Method of manufacturing a part having a mechanically weakened area forming a hole or a hole precursor |
摘要 |
A method of manufacturing a part having at least one mechanically weakened area includes a step of producing a thermoplastics material part and at least one cycle of steps entailing forming a localized opening through an area of the part, heating the part locally by means of a heating probe so as to render the aforementioned area of the part plastic, and using a punch to modify the geometry of the area rendered plastic so as to delimit in the part a mechanically weakened area constituting a hole or hole precursor.
