TWIN SCREW EXTRUDERS | TECHNOLOGY


Adaptability and sustainability underpin the latest developments in twin-screw extruders used by compounding and recycling companies. Chris Saunders reports


Technology groups update extruder abilities


Major machinery companies in the twin-screw extrusion sector have been active in launching new technologies, upgrading established systems and adding features to enable compounders meet the varying challenges they face. Advances in screw geometry, torque and process control enable compounders to handle increasingly challenging polymers from heavily filled engineering plastics to composite materials incorporating glass fibre or functional fillers. An important recent development has involved the roll-out of twin-screw extrusion technology for plastics recycling operations. At PlastAsia 2025 in Bangalore, India, Steer


World launched the iSeries, its latest twin-screw extruder line which has been developed specifi- cally for emerging players in India’s plastics industry, delivering optimised cost performance, reliability, seamless upstream and downstream integration, and accelerated speed to market. Drawing inspiration from the company’s Mega and Omega platforms, the iSeries offers standardised solutions tailored for general-purpose applications

and seeks to bridge a crucial gap in the com- pounding ecosystem by providing affordable, high-performance systems that support increasing demand for plastics processing in automotive, infrastructure, consumer goods, and packaging. “With the launch of the iSeries, we are redefining the benchmarks for accessible innovation in plastics compounding,” said Sunil Dutt, Vice President of Sales. “This platform embodies our commitment to empowering value compounders with smart, scalable and reliable technologies, bringing the power of high-performance compounding to the heart of India’s manufacturing landscape.” Among the technologies on display at CPM’s


booth at K2025 in Dusseldorf, Germany, was an example of its Global Extrusion Technology (GXT) in the form of a powerful plug-and-play twin-screw extruder designed for high throughput, energy efficiency, and precise process control. Available in standard centreline geometries, the GXT features a torque density of 13 Nm/cm³ and is configurable in length-to-diameter (L/D) ratios from 40 to 48,
