Abstract
The invention concerns a method for joining a metal component and a polymer component, and a structure comprising said components. In the method, an extrusion die plate with a through hole is placed between the metal component and the polymer component. A probe is rotated and plunged across the thickness of the metal component and eventually through said through hole of the extrusion die plate, thereby extruding a part of the metal component through said through hole of the extrusion die plate into the polymer component. The probe has a rotation axis having an offset to the centre of the through hole during the rotating and plunging action.

A method for joining a metal component and a polymer component, the method comprising:
- obtaining a metal component and a polymer component;
- obtaining an extrusion die plate having one through hole;
- placing the extrusion die plate between said metal component and said polymer component;
- rotating and plunging a probe of a non-consumable and rigid tool across the thickness of the metal component and eventually through said through hole of the extrusion die plate, thereby extruding a part of the metal component through said through hole of the extrusion die plate into the polymer component,
- wherein the probe has a rotation axis having an offset to the centre of said through hole of the extrusion die plate during the rotating and plunging action.
A structure comprising a metal component and a polymer component having a spot welding or dissimilar overlap joint between said metal component and said polymer component, wherein the structure comprises an extrusion die plate disposed between overlapping metal component and polymer component, which extrusion die plate has one or more through holes, wherein the structure comprises a non-axis-symmetrical hook made of the metal component and extruded into the polymer component through said one or more through holes.
