Abstract

PURPOSE: To mix magnet particles with a binder uniformly and provide a rubber magnet of maximum high energy product by a method wherein a rubbery binder is used in the form of powder and magnet particles are mixed with the powder.
CONSTITUTION: A rubbery binder powder (made of rubber or synthetic resin) added with such additives as vulcanizing agent, vulcanization accelerator, pigments, and the like is fed from a hopper 2 into a mixer 3, where it is mixed with magnetic particles fed from a hopper 1. The mixed powder in the mixer 3 is fed to an extruder main body 6, filled in the main body 6 in a metered amount, and extruded through a die 8 by the compression force of a punch 7, to produce a bound and formed body. Because the mixed magnetic powder is well aligned in spin direction and improved in magnetic characteristics by the pulse field generated by a coil 9 before extruded, so that the rubber magnet obtained has largely improved magnetic characteristics. The formed body extruded through the die 8 is then vulcanized under heating by a coil 11, to obtain a formed body bound rigidly and integrally.
