Rare earth permanent magnets (RPMs) have revolutionized the performances and design of electric engines, alternators, hard disks and audio devices in the last 20 years through the progressive increase in the energy product allowing a sensible reduction of the size of magnets and an increase in their properties.

By combining EPoS’ electro-sinter-forging to commercial Nd-Fe-B melt spun ribbons magnet production becomes easy, lean, fast and low cost. Isotropic cylinders, rings, blocks and cubes can be produced directly with a single shot ESF whereas anisotropic shapes required a two step ESF:
