摘要： The present invention relates to a method in which a magnetic powder is packed into a cavity (c) of a rubber mold (m) comprising a rubber material at least a part of which is a mixture of rubber and magnetic powder, and then the rubber mold filled with the magnetic powder are subjected to a magnetic field and a pressure with punches (2a , 2b), thereby compressing the powder to form powder compact. This makes the distribution of magnetic field in the cavity of the rubber mold more homogeneous, and therefore, the distortion, cracking and chipping caused by inhomogenity of the distribution of the magnetic field are prevented, and the resultant powder compact becomes more near-net-shaped i.e., closer to the end product.

摘要： In the die-pressing method of the magnet powder and fine powder, the powder is filled at a high density in a rubber mold (10), is occasionally preliminarily magnetized (4a) in the rubber mold and is then compacted under magnetic field or without magnetic field. Cracking of the magnet green compact is prevented. A sintered compact having density of 90% or more can be produced using the fine powder.
