In the area of injection molding, we are concerned with sensors and actuators in injection molding tools, with demoulding behavior and with quality concepts for injection molding.
LowREEMotors - Rare earth reduction in high performance permanent magnet electric machines
Neodymium (Nd) magnets provide the highest torque densities to electric motors. However, Nd is considered a critical material for Europe because the demand will exceed the production in the following years and the production is not in Europe.
The LowREEMotors project aims at reducing the neodymium-dependence of Europe by developing magnets that will partially substitute some of the Nd for less critical materials like cerium (Ce). Ce substituted magnets have less magnetic performance than Nd magnets. Therefore electrical motors need to be redesigned to compensate for the new magnetic properties. The motor redesign will start from the alloy formulation, followed by shaping the magnet by powder injection moulding (PIM), all the way to modifications to the motor components.
LowREEMotors will develop permanent magnets with 10% less Nd and other rare earth elements (REE). The consortium will combine a strong expertise in machine design of Mondragon University and Valeo, as well as a full expertise in PIM feedstock development of Montanuniversitaet Leoben and magnet manufacturing of CEA, and Magneti Ljubljana. Katholieke Universiteit te Leuven will perform the life cycle assessment to determine the environmental impact of the new magnets and machines.

Acoustic sensor for injection molds
In-mold sensors are very useful for obtaining process information from injection molds. However, they are hardly used since they are often too expensive, the space in the tool is limited or they are simply not robust enough (wires in mold!). This is where the work at the Montanuniversitaet begins.
The Chair for Polymer Processing, in close collaboration with the Chair of Automation and the Industrial Liason Department (both Montanuniversitaet Leoben), has made the task of making in-mold sensors more robust and cost-effective in order to generate process information in order to define the switching point or to more efficiently compensate rotor systems in multi-cavity molds.
