European project REProMag

Resource Efficient Production of Rare Earth Magnets

The overall objective of the REProMag project was to develop and validate an innovative, resource-efficient manufacturing route (SDS process) for Rare Earth magnets that allows for the economically efficient production of net-shape magnetic parts with complex structures and geometries, while being 100% waste-free along the whole manufacturing chain.

The new Shaping, Debinding and Sintering (SDS) process for Rare Earth magnets is an innovative automated manufacturing route to realize complex 3D- and multilayered parts; resulting in a significant increase in the material efficiency of at least 30% during manufacturing; while at the same time allowing additional geometrical features such as threads, cooling channels, small laminations/segments (e.g. to increase the efficiency of electrical motors) and structural optimizations such as lightweight-structures or the joint-free realization of e.g. fins or fixtures that are either not possible with conventional manufacturing technologies or would lead to a significant additional increase of waste material during machining.

The REProMag consortium consisted out of 14 partners (companies and research institutes) out of 5 European countries. They provided an excellent coverage in terms of industrial and scientific competences and expertise.

REProMag was coordinated by OBE - Ohnmacht & Baumgärtner GmbH & Co, a SME located at Ispringen, Baden-Württemberg. Steinbeis 2i GmbH was as a project partner responsible for the project and knowledge management and dissemination and exploitation activities. It has supported the project bidding process as well as the contract negotiations with the EU. REProMag was funded by Horizon 2020 (Grant Agreement Nr. 636881).
