Bonded Ferrite is either injection or compression molded, and typically uses Nylon 6 or Nylon 12 when injection molded. Compression molded (which is very rare) is made by using epoxy mixed into the
ferrite. Typically most bonded ferrite uses strontium ferrite. It costs slightly more than sintered ferrite because ferrite must be powderized and mixed with the appropriate material for carrying of the ferrite.
The ferrite can be aligned in the mold which saves a secondary step. Note: bonded ferrite can also be calendared in sheets, rolls, & strips. Calendared material either uses CPEinfo-icon or Butyl Nitride.  injection molded ferrite magnets, ferrite insert molded magnets, anisotropic bonded ferrite magnets
Typical applications: sensors and encoders.

Injection Molded:  Injection molded ferrite magnets
Injection molded Ferrite is another molding process of magnet category. Compared to injection molded NdFeB, the difference of injection molded Ferrite lies in different magnetic powder utilized,
therefore injection molded ferrite has lower magnetic properties due to ferrite features, but it costs much less than that of NdFeB.
Binder Types / Nylon / PPS / Polyamide.
Temperature Range -40c – 180c
Very Tight tolerances off tool ( 0.002 -0.003 Typical )
Very good mechanical strength

Injection bonded ferrite magnets offer a combination of high magnetic strength and excellent physical properties. They offer large scale manufacture of shaped parts of close dimensional and magnetic
tolerances, and therefore resulting in finished products of which usually need no further finishing machining. This deprives subsequent operations of the magnet and therefore reduces the total cost.
