Bonded Ndfeb Magnets are plastic magnets made of fastened NdFeB magnetic powder.The molten NdFeB alloy flows to a high-speed rotating wheel under pressure, and cooled at a cooling rate of up to 106℃/ s, and then the formation of NdFeB boron ribbon, using striped powder to crumble into 200 microparticles, it can get fast quenching magnetic powder. And then after homogeneous mixing fast quenching the magnetic powder and binder, by die casting or injection molding made of die-casting magnets and injection molding magnets.Die-casting magnets used in the adhesive for the epoxy resin and injection molding magnets used for nylon. Injection molding magnets density is smaller than Die-cast magnets and its corresponding magnetic properties are also low.The size of the bonded magnets is high and the secondary processing is no longer required.Magnet surface by resin coating or nickel plating, can effectively improve its corrosion resistance. Thickness of Epoxy coating is about 10-25 microns, the surface is smooth, and it have gray and black two colors.
