Method of manufacturing a part having a mechanically weakened area forming a hole or a hole precursor, and section obtained in this way |
摘要 |
A method for making a part with at least a mechanically weakened zone, including a step of producing a thermoplastic part (10), and at least a cycle of steps which include: locally producing a through recess in a zone of the part having a constant thickness; locally heating the part using a heat probe (15) so as to make the zone of the part plastic; modifying with a punch (15) the geometry of the resulting plastic zone so as to define in the part a mechanically weakened zone constituting a hole or a hole outline.
