Abstract

PURPOSE: To be able to form a rubber magnet in the condition that the direction of easy magnetization are fully put in order by a method wherein a pulsed magnetic field is applied to a mixture when it is combined and shaped by press.
CONSTITUTION: A raw material 8, which is composed of rubber, synthetic resin binder and magnet or magnetic powder compounded in a desired compounding ratio, is filled up in a mold 1. The raw material 8 is combined and shaped in the mold 1 according to the applied pressure by a punch 2 and a die 3. In this time, the mixed magnetic powders are put in order in the direction of easy magnetization by the pulsed magnetic field generated by a coil 4, and are shaped in the improved magnetic characteristic condition. As the pulsed magnetic field can affect an impacting greater magnetizing force than a statical magnetic field, the magnetic powders in the shaping process are easily put in order in the direction of easy magnetization and are shaped in the condition of fully arranged in the direction of easy magnetization. Therefore a magnet of distinguished magnetic characteristic can easily be obtained.
