Feddem at Fakuma 2021: Extruder and its LFT pultrusion lines

The Sinzig based mechanical engineering company Feddem GmbH & Co. KG will provide an overview of its LFT pultrusion lines for the production of long glass fibre pellets as well as on the subject of upcycling and service in addition to its FED 43 MTS extruder at Fakuma 2021.

Feddem will be presenting a twin-screw extruder of the type FED 43 MTS 32 L/D. With a screw diameter of 43 mm and up to 142 kW drive power, this extruder size is ideal for pilot and production applications of small to medium batch sizes. The FED 43 MTS is equipped with FME mixing elements, kneading-block-free screw geometries, and modular, thermally insulated protective covers. The process length can be individually adapted by  an extension unit. The FSK strand head is equipped with swivel hinge.

"The technology of LFT pultrusion lines for the production of LFT-G long pellets has been around for several years. Feddem has taken a fresh look at the details of the line components to improve performance, quality and handling. The result is not only unprecedentedly tight tolerances from the fibre content in the pellets, but also the repeatability of the achievable material properties of the LFT compound on different lines and line sizes with haul-off speeds of up to 60 m/min," says Klaus Hojer, Business Development Manager at Feddem GmbH & Co. KG.

This was made possible, among other things, with a patented, modular impregnation tool. The extruder for melt preparation is installed parallel to the roving line, which allows considerable savings in the space required by the plant. All maintenance access points for the individual plant components have been designed to allow direct and fast access to ensure the highest possible plant availability.
