Neue Materialien Fürth GmbH

In the past, several research groups have made considerable efforts in developing a suitable casting process for short-fibre- and particle-reinforced materials (metal matrix composites – MMC) based on the incorporation of the reinforcing material by stirring with subsequent die casting. Various problems occured, however, such as the formation of agglomerates, settling of the reinforcing phases, the development of gas porosity and strong reactions between molten alloy and reinforcing phase.


Neue Materialien Fürth GmbH, started working on a new, better suited process chain. Several years ago, with the construction of a prototype magnesium extruder (compounder) for incorporating the reinforcing phase into magnesium alloys.

Within the publicly funded THIXOM project, the production route was further developed joining the extruder with a die casting unit to create a new, single-stage casting machine. This innovative direct compounding (DirCom-) process is intended to combine the benefits of injection molding and die casting.

Project partners were Volkswagen AG, Reiloy Metall GmbH, GK Concept GmbH and Druckguss Service Deutschland GmbH, as well as the Institute of Lightweight Engineering and Polymer Technology (ILK, TU Dresden) and the Helmholtz-Zentrum Geesthacht – Zentrum für Material- und Küstenforschung GmbH (Centre for Materials and Coastal Research).
