Integrated manufacturing

From magnetic powder to finished rotor.

Every stage happens under one roof in Mianyang — giving engineering teams a single point of control over material, magnet and assembly.

  1. 01

    Magnetic powder

    Melt-spun bonded NdFeB powder, produced in-house by a team focused on powder since 2009.

  2. 02

    Bonded magnets

    Powder and binder are mixed, compression molded, cured, surface treated and magnetized.

  3. 03

    Rotor assemblies

    Finished magnets are injection molded into gear-shaft rotor assemblies, then fully inspected.
