摘要
Injection molding method of a part (6) for vehicle interiors, comprising the steps of: - arranging a mold (4) having a first injection chamber (8) shaped so as to define in negative a base (36) of said part (6), - injecting thermoplastic material, such as polypropylene, into said first injection chamber (8), - extracting the base (36) from the first injection chamber (8) and placing it in a second injection chamber (12) on the side of a functional wall (44) of said second injection chamber (12), - inserting a lining film (48) in said second injection chamber (12) and deforming it so as to arrange it, on the side of an outer surface (52) thereof, adhering to an esthetic wall (56) of the second injection chamber (12) opposite the functional wall (44), - injecting an intermediate layer (80) of plastic material, such as a thermoplastic elastomer (TPE), in a gap (84) between an inner wall (88) of the base (36) facing the lining film (48), and an inner surface (92) of the lining film (48) opposite said outer surface (52) so as to create a single sandwich structure, wherein said intermediate layer (80) is present between the lining film (48) and the base (36), - the intermediate layer (80) having lower hardness than the base (36) and forming a yielding padding for the lining film (48).
