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.
I. Injection Bonded Ferrite Magnet Properties It is a new kind of composite permanent magnetic material with the features of flexible shaping, precision dimension, adjustable magnetic properties, fine coherence, composite molding, elastic magnetization and high mechanical strength.
Low cost, widely used in many different applications ,stable magnetic property with strong demagnetization resistance capability. Good corrosion resistance capability, no coating. The injection bonded ferrite magnet is widely applied in core components and parts of micro machine, location sensor, buzzer, contactless distributor For automotive and home appliance industry.
Features and benefits of injection molded ferrite
Injection molded magnets can be of very complex shapes with high precision, typically, tolerance is+/-
0.005mm, it is suitable for high precision parts
It is a new technology to achieve adjustable magnetic properties, composite molding, elastic magnetization
and high mechanical strength
By doing insert molding, magnetic material can be directly molded into or onto other assembly
components without further assembly process
The material is harder to be cracked or chipped than sintered magnet
