Embodiment Construction
[0058] FIG. 1 shows an automotive part, generally designated 10 , comprising a metal plate 12 for forming a metal body and comprising a peripheral region 14 covered with a plastic body 16 . The outer border 18 of the metal plate 12 defines a first frontier of the peripheral area 14 , the inner border of the peripheral area 14 is indicated by 20 , ie the limit of the metal plate 12 covered by the plastic 16 . Metal plate 12 includes two opposing planes 40 and 42 that meet at outer boundary 18 .
[0059] The plastic body 16 includes a plurality of studs 22 integrally formed therewith for positioning automotive parts. Other functional elements can also be integrally formed with the plastic body 16 . In the example shown, the car part is the roof. However, the part could also be an underbody panel.
[0060] FIG. 2 shows a mold 24 according to the invention for making part 10 of FIG. 1 . The mold 24 comprises two half-moulds 26 and 28 capable of relative translation in a vertic...

Abstract
The invention relates to a mold (24) for manufacturing an automobile part (10), including a metal body (12), at least one peripheral area (14) of which is covered in a body made of plastic material, including: at least one molding cavity (30) of the plastic material body (16), defined by walls (32, 34) defining the general shape of the plastic material body (16); abutments (36, 37), projecting from the walls (32, 34), for positioning the metal body (12) at least partially remote from the walls (32, 34) of the mold (24), the abutments (36, 37) being equipped such that, when the mold (24) is in a closed position, they constrain the peripheral area (14) into a shape that, once the part (10) is manufactured, prevents the dislodging of the metal body (12) from the plastic material body by translation or rotation.
