The end is then swaged to form an expanded region (') and a preformed tubular insert () of a thermoplastic material is inserted to cover the holes () on the inside. An outer part () of the same thermoplastic material is then overmolded on the outside of the shaftso that its material () flows through the holes () and bonds with the inner insert (), thereby securing the inner and outer parts together around the end of the shaft.
