injection of magnets mainly pa and pps and other thermoplastic resin with ferrite and ndfeb magnetic powder, the material after mixing, mixing, granulation production pellets, and the use of injection molding machine for injection molding. according to the product production process to apply the orientation of the magnetic field or not, injection magnets are divided into isotropic injection magnets and anisotropic injection magnets.
more detailscompression of magnets is a reference to the powder metallurgy process, the preparation of bonded magnets process. the magnetic powder and magnetic powder in the proportion of mixing, granulation and forming and curing. press the surface of the magnet generally need to protect the coating, the general use of cathodic electrophoresis, spraying and other surface treatment process.
