Injection magnet is a mixture of magnetic powder, resin, additive, which are injective produced by a specialized injection machine. The injection magnet power is lower than sintered magnet, but it has precise sizes, light-weighted, compact and various shapes.
Rare earth magnet
It is made of ndfeb magnetic powder and the plastic materials. Isotropic magnet which fits for complex sizes and multi-pole magnetize. It must be protected under the electroplating, the precision are high, but easy to broken and can not process to special shape.
Sintered Ferrite Magnet
Mainly made from Fe2O3, BaCo3 or SrCo3 metallic powders. There are two types : One is isotropic magnet and the other is anisotropic magnet.(anisotropic magnet included the dry compression and wet compression). The property included the corruptive is very high, not easy to demagnetize. The normal tolerance is +/-2%, after process, the tolerance can be +/-0.05%.
Rubber magnet
Anisotropic and isotropic rubber magnets are composite materials made of permanent magnetic powder with high polymer material by means of calendaring or extrusion. They show good magnetic properties and high sizing precision.
Injection ndfeb magnet
It is a mixture of resin (pa12, pps) & the ndfeb magnetic powder, after mix together with the additive, injective produced the magnet is called injection ndfeb magnet.
