Product Description

Rare earth magnets was commonly unfamiliar to the general public. They were more extensively to know strong magnet instead of rare earth magnet. Rare earth magnets is the very important material in electric and electronic domain.The strong magnetic power of rare earth magnet can generate electricity and motive power,rare earth magnets also could identify magnetic signals.

There are two sort of rare earth magnets, neodymium magnets and smco magnets. Neodymium magnets retain the magnetism much strongger than smco magnets. Neodymium magnets, either insect individual magnet or inserted into assembly, are extensively applied in modern industry due to their enormous magnetic properties and reasonable price.

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.
