also called plastic magnets , are made of bonded ferrite magnet powder, Plastics ( pvc, nylon, pp, etc) and other materials, By injecting process, the combination can be made into flexible magnets with precise sizes and complicated shapes. It can be inserted in metal and plastic pieces.
The precision tooling is necessary to ensure the products dimensional tolerance. The magnets dimension would be change after cooling due to the thermoplastics shrinkage.
They are widely used in DC permanent motor, step motor, meter motor, position sensor , printer and duplicator roller, cushion cylinder, inductor, and kinescope collector, etc.
