Abstract (en)
[origin: WO0029631A1] The invention relates to a method for producing soft-magnetic sintered components, according to which first the shape of a green body is produced by pressing and said green body is then sintered. As starting materials (A, B, C) for pressing the green body a mixture (1) of a powder mix, which contains at least between 5 and 30 % by weight, in relation to the total starting materials, of fine powder and has a mean particle size of between 5 and 40 mu m, and a thermoplastic binder is used. This mixture is pressed (2) into the green body at a temperature higher than the softening temperature of the binder, after which the green body obtained in this way is sintered (3).
