Which performance is better when NdFeB magnets are processed and molded?

Generally, the magnetic properties of sintered NdFeB, such as Br, HCI and BHMAX, are higher than those of bonded NdFeB magnets. However, due to its processing characteristics, it is difficult to manufacture magnets with small size and complex shape.

The main advantage of bonded NdFeB magnet is that it has higher magnetic properties than ferrite, and it can manufacture magnets with smaller size and complex shape.

The difference between compression molding and injection molding lies in the different types of adhesives. Generally, compression molding uses thermosetting resin such as epoxy resin, while injection molding uses thermoplastic resin such as nylon.

There are many manufacturers of sintered boron magnets, so the code name is not clear.

Bonded NdFeB is produced by magnetic powder produced by McKin Magnetic Company, and the patent is monopolized.

If we only talk about magnetism, of course, sintering is the strongest.
