After goods inwards inspection, the raw materials (mainly iron oxide, barium carbonate respectively strontium carbonate) are weighed, blended, pre-sintered and ground to a fine powder with hexagonal crystals. For isotropic magnets, the prematerial is consequently granulated and pressed. There are two procedures in the production of anisotropic magnets. Firstly, the prematerial is dried and then pressed in a magnetic field. Secondly, the prematerial is wet pressed under the influence of a magnetic field; this is followed by sintering, finishing and cleaning. The surface can be machined, marked, magnetised or coated to customer requirements.
