Enabling “free rotor design”
The World’s strongest bonded magnets

MAGFINE is the world’s strongest anisotropic bonded magnet.

Its high freedom of form helps in achieving application performance equivalent to or better than that of neodymium-based sintered magnets in motor actuator manufacturing.
In addition to omission of manufacturing process through integrated injection molding, bonded magnets also have features such as being free of heavy rare earth metals.

With MAGFINE, we are committed to working together with our customers to create the ultimate product.

Strengths ofMAGFINE

  • MaterialsThe world’s strongest bonded magnet

    MAGFINE uses anisotropic magnetic powder that has outstanding magnetic properties. It has the world’s strongest magnetic force as an anisotropic Nd-Fe-B bonded magnet. As it is a composite material consisting of magnetic powder and resin, it has immense flexibility and boasts high compatibility with ideal motor designs.

  • Manufacturing processOmission of manufacturing process

    MAGFINE can be molded into various forms, and actualizes integrated injection molding by direct mixing during rotor core manufacturing. As a result, processes of cutting machining, assembly bonding, and magnetization which were previously necessary are omitted contributing to reductions in personnel and equipment.

    Manufacturing process
  • Resource savingHeavy rare earth metals

    We do not use the rare earth elements Dy and Tb that are subject to significant supply and price fluctuations, and for which environmental pollution during mining is an issue. We also do not use Co, a specific chemical substance that can lead to health issues. In addition to considering environment and health concerns, we have also reduced risks in procuring of resources.
