Above: KraussMaffei has updated its ZE 28 Blue- Power lab compounder, which now features it ppC control


to establish their products on the market and therefore keep their production volumes small,” says Simon Hill, Sales Engineer at Brabender. “The Big Compounder is particularly suitable for these companies because they need larger throughput volumes but want to keep their material costs at a low level.” The B-TSE-S 30/40 uses co-rotating screws


featuring a modular design and interchangeable screw elements. Various screw element geometries are available, depending on individual require- ments, and screws can be easily removed or swapped out. The machine also has a foldable liner system, giving the operator complete access during and after the extrusion operation, while the hinged design allows for easy cleaning.

BluePower update At the Fakuma international trade fair in Germany this year, KraussMaffei Extrusion showed the newest version of its ZE 28 BluePower laboratory extruder, which features high energy efficiency, good temperature control, improved surface cleaning, enhanced power electronics protection, and an optimised strand extrusion die. The company says


processing sections, includ- ing screw configurations, can be fully customised and all process-engineer- ing results can be scaled across the entire BluePow- er extruder range, which extends from size ZE 42 up to the ZE 186. The new model provides a

and high torque density (13.6 Nm/cm³). The processing section can be configured within a length range of 32 to 64 D and can be equipped with up to three side feeders, depending on the process task. Like other extruders in the ZE series, KraussMaffei says the ZE 28 BluePower is available in three material variants to provide the wear resistance and corrosion protection required for customer-specific applications. The ZE 28 BluePower is designed to support a wide variety of configuration options, including high-temperature processing section elements with thermal resistance of up to 420°C. In addition, the automatic screw removal towards the drive (Ultra- Glide) feature further expands versatility. Since October 2022, the standard version of all ZE BluePower extruders has been equipped with KraussMaffei’s pioneer processControl (ppC) system, which uses ‘wizards’ to provide the operator with step-by-step instructions for key procedures. “After intensive discussions with our customers, we have responded to current market require- ments and improved our twin-screw extruder accordingly,” says Michael Tieben, Product Man- ager for the ZE BluePower series at the company. The TM20 Hi-Tech co-rotating twin-screw


extruder from Italian company Maris, which celebrated its 60th


anniversary last year, has been


specifically designed and manufactured for laboratory applications. The company says it features the operational and performance charac- teristics typical of production equipment, so it can accurately reproduce the behaviour of materials on a reduced scale. One of the most interesting aspects of the TM20


Hi-Tech, the company says, is the level of flexibility, which allows fast changes of configuration de- pending on the raw materials used and the type of process required. This is achieved through the use of interchangeable and modular mechanical components, which do not need the input of specialised technicians. The machine is also very quiet, which is said to be an important benefit for use in a lab environment. The gearbox is lubricated using an oil bath, while barrel cooling is provided by a closed loop water


distributor, cools each part separately. � circuit which, starting from a main www.compoundingworld.com
