Extrusion International 5-2024

47 Extrusion International 5/2024 Focus on Innovative Technologies and New Products F EDDEM is once again exhibiting at this year's Faku - ma and will be presenting its latest developments. In addition to its tried-and-tested extruder models, the company will be focussing on the expansion of its port - folio, new developments in peripheral technology and pioneering augmented reality applications. FEDDEMwill be presenting the latest model of the FED 26 MTS twin-screw extruder with additional aggregates (see picture 1) at its stand, as a production machine for small quantities or for use as a pilot plant extruder. The exhibit is equipped with the following accessories: • Extruder with 32 L/D and a 10 L/D extension module, 34 kW installed drive power and max. screw speed of 1200 rpm. • FSB side feeder • FSV vacuum side degassing unit • FSK extrusion head with FEDDEM's patented sheet die plate In addition to the FED 26 MTS, FEDDEM is expanding its portfoliowith the new FED 18MTS extruder. This com- pact extruder is more than just a new size. It is specially designed to meet the requirements of a laboratory ex - truder and thus offers customers an optimum solution for formulation and product development in the well- known FEDDEM quality. “The FED 18 MTS represents our continuous further de - velopment in the field of extrusion technology. With its modular design, it is designed to meet the special require - ments of our customers in terms of flexibility and user- friendliness and to help them optimise their production processes in an efficient and resource-saving manner,” says David Constroffer, Head of Engineering at FEDDEM. Another innovation on the stand is the FEDDEM Auto- matic AirBlade (see pictures 2 and 3). This product inno - vation was developed to minimise the frequent problem of beard formation in twin-screw extrusion. Bearding oc - curs when thermoplastic material or filler accumulates at the die outlet of the extruder and hardens. In the case of complex compounds with a high filler content, this can lead to strand breaks without suitable countermeasures, which can significantly impair both productivity and the throughput rate. In addition, residues that adhere to the polymer strand can have a significant impact on the opti - cal and mechanical quality of the end product. The FAA offers an efficient solution to this problem by removing residues with a targeted stream of hot air. “The FAA was developed in close collaboration with one of our customers and tested under real production conditions,” reports David Constroffer. “This product innovation effectively minimises the negative effects of product residues at the nozzle outlet and thus ensures improved productivity and product quality.” According to the manufacturer, a special feature of the FAA is the patent-pending deflection mechanism, which sets it apart from conventional solutions. This mechanism ensures that the slot die is automatically retracted from the operator's working area as soon as a strand breakage occurs. This function is designed not only to protect the operator, but also to ensure a smooth production process by minimising potential disruptions in the process. “With this innovative deflec - tion mechanism, we offer a solution that significantly improves both safety and efficiency,” emphasises David Constroffer. “The FAA rep - resents a significant im - provement over conven- tional methods and fulfils the highest requirements of our customers.” In addition to the trade fair highlights, FEDDEM is pleased to announce the commissioning of its new pilot plant line. In the tech- nical centre, customers have the opportunity to carry out tests on a wear- protected FED 43 MTS Picture 1: FED 26 MTS with additional unit (All pictures: copyright FEDDEM GmbH & Co.
