ABSTRACT:
The process is remarkable in that after the slug of the part to be obtained has been made, one or more inserts are provided which can be centered and introduced into the opening or openings, (1.1) and/or the recess or recesses, and/or the blind hole or holes (1.2) formed ahead of time on the slug, these inserts being prepositioned on a working die (3), and by the fact that this is followed by a stamping operation using a punch (5) or similar device permitting the final shaping of the part to be obtained and deformation of the material to permit the fixed and permanent integration by crimping of the insert or inserts (2), so as to create local reinforcement zones in terms of the needs and applications and uses of the part thus obtained.
