PVC profile processors, take note: the K 2010 tradeshow will be the official market launch of a new range of parallel twin-screw extruders, said to offer throughput increases of 25% above current machines, while also offering an improvement in energy efficiency.

The two formed battenfeld-cincinnati, with headquarters in both Bad Oeynhausen, Germany and in Vienna, Austria. For the K 2010 tradeshow, the company is presenting a model from this new, parallel twin-screw extruder series. Specially optimized mainly for PVC processing, company officials say it offers users a significant boost in output with a simultaneous increase in energy efficiency. Those battenfeld-cincinnati officials spoke this week during a pre-K 2010 event held in Düsseldorf, Germany.
The new machines, with a 34 L:D processing length, are fitted with screws sized from 78-135 mm in diameter. The four models of this series, which still awaits its own brand name, cover an output range from 100-1000 kg/hr in PVC profile extrusion, an increase in output by about 25% over the models previously offered by both companies.
This boost in performance was realized with the use of a four-shaft drive and by lengthening the processing unit. This drive unit, which the officials say is currently the most powerful on offer in combination with an AC motor, yields a high torque and consequently a high output. The machine's U configuration allows the drive block to be kept compact, so that the extruder requires no extra space in spite of its longer processing unit.
Thanks to the longer processing unit, a longer pre-heating zone helps ensure gentle material processing. As standard, the twin-screw extruders come with a metering device that is thermally separated from the filler, so that no additional water-cooling system is required. The screws are coated with molybdenum and the barrels are nitrided. A 19-inch touchscreen operating panel also is standard.
Walter Hader, who heads the manufacturer's Infrastructure division, said that eventually this twin-screw PVC extruder also would be adapted for pipe extrusion. —Matt Defosse
