weight by up to 30% while maintaining most of the original mechanical proper- ties, the company claims. It says foamed components produced with the system exhibit a performance factor for bending stress in the range from 1 to 1.3, meaning the change in flexural strength is less than the reduction in weight. In addition to the weight
saving, the PA-optimised endother- mic blowing agent enables sink marks and shrinkage cavities to be avoided. Delami- nation in components subject to high mechanical stress, which may arise during the addition of masterbatch based on polyethylene or universal carriers, is reduced or prevented by the use of a PA carrier system. Luvobatch PA BA 1001/1002 can be used in all common processing techniques. Lehvoss will also show its Luvosint and Luvocom
3F products for 3D printing, its Luvotech line of technical compounds, and Luvocom P powders for electrostatic coating. �

Maag’s display at Fakuma includes the Extrex X6 class gear pump, which is designed for particularly high melt pressures and is suitable for operation over a wide range of viscosities, and Primo 200 and Pearlo 160 pelletisers. The company says that the X6
gear pump
features a completely updated design, from the gears and shafts to the bearings and seals. It says the unit has been optimised to ensure maximum product quality, volumetric efficiency and consist- ency of the production process. The Primo 200 E model pelletiser at the show is
an example from Maag’s WSG dry-cut range and is said to be suitable for reliable production of

high-quality cylindrical pellets or micro-pellets. It features a variable system configuration for processing of soft, brittle or abrasive polymers while a fast tool and
roller exchange facility enables optimum flexibility for product changes. With a 200 mm draw-in width, The Primo 200 E is designed for
draw-in speeds up to 120 m/min and a maximum throughput rate of
1500 kg/h.
The Pearlo range of underwater pelletising systems will be represented with a Pearlo 160 model. Combining the best technologies from Maag’s Gala and Automatik divisions, it achieves throughputs of 1,000 kg/h to 6,000 kg/h. Pearlo models are characterised by a small footprint while the electronically controlled EAC technology ensures precise positioning of the pelletising knives during operation, ensuring long runtimes and consistently high pellet quality. �

Nordson will introduce a new line of screen packs for its BKG series of screenchangers that are claimed to withstand higher pressures and offer longer lifetimes. The new screen packs feature a robust multi- layer structure that is said to prevents failures caused by the pressure differentials of up to 200bar encountered during filtration. It is particu- larly effective at preventing “screen dimpling” where screen layers are forced into the holes of the breaker plate, breaking the peripheral seal and allowing contaminants to bypass the filter. “The new Nordson screen pack design main- tains structural integrity while efficiently filtering out contaminants and ensuring optimal melt permeability,” says Christian Schroeder, Global Product Manager Melt Delivery Systems. “As a result, our screen pack yields more output between screen changes than screen packs offered as low-cost alternatives, increasing the productivity of the extrusion line and enhancing profitability.” The new packs are supplied with different layer
combinations to suit customer requirements. However, a typical structure would include four layers - two coarse square-weave layers outer components, one fine square-weave fine filtration layer and a high permeability Dutch weave fine filtration layer. �
