Injection  Molded  NdFeB  MagnetGeneral 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
    5, They are manufactured using both injection molding and compression bonding techniques which are fully automated and are particularly suitable for high volume production
    6, We are original Injection Moulded NdFeB magnet manufacturer in China, our magnets are made with the highest quality..
