1. A laminated core (10) for a stator or rotor of an electric machine, the laminated core (10) comprising: multiple laminations (12) stacked one on top of another in an axial direction (14) to form a lamination stack (16) having opposite first and second axial end faces, through-openings (18) extending through the laminations (12) in the lamination stack (16) from the first axial end face to the second axial end face and aligned parallel to the axial direction (14); tie rods (20) of plastic injection molded respectively in the through-openings (18) to assemble the laminated core (10), opposite axial end portions (30) of the tie rods (20) being cross-sectionally widened with respect to the respective through-opening (18) and extending respectively onto the first and second axial end faces; a plastic outer sheath (34) injection molded around an outer circumferential side (23) of the lamination stack (16) and encapsulating the outer circumferential side (23) of the lamination stack (16) continuously from the first axial end face to the second axial end face; and first and second end disks (36) that respectively cover the opposite first and second axial end faces of the lamination stack (16) at least in certain portions, the first and second end disks (36) being connected to the outer sheath (34).
