Products
We manufacture to drawing and magnetic specification — selecting the grade, coating and magnetization pattern for your operating temperature and demagnetization environment.
Curved magnets for surface-mount and built-in rotor designs in BLDC, servo, PMSM and traction motors.
Standard and custom geometries ground to tight flatness and parallelism for fixtures, sensors and couplings.
Magnets bonded and retained into housings, rotors and shafts — delivered as a ready-to-install component.
Magnet plates and tracks arranged in optimized pole patterns for linear motors and direct-drive axes.
Irregular, miniaturized and wire-cut profiles for consumer electronics, encoders and precision devices.
Protective finishes selected for your corrosion and assembly environment, applied in-house and tested.
Sintered NdFeB is the third-generation permanent magnet made from the rare-earth metal neodymium, iron and boron by powder metallurgy — the strongest magnetic material in the world today. It is produced through both traditional sintering (high-temperature sintering and grain-boundary diffusion, mainly for high-energy-product and high-coercivity products) and the hot-extrusion route (mainly for radial rings). With a complete processing system for cutting, surface treatment and inspection packaging, the minimum machinable size reaches 0.2 mm, and magnetization can be programmed to customer requirements. Products are widely used in automotive, clean energy, medical devices, aerospace and other fields.
