Magnetic compound material is mixed by ferrite magnetic powder and plastic resin in mixer, through mixing ,smelting, cooling, shaping and cutting process to produce final magnetic compound. Unimagnet uses imported automatic production line to manufacture magnetic compound which has high performance, good flexibility and stable granularity.
According to different producing technics, there are two kinds of magnetic compounds: injection magnetic compound and extrusion magnetic compound.
Injection magnetic compound is mainly used for producing permanent DC motor, stepper motor, printer and Magrollers of photocopier, bounce cylinder, inductor and Teletron gathering piece. Extrusion magnetic compound is mainly used for producing refrigerator door gaskets and other door seal gaskets.
