Bonded Mould Compression NdFeB Magnet

Compression bonded magnets are composed of a special form of NdFeB powder with adhesive and using compression molding techniques in simple tools, it can be quickly machined into complex shapes. Since its materials are isotropic, bonded NdFeB magnet can be magnetized in any direction or with multiple poles. Special magnetizing fixtures are required in order to achieve multiple poles magnetization, depending on complexity of design and production.
