Product Description

Neodymium magnets retains strong magnetic power in the small sizes and mass. As of today, the neodymium magnets are applied in consume electronic products like smart phones,computers. etc. The neodymium magnets also been used in the generators,speakers, telephones,computers,cars, DC motors, odometers and sensors...

Generally, neodymium magnet are refer to neodymium iron boron magnets, or ndfeb magnets in short. Neodymium magnets  rare earth magnets,they are cosist of lanthanide elements neodymium with ferromagnetic materials.

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 processGrinding 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.
