Introduction
Neodymium Magnets are widely used in many fields, such as motors, sensors,microphones, wind turbines, wind generators, VCMs in hard disk drives, printer,switchboard, loudspeakers, magnetic separation, magnetic hooks, magnetic holder,magnetic chuck, common daily use, and so on.
All kinds of micro permanent magnet ring is widely used in watches, optical communication, medical, precision machinery and other industries. Thin wall long hole features Micro NdFeB Ring is my company’s products, inner hole length to diameter ratio can reach those days, products can be thin wall thickness to 0.2 mm. Production, quality stable and reliable, and has been supporting in many world famous companies products.
