Bonded NdFeB Magnets and Assemblies Bonded NdFeb is a kind of magnetic material which contains binder and takes NdFeB alloy as main component.Bonded Neodymium-Iron boron generally includes two types: molding (thermo-hardening resin binder) and injection molding (thermo-plastic resin binder).The company has been engaged in the production and manufacturing of rare earth permanent magnets since 1989, [...]
Compression Bonded Moulded NdFeB Magnet Compression bonded magnets are composed of a special form of NdFeB powder with adhesive and using compression molding techniques in simple tools, it can be quickly machined into complex shapes. Since its materials are isotropic, bonded NdFeB magnet can be magnetized in any direction or with multiple poles. Special magnetizing [...]
Method of moulding radial ring magnet and device thereof Method and apparatus for forming radiation-oriented annular magnets The present invention relates to a method and apparatus for making a radiation-oriented annular magnetic material, and more particularly to a method and apparatus for forming an annular magnet that is radially oriented in a radius or diameter [...]

Plastic Bonded Pressed Magnets / Plastic Bonded Magnets Plastic bonded pressed magnets are the result of the union between thermoplastic binders and permanent magnet powders, and can be made in isotropic or anisotropic qualities. Pressed magnets are magnetic products manufactured with high precision and tailored for each application. Type of material Magnetic powders: ferrite or [...]
Radial multipole rotor magnet Radial multi-pole magnetic rotor is a magnet product of MPCO magnet manufacturers, and it is one of the products we are proud of. This is not only because our motor rotor magnets continue to sell well, but also because of us. The magnetic steel is really helping the user. The company [...]
AXIAL MAGNETIC RINGS for SENSOR Magnetic rings for use in harsh environments The robust magnetic rings consist of a vulcanised elastoferrite layer securely attached to a steel hub. The elastoferrite layer is magnetised with 2 mm or 5 mm long alternating magnetic poles which form an incremental magnetic pattern. Additionally, reference mark magnetic signature can [...]
Isotropic polymer bonded NdFeB magnets - The raw material powder is manufactured by rapid quenching of prescribed alloys into nanocristalline flakes which are subsequently annealed for optimum magnetic properties. Shortly after the invention of rapidly quenched NdFeB magnet powders, MPCO had started to develop polymer bonded magnets from these powders. Isotropic polymer bonded NdFeB [...]
Typical Compression Bonded Magnetic Properties Many suppliers publish specifications for a nominal 10 MGOe magnets with a minimum limit of 9 MGOe. Similar for a nominal 11 MGOe magnet; minimum limit is 10 MGOe. Have to design to lower limit of BHmax Typical Compression Bonded Magnetic Properties BHmax Improvement in Compression Bonded Magnets The BHmax of a compression bonded isotropic NdFeB magnet is influenced by the following two factors: 1. Volume fraction of magnetic phase in the magnet – typically measured by the density of the magnet. • We are investigating increasing the pressing pressure which requires special press construction, lubricants and tooling materials – current production pressing pressures are 7tonnes/cm2 for 5.9 g/cm3 and 10MGOe; estimated that > 20 tonnes/cm2 required for 6.3 g/cm3 and > 11 MGOe. • Optimize the particle encapsulation chemistry and process. • Tailored multimodal PSD’s for maximum packing density. • Particle shape control. 2. Magnetic powder Br/BHmax • Increase isotropic Br of powders while maintaining sufficient Hci to have “linear” B‐H demagnetization characteristic at the application temperature.
