    One of the more important developments in magnetic materials is polymer bonded magnets. This has opened a new world of application opportunities. The processing temperatures employed to blend and mold the material mixture is low enough to allow many different magnet powders to be used alone or in combination in the polymer binder to achieve an unprecedented range of properties.

    Tolerances
    An important characteristic of injection molded magnets is that they conform dimensionally to the precisely-machined mold cavity, the result being close tolerances in the finished product. What little
    dimensional variability there is results from shrinkage of the polymer during cooling. This depends upon part thickness and shape. Typical tolerances are +/-0.003 in/in. Closer tolerances on critical
    dimensions can be negotiated. ferrite injection plastic magnets

    Temperature Characteristics
    Maximum use temperature is a function of both the magnetic alloy powder and of the binder. For example, ferrite powders in nylon 6 or PPS have tested satisfactorily at 150°C and 180°C respectively. On the other hand, nylon 12 melts above 170°C and is not recommended for use above 150°C. Magnetic material such as the highest energy NdFeB grade, with intrinsic coercivity of 9,500 Oersteds (760 kA/m),  suffers significant irreversible magnetic loss above 120°C, regardless of which binder is used. Maximum use temperatures are listed on each product’s specification sheet. injection ferrite rotor magnets
