Product Description
General Description
1, Injection molded ndfeb magnets can be of very simple shapes or very complex
2, All or only part of the device may be magnetized
3, It is sometimes cost advantageous to make an entire part out of the magnet material and just magnetize the portion requiring magnetic output
4, Bonded magnets can be made from either hard ferrite materials or rare earth magnetic powder
