Rare Earth Magnets Bonded Magnet

I need a complex magnet shape or a tight tolerance without grinding. Who moulds bonded magnets?

What it is

Magnet powder held in a polymer binder and injection or compression moulded to shape. Lower energy product than a sintered magnet, but it can be moulded to complex net shape, holds tight tolerance without grinding, and does not corrode the way bare sintered NdFeB does.

Typical dimensions
Net shape moulded; complex geometry and thin walls are practical.
Also known as
polymer bonded magnet, injection moulded magnet, compression bonded magnet
