Abstract

PURPOSE: To obtain a mechanically and magnetically superior magnet easily by a method wherein the magnetic grains to be mixed are disposed in surface treatment using a adhesive having good wetting property, and mixed with a binder to combine and shape.
CONSTITUTION: A raw material 8 to be filled up in a mold 1 is combined in a desired combining quantity. The magnetic grains are treated in surface coating with adhesive, and the rubber and the synthetic resin material, which are used as binder, are combined with the proper quantity of additive agent. The weighed and filled up raw material 8 in the mold 1 is bound and shaped by the pressure of punch 2 and extruded through the die 3. When it is pushed out of the mold 1, it is in the condition of improved magnetic characteristic by means of a pulsed magnetic field generated by the coil 4, and is shaped. By this way, the border face between the grain and rubber is strongly joined by the adhesive without a fear of cracking or separation, and the magnetic characteristic is stabilized.
