Abstract
본 발명은 링상 수지자석의 제조방법에 관한 것으로, 자석분말과 수지를 혼합한 분말을 프레스로 가압하여 성형하는 성형공정(S1)과, 상기 성형공정(S1)에서 생산된 성형체에 강도를 부여하기 위해 가열된 오븐에서 수지를 용융시시켜 자석분말을 가교시켜주는 경화공정(S3)으로 이루어진 링상 수지자석의 제조방법에 있어서, 상기 성형공정(S1)에 의해 성형된 링상의 성형체(10)의 내주면(14)에 소정의 치수로 가공된 수지자석보다 강성의 봉(12)을 끼워맞춤으로 삽입시킨 후, 상기의 봉(12)과 링상 성형체(17)를 오븐에서 함께 가열하여 경화시키므로써 링상 수지자석의 치수편차를 최소화시키게 된 것이다.The present invention relates to a method for producing a ring-shaped resin magnet, the molding step (S1) for pressing and molding the powder mixed with the magnet powder and the resin and to give strength to the molded product produced in the molding step (S1) In the method for producing a ring-shaped resin magnet consisting of a curing step (S3) for melting the resin in the heated oven to crosslink the magnet powder, the inner peripheral surface of the ring-shaped molded body 10 formed by the molding step (S1) After inserting the rod 12 that is rigider than the resin magnet processed to a predetermined dimension into the fitting 14 by fitting, the rod 12 and the ring-shaped molded body 17 are heated together in an oven and cured to form a ring-shaped resin. The dimensional deviation of the magnet is minimized.
