Chief engineers of the polymer departments met invited by Dr. Martin Schäfers, chief engineer of Polymer Engineering Paderborn, KTP. “At the meeting we used the possibility to present our research activities and to further the networking”, says Schäfers.

Final meeting of the joint research project REX 11 / PSI 9
The staff of Polymer Engineering Paderborn, department of engineering, have worked on software programs which make the behavior of machines predictable. Experts from all over the world work with these simulation programs. They met in Paderborn to discuss current developments.
REX 11 and PSI 9 are the names of the current versions of the software which make the procedural design of single screw extruders possible.

The polymer lab (K-Lab), application-oriented research laboratory of the polymer technicians and interface between university and companies has put into operation an all-electric injection molding machine made by Engel. Prof. Dr.-Ing. Elmar Moritzer, polymer technology, and the COE of the K-Lab, Dipl.-Ing. Rainer Kleeschulte are very happy about it. The “Engel E-Motion 200/100” is used for a third-party project in which polymer recipes shall be made more efficient. Moritzer: “Individual polymer products which are produced in increasingly less numbers call for individual polymer compounds.

From 27th October to 3rd November Polymer Engineering Paderborn presented itself at the K2010 in Düsseldorf. The visitors were informed about research and teachings. At the fair stand visitors learned about the three great research and development agendas of Polymer Engineering Paderborn: Injection molding, joining and extrusion. The team working with Prof. Dr.-Ing. Elmar Moritzer (middle) used the K trade fair to maintain and establish contacts.

Within the scope of the research project for the process analysis or rather optimization of WPC-compounding (Wood-Plastic-Composites) a laboratory underwater pelletizing system was purchased. With the available strand plant pelletizing was not possible at high filling degrees because of strand tears. Using a hot die face pelletizing also had its limit as with WPC with low filling degrees on PP-matrix the pellets bonded. With the new underwater pelletizing now all compound formulations can be homogeneously pelletized.
