Leistritz Extrusionstechnik GmbH showed the latest in co-rotating twin screw extrusion technology at K 2016 — and held a series of 15-minute lectures from industry experts throughout the show.
Topics included Industry 4.0, bioplastics, white and black masterbatch, conductive compounds, foam extrusion and halogen-free, designing screw geometries and flame-retardant cable compounds.
In machinery news, Leistritz presented its biggest twin-screw extruder — the ZSE 260 MAXX — using the help of 3-D glasses. The behemoth can process up to 35 metric tons of material an hour, depending on the application.
“We have installed a variable-speed drive here to guarantee a ‘spot on' economical mode of operation for large-scale compounding, particularly with fluctuating production requirements,” said Sven Wolf, managing director of Leistritz Extrusionstechnik in Nuremberg, Germany.
The big extruder has a very broad processing window, with a very good energy input, the company said.
In other news from K 2016, Leistritz presented the new ZSE 35 iMAXX for running masterbatches. That application requires quick product changes, and the twin-screw extruder was designed with closed, easy-to-clean surfaces and a stainless steel cover. The cooling/heating device is fully integrated into the frame. One central water connection is needed for the entire machine.
The company's U.S. unit, American Leistritz Extruder Corp., is based in Somerville, N.J.
