K2022 | EXHIBITION REVIEW
Right: This rugged PA6 battery casing demonstrator has been
developed by Lanxess and Kautex Textron and is now at the trial stage
single-screw extruder is installed in a piggyback position directly over the injection unit of an otherwise standard hydraulic injection moulding machine and the compounded melt is conveyed directly into the plasticising unit. The compounding extruder operates intermittently and the one-step process is claimed to trim energy consumption and reduce CO2
footprint.
At the K show, a DCIM unit was shown on an 1,100 tonne GX 1100-4300 injection press produc- ing a five-piece polyolefin collapsible crate on a 35s cycle using three scrap materials with different viscosities — a PP staple fibre fleece from masks, a shredded HDPE material used in packaging and HDPE blow moulding scraps from toy production — plus masterbatch, stabiliser additives and micaceous iron oxide. �

Lanxess launched Emerald Innovation NH 500, a new phosphorus flame retardant for engineering plastics claimed to provide high thermal stability with minimal impact on mechanical properties. Designed primarily for use in glass fibre-rein-
forced plastics for electrical and electronics applications, the new flame retardant allows a UL94 V-0 rating at 0.8m to be achieved in glass rein- forced PA66. Glow-wire tests show a flammability Index (GWFI) of 960 °C at 3mm thickness. The company also showed a new EV battery
enclosure concept developed in PA6 in conjunc- tion with Kautex Textron. The “near-series” part measures 1,400mm by 1,400mm and is said to pass all mechanical and thermal tests. A prototype is currently being road tested to verify its suitability for daily use. According to Lanxess, the carbon footprint of the plastic enclosure is more than 40% less than an aluminum design. The part is compression moulded in a com- pound based on Durethan B24CMH2.0. Crash- relevant areas are reinforced with locally placed

Maag filled its stand at K with new and updated products from across it businesses. For strand pelletising, the company launched the Primo SI, an updated version of its Primo S with a more open base frame for improved accessibility. The entire cutting head now sits on four vibration dampers and beneath a revised acoustic hood for reduced noise levels. The pelletiser now also boasts Bluetooth connectivity. Underwater pelletiser developments included the new Pearlo XXL high-capacity systems aimed at polyolefin and large-scale engineering plastics applications with production rates up to 80 tonnes/ hour. Special attention has been paid to the water flow, with one tangential inlet and one through the cutter hub – the balance between the two can be adjusted to optimise production. The design ensures that all pellets have a similar residence time in the cutting chamber, while the latter’s asymmetric two-piece housing has been designed to provide easy access and start-up. The new Pearlo XXL takes advantage of die-plate technology from AMN, the French company that Maag acquired in May this year. At K it showed a 1500mm diameter die-plate with a central water injection system designed to improve pellet cooling and ejection. The company said the Central Injection System (CIS) is
particularly suited to the high-volume
pelletising of high-melt-index materials. Maag also used the K show to present its
