to 150 kg/h, depending on the material formulation. For example, Feddem says that the 26 MTS can process 50% glass-filled PA 66 at rates of 100 kg/h, 45% glass-filled PET at 90 kg/h, and POM at 80 kg/h. The company highlights the


versatility of the MTS line and its ability to process a wide range of formulations without changing the screw configuration. “This is a

Feddem extended its Multi-Task Standard (MTS) series of intermeshing, co-rotating twin-screw compounders with the launch of its smallest model at this year’s Fakuma show in Germany.


The FED 26 MTS unit is designed for lab-scale to


pilot production, and shares many design features with the four larger units in the series. The new unit has a 26.6 mm screw diameter with a 1.55 OD/ID ratio and typical barrel lengths of 32, 42 or 52D. The extruder can achieve processing temperatures up to 400o


C, and has


drive power of 28 KW and screw speeds up to 1200 rpm. The unit can be used for small batch processing for


material development, processing just 1 to 3 kg of material if required. Throughput rates range from 10 up


primary philosophy of the company, that a processor can handle a wide variety of different compound grades and recipes with one screw design, without having to open the machine or change the screw,” says Dieter Gross, Feddem’s managing director. “With this machine we have focused on the typical


masterbatch producer or compounder with a wide product portfolio that processes two or three formula- tions on a machine every day and requires changeover times as short as possible,” he adds. Feddem offers a multi- tasking screw design for a wide variety of different technical compounds, and a different multi-tasking screw design for a wide variety of different masterbatches.
