According to the method, an elongate element (20) is formed from a composite material and a coil is formed by winding the elongate element (20) around a master model (24). The master model (24) provides the coil with the general shape of a continuous ring and with dimensions that allow the resulting coil to form an insert (2) equipped with at least two parts that are intended to extend through at least two separate opening panel zones to be reinforced.

The invention relates to a mould (1) for manufacturing a plastic part (MP), comprising a first element (3) and a second element (4) forming, in the closed position of the mould (1), a cavity (5) corresponding to the part (2) to be manufactured, in which the second element (4) comprises at least one system (6) for making moulding openings in said part (2), said system (6) comprising at least one member (7) forming a cavity of an opening for the finished part (2), said member (7) being movable relative to the second element (4) in the closing direction of the mould (1), between a retracted position and an position extending into the cavity (5). The system (6) comprises at least one positioning means (8) for positioning the member (7) in the extended position relative to the first element (3), said system (6) being sized such that, in the extended position of the member (7), the distance between a surface of the member (7) bearing on the plastic material (MP) and the first element (3) enables the formation of a thin layer of plastic material having a repeatable thickness.

An assembly is provided. The assembly comprises a towing hook orifice covering plate (10) and a skin (20), wherein the towing hook orifice covering plate comprises a covering plate modeling surface (10a) facing the outside of a bumper and a covering plate structural surface (10b) facing the inside of the bumper. The covering plate structural surface has oppositely arranged rotary lugs (13a, 13b) that are perpendicular to the covering plate structural surface and extend therefrom, and the rotary lugs have arc surfaces (131a, 131b) away from the covering plate structural surface. The skin (2) has grooves (21a, 21 b) for accommodating the rotary lugs, and the grooves comprise first arc sections (211a, 211b), linear sections (212a, 212b) and second arc sections (213a, 213b), wherein the linear sections are located between the first arc sections and the second arc sections. The assembly has a rotating axis defined by the rotary lugs and solves the interference problem in the prior art by changing the position of the rotating axis. The assembly maintains the vehicle outlook by not changing the appearance of the covering plate modeling surface, and can satisfy the requirements for the opening of the towing hook orifice covering plate and for the gap between the towing hook orifice covering plate and the skin.
