Extrusion International 5-2023

34 Extrusion International 5/2023 FAKUMA 2023 Progress in Machinery Technology and Service The machinery builder FEDDEM is displaying develop- ments in its extrusion and compounding equipment at this year's FAKUMA. At its booth, FEDDEM presents the latest version of its proven FED 43 MTS extruder and accessories.The ex- hibit boasts the following features: • The FED 43 MTS extruder is now available with up to 157 kW of drive power. The processing length of the displayed extruder is seen in its base length of 32 L/D. There is the option to expand the extruder with attach- able extensions in various lengths. A 10 L/D extension is highlighted at the exhibition. In a production environ- ment the transition between 32 L/D and 42 L/D process- ing length can be completed in about two hours. • For reliable introduction of liquids into the com- pounding process multiple ports can be made available on the extruder's processing section. At the exhibit, a nozzle is installed after the melting zone. • The latest version of the vacuum-assisted side feed- ing unit, FSB-V, is now equipped with a viewing win - dow. This allows for direct observation of flow patterns within the device during processing lightweight fillers and expedites adjustments of device parameters for op- timisation. Additionally, conventional FSB side feeding and FSV side vacuum degassing units can be attached to the pro- cessing section as required. In the maintenance sector, the popular double-brush cleaning unit, Type FRE, which is designed for cleaning figure-8-shaped barrel bores, is now available with a modular shaft, allowing for on-site adjustment of the device's length. "In the pursuit of sustainability in compound produc - tion, a seamlessly continuous production is quickly rec - ognized as one of the most critical prerequisites for ef- ficient production," says Lars Mansfeld, Team Leader for Assembly & Service at FEDDEM. "To minimise unplanned production stoppages, FEDDEMnowoffers tiered service packages, ranging from simple wear condition measure - ments of barrels and screws to tailored maintenance plans specific to the individual line configuration." The Sinzig-based company also offers LFT pultru- sion lines for producing LFT-G pellets (Long Fiber Ther- moplastic-Granules). According to their own claims, FEDDEM's equipment excels in terms of performance, quality, and ease of use in conventional short-fibre com - pounding processes. For instance, alongside unparal - leled narrow tolerances of fibre content in the pellets, the repeatability of achievable material properties of the LFT compound is achieved when using various pro- duction line sizes at strand speeds of up to 60 m/min. The use of a patented modular impregnation tool plays a crucial role in this context. "Our extruder for melt preparation is positioned parallel to the roving line, allowing significant space savings in the plant lay - out. FEDDEM pultrusion lines require only slightly more floor space than a conventional compounding line of similar throughput. All maintenance access points for individual line components are designed to provide di- rect and fast access, ensuring maximum line availability in case access is required," explains David Constroffer, Head of Project Management.
