Abstract
A method is provided for manufacturing a painted plastic component such as painted air bag covers, side cladding or exterior bumpers, which includes a painted film sheet and a one-piece thermoplastic elastomeric structural carrier. A bottom contact surface of the film sheet bonds with a front contact surface of the structural carrier by diffusion between the contact surfaces thereof within a mold cavity of an injection mold separate from the mold cavity of a vacuum mold which is utilized to vacuum-mold the film sheet to form the desired painted plastic component.
Claims10
A method of manufacturing a molded plastic component, comprising:
- providing a film sheet having top and bottom surfaces, the film sheet being selected from the group consisting of polyester, polyurethane and polycarbonate;
- vacuum molding the film sheet in a mold cavity to obtain a pre-form;
- placing the pre-form in a mold cavity of an injection mold having a shape defining the desired plastic component;
- and
- injecting a thermoplastic elastomer into the mold cavity of the injection mold to generate a structural carrier for the pre-form, the generation of the structural carrier creating sufficient pressure and heat to bond the structural carrier to the bottom surface of the pre-form to form the molded laminate plastic component wherein the film sheet is coated with a layer of acrylic color and a layer of polyvinylidine fluoride and an acrylic clear coat layer.
A method of manufacturing a molded laminate automotive component, comprising:
- inserting a film sheet into a vacuum forming station to form the film sheet into a predetermined automotive component shape to create a formed film sheet having top and bottom surfaces, the film sheet being selected from the group consisting of polyester, polyurethane and polycarbonate;
- placing the formed film sheet in a mold cavity of an injection mold having a shape defining the automotive component;
- injecting a thermoplastic elastomer into the mold cavity of the injection mold, such that the thermoplastic elastomer is in mating contact with the bottom surface of the formed film sheet, to generate a structural carrier for the formed film sheet, the generation of the structural carrier creating sufficient pressure and heat to bond the structural carrier to the bottom surface of the formed film sheet to form the molded laminate automotive component wherein the film sheet is coated with a layer of acrylic color and a layer of polyvinylidine fluoride and an acrylic clear coat layer.
