which, starting from a main distributor, cools each part of the barrel individually and is heated electrically. UK-based company Xtrutech, which designs and manufactures extrusion equipment, has introduced the XTSXP-19, a compact co-rotating twin-screw extruder designed to deliver high-torque, high-shear compounding performance in a laboratory or pilot-scale setting. Retaining the company’s signature clamshell barrel design, the XTSXP-19 offers rapid access to screws and liners for cleaning and reconfiguration, considered a key advantage for development environments running multiple formula- tions in quick succession. The modular screw and barrel sections allow flexibility in


L/D ratios from 24 to 54, enabling precise control of shear and residence time and at the heart of the system is a 7.8 kW drive delivering 1,200 rpm screw speed and up to 31 Nm torque per shaft. Combined with advanced barrel heating and cooling zones, the XTSXP-19 can replicate the demanding thermal and mechanical conditions of larger production extruders while a touchscreen PLC control system ensures easy process monitoring and repeatability. The unit was primarily developed for highly-filled and high-viscosity formulations that typically demand larger extruders, and is ideally suited for mineral- and glass-filled engineering plastics, colour and additive masterbatches, reac- tive and devolatilisation compounding, and trials involving bio-based polymers/foams or recycled materials. The enhanced torque capacity ensures efficient dispersion and homogenisation of viscous, fibre- or filler-loaded compounds, while maintaining stable processing conditions across a wide range of materials, which the company says makes it ideal for formulators and R&D teams who require production-level compounding capability without full-scale equipment.


Redesigned KraussMaffei has updated its BluePower series with a completely redesigned ZE 28 BluePower laboratory extruder, combining the company’s signature engineering expertise with a clear focus on customer needs. With faster availability and improved user-friendliness, the company claims the new model sets a fresh benchmark in laboratory- scale extrusion. The ZE 28 BluePower was designed to achieve a balance between free volume (OD/ID = 1.65) and a torque density of 13.6 Nm/cm³, a combination which allows for excellent compounding performance and flexibility across a wide range of materials and processes, the company said. Depending on application needs, the processing section can be configured between 32 and 64 D and equipped with up to three side feeders or degassing units. To handle everything from standard polymers to highly filled or corrosive compounds, the extruder is offered in three material variants, ensuring the right level of wear and corrosion protection for every task. In keeping with current trends, the ZE 28 BluePower has
