The magnetic property of bonded NdFeB is weaker than sintered NdFeB, but stronger than ferrite, and has high stability. Among the isotropic bonded magnets, this magnet has the strongest magnetic property. It can be molded in one time, with high dimensional accuracy and large degree of freedom, and the shape can be controlled by mold. It has good corrosion resistance, generally the surface coating is mostly epoxy resin, and after the coating treatment, it can adapt to various harsh environments. Bonded NdFeB is suitable for mass production, and it has low cost and high production efficiency. It has the advantages of high remanence, high coercivity, high magnetic energy product, easy to process various sizes and minimum specifications, etc. It is mainly used in the fields of office automation equipment, electric assembly machinery, audio-visual equipment, instruments and meters, small motors and measuring machinery, cell phones, etc.SourceRare earth magnet-https://www.rare-earthmagnet.com/process-of-bonded-ndfeb/

Bonded NdFeB ring picture.
Bonded NdFeB process is more strict. Bonded NdFeB is a kind of synthetic magnet, which is made of fast-hardened NdFeB magnetic powder and binder mixed through the process, and is directly molded into various shapes of permanent magnetic parts according to user requirements. There are four kinds of bonded NdFeB press molding process: calendering, injection molding, extrusion molding and molding, among which calendering and injection are more commonly used. Calendering is the process of mixing magnetic powder and binder in a certain volume ratio, rolling them into the required thickness and then curing them into finished products, usually using vinyl resin and nitrile rubber as bonding agent, and the surface of the product needs to be protected by plating. Injection molding is to mix magnetic powder and binder (thermoplastic resin), mix by heating, granulation, drying, then sent to heating chamber by screw guide rod, and inject into the mold cavity at a certain speed, after cooling, the finished product is obtained.SourceRare earth magnet-https://www.rare-earthmagnet.com/process-of-bonded-ndfeb/

Bonded Nd-Fe-B has the advantages of high dimensional accuracy, processing complex shapes, and uniform magnetic properties. This is the important reason why bonded NdFeB is widely used in various industries. As the manufacturing technology of bonded NdFeB permanent magnets continues to improve, especially the magnets produced by injection molding process and extrusion molding process, which can have complex or special shapes, are gradually gaining important applications in some new fields.SourceRare earth magnet-https://www.rare-earthmagnet.com/process-of-bonded-ndfeb/
