The compaction molding attached ultrasonic vibration, which was applied longtitudinaly through upper punch was studied for the bonded magnet composed of an anisotropic Nd-Fe-B powder and an epoxy resin binder in order to melt binder without heating of mold. In this work, the influence of the amplitude and duration of ultrasonic vibration on the compound temperature in the dies was investigated. The results show that the minimum time of ultrasonic vibration required for binder melting can be shortened by increasing the amplitude, then bonded magnets can be compacted efficiently. The bonded magnets made by this method have a powder volume fraction of 77.7% at compacting pressure of 550MPa. This value of compacting pressure is lower than that of warm compaction molding required to obtain same volume fraction.
