TECHNOLOGY | MACHINERY JOINING Raising performance in pipe fusion
McElroy has introduced its new TracStar iSeries, which it says will bring a new level of performance and reliability to pipe fusion. The three models in the series maintain the TracStar’s rugged, self-contained tracked vehicle while adding new features, says the company. “The iSeries is an evolution
inspired by the feedback we have received from those on the front lines of fusion,” said Geoff Koch, vice president of product development at McElroy. “We believe this will move the fusible pipe industry forward in the water, mining and natural gas distribution sectors.” The iSeries is powered by the new

over MTI Zeppelin Systems of Germany is the new owner of MTI Mischtechnik, which became insolvent in October last year. The MTI portfolio includes heating, cooling and universal mixers for plastics processing and chemical applications. “Since the mixer solutions from MTI and Zeppelin are largely used in different industries, the overlap of the portfolio is small,” said Rochus Hofmann, managing direc- tor of Zeppelin Systems. The former MTI team will continue to be based at the company’s site in Detmold. �

Update simulates cooling and distortion of polymer extrudate
PlasticFlow has developed a new version of its PolyXtrue simulation software, that accurately models extrudate cooling and extrudate shrinkage in the complete cooling system. The update can handle up to 20 calibrators and sizers in the cooling system. Two different temperature zones are allowed between calibrators. One of the two temperature zones can be a wiper between a water tank and the next calibrator. At the same time, 10
different temperature zones are allowed between the die exit and the first calibrator, and

10 different temperature zones are allowed after the last calibrator. By gradually changing the shape of the profile in subsequent calibrators, the shape of the extrudate profile can be significantly modified after it leaves the die – allowing extrusion of complex profiles from relatively simple die geometries. The new version allows die geometries to
be imported in native Creo file format. Geometries in SolidWorks and Inventor file formats can be imported as before, according to the company. �

cover three size ranges from 8in IPS to 48in OD (225mm-1200mm). All are equipped with a new, quieter engine that meets US Tier 4 and EU Stage V environmental regulations while providing greater torque. The system pressure was raised to more than 3,000 psi for more powerful ground drive, pipe lifts and other functions that use higher levels of pressure. �
