The present invention relates to a manufacturing process for a composite part comprising at least two different appearances and/or feels in the region of at least two apparent surface zones, said part consisting of a thermoplastic skin and a material covering the internal side of the skin. Process characterised in that it basically consists of providing a skin (3) with said at least two different appearances and/or feels in the region of the surface zones (2, 2', 2'') concerned, a localised deformation in the form of a groove or recess (5) of said skin (3) being present at each interface between two surface zones (2, 2', 2'') of different appearance and/or feel, and one (2) of said zones of each pair of zones (2, 2'; 2, 2'') being recessed in relation to the other zone, of arranging said treated and preformed skin (3) in a duplicate moulding mould, of acting on the or each recessed surface zone (2) with a view to displacing it to bring the ridge or each ridge (6) of this zone (2) flush with the or a corresponding ridge (6', 6'') opposite the or one of the adjacent or contiguous surface zone(s) (2', 2''), thus conferring on said skin (3) its final form, then of duplicate moulding the internal face of said skin to produce the composite part (1). |
