Isotropic Ferrite Multipole Magnet Rings

 

Isotropic sintered ferrite magnets’ magnetic properties are low, they have nearly the same magnetic properties in all directions,can be magnetized in many different directions in multi-poles; 

 

Dry Press radial multipole ferrite magnetic ring includes molding, sintering, grinding machining, injection molding and magnetizing processes. The Products are with excellent performance, especially for the dry pressing anisotropic magnetic ring witch the highest magnetic density is up to 1600-1700GS. According to customer’s requirements to design and development as well provide all kinds of injection molding magnets. The products are widely used in synchronous motor. Micro motor, pump motor, toy motors, sensors, electronic instruments and other fields.

 

 

II:Manufacturing process and magnetizing

 

 With dry process can produce isotropic & anisotropic magnets, the tool can be changed and developed easily.

 With wet process only can produce anisotropic magnets,it is complicated to  change the tool and the tooling charge is high.

 Isotropic ferrite magnets can be magnetized in any direction.

 Anisotropic ferrite magnets are all oriented in the manufacturing direction, and can be magnetized in the direction of orientation.
