Feddem presented its Fed 18 MTS twin-screw extruder at K2025. With the Fed 18 MTS, it


expands its extruder portfolio with an extra size. The labora- tory extruder is designed to meet the requirements of formulation and product development and enables precise, reproducible results in a small space. The modular design allows flexible adjust- ment of the process length from 32 L/D to up to 52 L/D – without changes to the frame, cooling system or control system. All supply lines are pluggable, dosing devices


are integrated into the extruder in a space-saving manner without additional racks and can be easily moved to the side for maintenance and cleaning, says the company. This allows the extruder to be quickly converted and used in many ways. Option- al add-on units such as the FSB side feeder or FSV side vacuum degassing provide practical scale-up options. � www.feddem.com

Gneuss offers technologies such as MRS extrusion systems, automatic screen changers and sensors for processing contaminated materials. Its Omni recycling machines are customisable and designed for high-demand applications. � www.gneuss.com


US-based Guill Tool says it has expanded its lab capabilities, which includes rheology instruments


in a facility focused on extrusion. The rheology lab measures the flow


characteristics of plastics to predict how a material will flow through its extrusion dies before production. Tooling geometry is optimised virtually, and the project can be viewed in 3D CAD. Machines here include a rotational rheometer, scanning calorim- eter, thermal conductivity meter and a new CT scanner. The rotational rheometer


generates viscoelastic data for polymer melts, precisely capturing polymer melt properties. Test temperature


ranges between ambient and 300°C. The lab’s scanning calorimeter characterises the thermal properties of a polymer sample, such as crystallisa- tion temperature, glass transition temperature and head capacity of the sample. Knowing these properties permits the simulation of shear heating and hot and cold spots in the flow area. The thermal conductivity meter determines thermal conductivity of the polymer sample across a range of temperatures. The new test extrusion facility includes two Killion 1.25in extruders, an RDN 2.0 PVS vacuum tank, a Keyence LS9000 dual axis laser gauge and two Dri Air ARID-X 10 30lb capacity dryers. The test lab allows single and co-extrusion capabilities with its die designs. � www.guill.com


Hellweg Maschinenbau has begun integrating an online flow measurement system called Smart Flow into its granulator products. It complements information already available via


Hellweg’s Smart Control system for bearing temperatures, speed and power consumption. Together, they provide a basis for Hellweg’s next step: integration of self-learning AI modules. These will calculate the optimum ratio between material properties, feed and required power during granulator operation. The control system will then independently regulate the machine parameters to maximise energy efficiency without human intervention. “The importance of the grinding process for suc-


cessful recycling is still far too often underestimat- ed,” said Mark Hellweg, managing director of Hellweg. The energy consumption of the granulators used for this purpose is not specified on the type plate. It is a free variable that can be adjusted to
