Molded Magne

The NdFeB magnetic powder and the binder are mixed according to a certain ratio, granulated and then pressed in a mold. The product has the following characteristics: 1) The product has high dimensional accuracy: it can meet the accuracy requirements in one molding, and generally does not require mechanical processing 2) Free formation of product shape: it can be made into rings, cylinders, discs, tiles, blocks and various-shaped magnets. 3) Excellent magnetic performance: The BH(max) is three times that of anisotropic ferrite. With high intrinsic coercivity, the product features simple production, short process, stable performance in batch production, 4) Flexible magnetization methods: the magnetization can be axial, radial, spokewise and skew magnetization etc 5) Good corrosion resistance and outstanding surface quality: The surface of the product is coated with epoxy resin that features excellent corrosion resistance.
