And uniform complex; strong magnet bonded magnet has the following characteristics has the advantages of simple process, process short, neodymium iron boron magnet product consistency is good, suitable for industrialized batch production, product size precision is high, the general does not require machining free form, the product can make thin-walled, shaped compartmentalization and tile, and other various shapes, properties of magnets, but also can be made into axial, radial and radial and multipole magnetized magnet; mechanical strength is good, the product is not easy to break, off edge off angle, regeneration and utilization of raw materials, thus to achieve the purpose of energy saving, electricity saving, saving raw materials, thereby reducing the cost; the magnet and the motor shaft and other parts of various molding. This not only ensures the high accuracy, reduces the overall system of tolerance, but also reduces the total cost. Because of the above characteristics, NdFeB bonded magnet is especially suitable for producing all kinds of small, precise motor. It is widely used in office automation, computer peripheral components, electronic and automotive industry.
