Sintered Nd-Fe-B magnets

Our Rare-earth Nd-Fe-B magnet can be categorized into certain two types which are sintered Nd-Fe-B magnets and bonded Nd-Fe-B magnets. They are widely used in mobile phones, tablets, speakers, vibrating motors, voice coil motors, liner motors, manual sockets, computer accessories, etc., especially in magnetic assemblies (adding shunt, aluminium products, diaphragm, PSA, and AB glue).

We also have expertise in mass production automatically and manufacture our products in clean workplaces, in order to achieve best quality results.
