This product is mainly used in automobile door lock, in addition, it is also used in brushless motor, sensor, fuel meter and other fields.
This product is a permanent magnet made of Nd-Fe-B material for injection molding. The material is easy to be processed into thin-walled rings, rods, sheets and various special and complex shapes. It can make the magnet and other metal inserts (gears, screws, special-shaped holes, etc.) molded at one time, and is not easy to crack and fracture. The magnet does not need cutting and other mechanical processing, and has good surface magnetic field consistency and strong corrosion resistance.
The complete combination of injecting process and high-property rare-earth powder makes it possible to form an easily strong bonded Ndfeb ring magnet for the speaker. Our factory owes complete industrial chain from raw material blank, cutting, electroplating, and standard packing. If you need technical support about magnets, we could offer a one-stop magnet solution with high efficiency.
Bonded neodymium magnets are isotropic and have the advantage of more advanced shapes compared to sintered magnets. The magnet needs to be coated with a layer of black or grey epoxy or parylene to protect them against corrosion. Our factory delivers high cost-effective magnetic parts to various parts of the world with technology developed through many years of experience. Please feel free to contact us if you have any problems with your existing magnetic parts. Hall Induction Injection Molded Magnetic Encoder Ring
The Hot-pressed NdFeB magnets divided into two types, Hot pressed isotropic NdFeB (MQ2) and hot -extruded anisotropic NdFeb magnet (MQ3). The Hot-pressed isotropic NdFeb magnet is produced by rapid quenched NdFeB magnetic pwder under high temperature through compression. The hot-pressed anisotropic NdFeB magnet is mainly anisotropic radially-oriented ring magnet which is produced through compression and extrusion deformation by rapidly quenched NdFeB magnetic powder under high temperature.
Bonded NdFeB magnets are produced by mixing plastic binders with NdFeB powder, a process which allows the merging of high rare earth performances and bonded magnets potentialities. Injection Mould Ferrite Automobile Turbocharged Rotor Magnet
The process of obtaining this NdFeB powder was developed in the same time with the development of sintered NdFeB process. However, only during the last years, it started to experience an increased market growth, mainly thanks to the high variety of shapes, geometries, and material combination it can allow, by mean of compression and injection moulding.
There are many advantages which help minimize the assembling processes of a complete device as well as in its miniaturization. Furthermore, parts can also be moulded with high accuracy, reducing global tolerance of final parts. Also, the magnetization of the permanent bonded or plastic coated magnet can be obtained in a wide variety of configurations. We find these magnets applied in a wide range of products such as:
electric motors (rotating and linear)
