Abstract: Method of cold forming a blank made of press sintered material which includes moving at least one tool towards the blank and subjecting the blank to rolling under a roughly constant load for a number of passes until the at least one tool reaches a chosen position. At least one of, the chosen position, the roughly constant load, and the corresponding number of passes, is determined so as to control a surface densification and at least one dimension of the rolled blank.

Abstract: Method of cold forming by rolling of a blank made of press sintered material, in which at least one tool of predetermined peripheral geometry is brought close to the blank, so that the tool can then be rolled over the blank, urging the one towards the other, characterized in that it comprises, after a phase (a) of approaching the blank, a penetration phase (b), with (bn) at least one phase of rolling under roughly constant load, as far as a chosen position, this load, the chosen position, and the corresponding number of passes being determined so as to control the surface densification and the dimensions of the rolled part.
