Customized Nickel Coated Magnet Permanent Magnet

There are sintered Neodymium Magnet and bonded neodymium magnet, sintered type retains much strongger magnetism, bonded type is available for complex customized shapes. we mainly produce the sintered type with regular shapes like arc, round disc, rectangular, cylinder,ring,trapezoid.

Neodymium magnets, or ndfeb magnets are magnetic alloys which consist of neodymium,iron and boron. Neodymium magnet has prodigious magnetic power.the working temperature of N grade was 80℃. If high working temperature is required,higher grade of neodymium magnet will be needed.

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.
