Multi Poles Anisotropic Bonded Neodymium Magnets With Epoxy Coating

Customized Multi Poles Anisotropic Bonded Neodymium Magnets With Epoxy Coating

Customized Multi Poles Injection Molded Anisotropic Bonded Neodymium Magnets

Bonded Neodymium magnets are made of the powerful Nd-Fe-B material mixed into an epoxy binder. The mix is approximately 97 vol% magnet material to 3 vol% epoxy. The manufacturing process involves combining Nd-Fe-B powder with an epoxy binder and compressing the mixture in a press and curing the part in an oven.

Advantages Of Compression Bonded Magnets

1: Higher magnetic strength than injection molded magnet.

2: High corrosion resistance (Epoxy coating, parylene coating) and temperature resistance, the salt spray teasting >72 hours

3: Magnetizing with complex patterns (Multi-poles on OD, ID, end face (axial), radial, helical magnetization......)

4: Higher magnetic property (Br: 3500-8000G, BHmax: 3-12MGOe, Hcj: 4000-17000 Oe

5: Complicated shape
