Chemnitz TU extends its machinery for mass-oriented plastics processing
Further research into natural fibre compounds
The ZIL is a competence centre and research partner for small and medium-sized plastics processing companies. Its research and development activities are focussed on new combined injection moulding processes for plastics reinforced with long-fibre materials and semi-finished textile products. These materials are used for constructional elements in the automotive and aircraft industries as well as for railway vehicles, where they help to reduce weight and thus carbon dioxide emissions.

With an output capacity between 50 and 250 kg/h, the new ZE 40 A x 50 D UTXi twin-screw extruder from KraussMaffei Berstorff enables the scientists in the team of Dr. Wolfgang Kemp, head of the extrusion technologies department at Chemnitz TU, to carry out development work as well as small-batch production for further processing. The machine offers outstanding technical features. The combination of rectangular barrel sections with highly efficient evaporation cooling provides optimum temperature control. The patented C-clamp system gives rapid barrel replacement and the wide range of available barrel sections and screw elements offers unparalleled flexibility. Thanks to the inside/outside diameter ratio of 1.46, which ensures an optimum intake volume/torque relation and speeds of up 1,200 rpm, the ZE is also ideal for high-performance compounding tasks. The 50 D processing section length is suited for variable addition of additives, which is of particular importance when processing extremely sensitive long fibres.
“We are happy that an additional extruder of our proven ZE-UTX series has made its way into a research institute. Basic research is decisive for us as a mechanical engineering company as it offers the opportunity to tailor our extruders to market requirements and to continuously improve their design”, explains Gerhard Schmitt, sales manager for twin-screw extruders in German-speaking countries at KraussMaffei Berstorff.
