For most bonded magnet manufacturers, anisotropic neodymium granular used to produce injection magnet, the technology is much lower threshold. Because the use of injection molding anisotropic bonded ferrite manufacturing technology is very mature, and its principle is the same as that in the granular injected into a mold when the magnetic field increases, so magnetic powder in the molten state of polymer in the direction along the magnetic field orientation.

There are two types of magnetic field orientation, the permanent magnetic field and the pulsed magnetic field. The permanent magnetic field orientation of lower-cost mould for injection molding machine there are no special requirements, that ' s for the radial orientation of the magnets, but the magnetic field strength is not high; the pulsed magnetic field need the injection machine with excitation power and the coil to generate pulsed magnetic fields, equipment cost is high. Suitable for the radial direction and axial direction of the magnet, the magnetic field strength is high
