TWIN SCREW EXTRUDERS | MACHINERY
Advances in twin screw extruder technology, including modularity and artificial intelligence, are enhancing performance, efficiency and precision. Chris Saunders reports on what’s new
Adding intelligence to extruder technology
The latest innovations in twin-screw extruder technol- ogy are reshaping the plastic industry by improving efficiency, flexibility, and the ability to process more complex materials and recyclate, enabling manufac- turers to meet ever-growing demands for high-quali- ty, cost-effective, and sustainable products. Energy reduction, modularity and use of artificial intelligence are among the features in new developments from machinery manufacturers. At Fakuma 2024 in Friedrichshafen, Germany,
KraussMaffei unveiled updates to its well-established BluePower line of twin-screw extruders, in particular the ZE 28. In response to customer requirements, new features include an improved head design which offers better protection of electrical parts and simplifies cleaning, a redesigned strand extrusion head, and a separated control cabinet. The standard version also adds two more optional positions for the operator panel, allowing the machine to be controlled from the left or right side.

outer-diameter-to-inner diameter (Do/Di) ratio of 1.65, an L/D ratio ranging from 32:1 to 64:1, and can add up to three side feeders. It is equipped with KraussMaffei’s processControl HMI software, which provides step-by-step instructions for various procedures, while common upstream and down- stream systems can be integrated. In addition, the ZE 28 BP combines advanced technologies and intelligent control systems to optimise energy consumption by up to 10% compared to conven- tional models. The company says: “In a world where sustainability and efficiency are high priorities, the ZE 28 BluePower presents itself as the ideal solution for companies that value environ- mentally friendly technologies.” Leistritz Extrusionstechnik launched its LinXX
controls at the Fakuma show, which can be used flexibly, from compact extruders to entire produc- tion lines. The company says the technology “offers
