Product Description

Rare earth magnets include neodymium magnets and samarium cobalt magnets.They producing significantly stronger magnetic fields than ferrite and alnico magnet. Rare earth magnets are extensively applied in modern industry, we can find rare earth magnet in our surrandings.Neodymium magnets are extensively employed in the modern industry applications. Rare earth magnet are brittle magnetic materials,they might chipping when steels impact on it.

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.
