METHOD FOR MANUFACTURING GREEN COMPACT FOR SINTERED MAGNET AND APPARATUS THEREFOR

PROBLEM TO BE SOLVED : To manufacture a green compact superior in orientability for a sintered magnet, by reducing friction occurring among magnetic powders when being pressed in a magnetic field.SOLUTION : The method for manufacturing the green compact for the sintered magnet containing a rare earth element comprises sticking ultrasonic vibrators 1 and 2 onto the die body 11 of a press die 10, and pressing the magnetic powder M in a magnetic field while ultrasonically vibrating the powder filled in the press die 10.
