The complete combination of injecting process and high-property rare-earth powder makes it possible to form easily the anisotropic(especially radial anisotrotropic)super-thin ring or block magnets in complex shapes.The products can be formed in a unit together with other components.This process provides high precision and high acceptable rate of products.
Usages:
1. The compression molding magnets, as for simple mould and high magnetic properties, are widely used in stepping motor, CD-ROM spindle motor, general motor, vibrating motor, pick-up, HDD spindle motor, and FDD spindle motor.
2. The injection molding magnets, as for complex mould, magnetic properties around 6 to 7 MGOe, and highly consistency, are widely used in electric expansion valve, air-condition motor etc,.
