Particle based processing and sintering

The spectrum of activities of the team comprehends the net-shaped manufacturing of parts via pressing technologies and powder injection molding of plastic feedstocks followed by debinding and sintering. Additionally, comprehensive technologies exist to sinter metal or ceramic powders with superposed pressure and/or electric field.

The team ”Particle based processing and sintering“ provides specific net-shaping and sintering technologies, which can be applied for metallic and ceramic powders. The equipment comprises on the one hand shaping technologies like powder presses, powder injection molding and tape casting (of metal powders), on the other hand specific sintering technologies, which enable the superposition of pressure (hot pressing HP) or superposition of pressure and electrical field (Field Assisted Sintering Technology FAST/Spark Plasma Sintering SPS, Sinter forging SF) during the sintering process.
