Abstract

본 발명은 간단한 구조의 열간압축 금형 및 다이업셋 금형을 사용하여 이방성 수지 자석 분말을 제조한 후 사출 및 압축 성형으로 영구자석을 제조할 수 있는 이방성 수지 영구자석 제조방법을 제공하는 데 있고, 자성분말을 튜브형 부재내에 넣는 단계와, 400 내지 1000℃의 온도에서 가압 부재를 작용시켜 상기 튜브형 부재와 함께 자성분말을 열간압축하여 고밀도의 등방성 성형체를 얻는 단계와, 상기 성형체가 자기 이방성을 갖도로 400 내지 1000℃의 온도에서 가압부재를 작용시켜 상기 튜브형 부재와 함께 성형체를 열간가공하는 단계와, 상기 이방화된 성형체를 튜브형 부재와 분리한 후 분쇄하여 이방성 파우더를 만드는 단계와, 상기 이방성 파우더에 수지를 믹싱한 후 자장중에서 사출 및 압축 성형하는 단계로 제조되는 것이다.
