Abstract
A method of bonding a second object to a first object includes: providing the first object, which includes a thermoplastic liquefiable material in a solid state; providing the second object, which includes a surface portion that has a coupling structure with an undercut such that the second object can make a positive-fit connection with the first object; and pressing the second object against the first object with a tool that is in physical contact with a coupling-in structure of the second object while mechanical vibrations are coupled into the tool. The step of pressing and coupling vibrations into the tool continues until a flow portion of the thermoplastic material of the first object is liquefied and flows into the coupling structures of the second object. Thereafter, the thermoplastic material of the first object is permitted to re-solidify to yield a positive-fit connection between the first and second objects.
