Abstract
A method of connecting parts relative to one another includes the steps of providing a first part, the first part having an opening; providing a second part, the second part having thermoplastic material in a solid state; arranging the first part and the second part relative to one another, so that the second part reaches into the opening, while a volume with an undercut is defined in the opening; causing a mechanical pressure and mechanical energy to act on the second part until at least a part of the thermoplastic material is caused to liquefy and to fill the volume; and causing the thermoplastic material to re-solidify, thereby anchoring the second part in the first part.
Claims18
A method of connecting parts relative to one another is provided, the method comprising the steps of
- providing a first part, the first part defining an opening and a cavity communicating with said opening;
- providing a second part, the second part comprising thermoplastic material in a solid state;
- arranging the first part and the second part relative to one another so that the second part reaches into the opening, and wherein said cavity has an undercut and a well-defined cavity volume, said cavity volume being delimited by cavity walls surrounding the cavity;
- causing energy to act on the second part until at least a part of the thermoplastic material is caused to liquefy and fill the cavity;
- and
- causing the thermoplastic material to re-solidify, thereby anchoring the second part in the first part, wherein the cavity walls delimiting the cavity volume are impermeable to the liquefied thermoplastic material.
