Product Description

NdFeB magnets .They are also called the neodymium magnets. Neodymium magnets are sintered magnets,they are have the fragile physical feature.Since rare earth magnets are have strong magnetic force,so they are very sensive to electrical signals and do offer accurate motions to the paper cone of the speaker,

Through these motional vol of the speaker will be clear and high.  Neodymium speaker / generator NdFeB magnet ringshaped  N40, strong and permanent magnetism ,awsome for speakers.

Main Manufacturing process of ndfeb magnets

1.Pressing ndfeb garins: pressing process was operated in strong magnetic environment.

2.Sintering of ndfeb blocks: sintering was processed in a vacuum furnace.

3.Wire cutting: ndfeb magnets are fragile materials operated in wire cut machines for the

tailored irregular shapes.

4.Grinding process: Grinding process: To reach the tolerance of magnets.

5.Plating: Neodymium magnets had been treated with different platings to prevent rust.

The popular platings for neodymium magnets are epoxy, nickel, NICUNI ,zinc and even

silver plating and gold plating.

6.Magnetization: the procedure are processed with magnetization machine with magnetic

feild ranged from 2~100 koe.
