Our factories own advanced technology and machinery. We can produce various sizes of block-magnets, disc-magnets, ring-magnets, segment-magnets, cut-magnets, and other normal magnets. Furthermore, we are also able to manufacture the high-tech products ,Including isotropic radial rotor magnets, two-pole anisotropic cylindric magnets, magnetron magnets, anisotropic radial multi-pole ring magnets, super-large magnets, and high-precise super-thin magnets. These magnets are the most advanced level in China. It is usually be used in motors, speakers, electronic components, electric appliances, toys, stationery, and health articles. The products are of high quality and are exported to overseas markets.
