Common surface treatment procedures for NdFeB magnetic rings

NdFeB magnetic rings are now not only used in some mechanical equipment, but also in many toys and packaging boxes. Many manufacturers will use them when they produce them. The magnetic rings made of NdFeB have strong magnetic force and moderate price. Many people don't know much about the surface treatment of NdFeB production, so let's share it below!

The common surface treatment procedures of NdFeB magnetic rings are mainly as follows:

1. Nano (Royce3010) chelating film without coating treatment; 3010 means that the film layer contains more than 3 active chelating groups, and the thickness of the film layer is 10 nanometers;

2. Phosphating;

3. Electroplating;

4. Electrophoresis;

5. Vacuum vapor deposition;

6. Electroless plating;

7. Organic plastic spraying.

The above is the common surface treatment process of NdFeB magnetic ring!
