Extrusion International USA 5-2021

PREVIEW 56 Extrusion International 5/2021 FEDDEM is pleased to be able to pro- vide an overview of its LFT pultrusion lines for the production of long glass fi bre pellets as well as on the subject of upcycling and service in addition to its FED 43 MTS extruder at Fakuma 2021. The company will be presenting a twin-screw extruder of the type FED 43 MTS 32 L/D. With a screw diame- ter 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 model range offers all the typical FEDDEM advantages that are of great bene fi t in com- pounding and masterbatch applica- tions: • Highly ef fi cient melting and mixing of product components through the use of FME mixing elements. Knead- ing-block-free screw geometries prove their worth in a wide range of applications. • Modular, thermally insulated pro- tective covers of the processing sec- tion as protection against contact and for a more favourable energy balance of the process. • Process length can be individually adapted by extension unit • FSB side feed(s), FSV side vacuum deaeration, FSE side vent(s) each with quick connections (mechanical, elec- trical and, if applicable, for cooling water connections). • FSK strand head, compact and equipped with swivel hinge. On re- quest, also available with patented arched nozzle for special applica- tions. • Robust design of all system compo- nents for continuous operation. “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 un- precedentedly tight tolerances from the fi bre content in the pellets, but also the repeatability of the achiev- able 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 oth- er things, with a patented, modular impregnation tool. The extruder for melt preparation is installed paral- lel to the roving line, which allows considerable savings in the space re- quired by the plant.
