ARTEC and KraussMaffei Berstorff cooperates in recycling-compounding technology

The Austrian recycling-unit specialist ARTEC machinery GmbH, and the German producer of extrusion units, KraussMaffei Berstorff, concluded a cooperation agreement covering the technology portfolio “Recycling-Compounder Equipment”.

“With the new concept under the project name ‘Edelweiss’, consisting of the ARTEC preparation technology and the KraussMaffei Berstorff twin-screw extruder technology, material recycler and compounder factories will improve their added value by diversification and quality enhancement.” says Hagen Mosser, Technical Director of ARTEC.

Ralf J. Dahl, Division Manager, twin-screw-extruder of KraussMaffei Berstorff, adds the advantages of the system, “The Edelweiss technology enhances the energy-balance in the material flow. The main benefit of this solution is the possibility to produce high quality compound on ‘a single heat’. Not only energy savings are achieved, but also the shear-energy ratio in the plasticization, which is damaging the polymer structure, is being minimized – and therefore improving the material quality, since no repeated heating of the charge material is necessary due to procedure-integration.”

ARTEC is contributing the processing technology of material-cutting and compacting with dehumidifying potential, extrusion units with degasing systems and individually customized melt filtration units into the partnership. Meanwhile, KraussMaffei Berstorff offers comprehensive experience in compounding with twin-screw extruder, where the important part of the refinement processing of high-end compounds takes place.

Following the flexible plant concept, the ARTEC processing unit and the KraussMaffei Berstorff compounding unit can be operated combined as well as individually.

Mr. Mosser and Mr. Dahl conclude, “Together we can offer the ‘Edelweiss-unit Technology’ for throughput rates between 300-2,500kg/h. A trial unit for material testing and design/development of compound recipes is available. The new process technology and its potential will be presented for the first time at the K 2013 by both cooperation partners.”
