Process for joining a metallic bolt to a plastic workpiece

摘要

A metallic stud or bolt (1) is attached to a plastic component (2) by rotating it (3) and pressing (4) it into the plastic at the same time. The plastic melts due to friction and the stud is anchored by interlocking deformation. The surface of the stud can have surface serration and the tip (5) of the stud can deform to a larger diameter (D). The stud can be used to join two plastic components or to attach metal parts to plastic. The stud can have a head to be friction-welded to a metal part at the same time.
