Molded painted plastic component being an integrally formed badge
View Patent ↗A method is provided for manufacturing a painted plastic component having a badge, emblem or other ornamentation, such as air bag covers having a badge, or wherein the component is the badge itself. The method includes providing 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.
1. A molded painted plastic component being an integrally formed badge, the component comprising:
a formed, prepainted film sheet having top and bottom surfaces defining a badge, the film sheet being selected from the group consisting of polyester, polycarbonate, and polyurethane; and
a thermoplastic elastomer which forms a structural carrier bonded to the bottom surface of the film sheet to form a unitary laminate painted plastic component and badge wherein the film sheet comprises a layer of acrylic color and polyvinylidine fluoride and an acrylic clear coat.
2. The plastic component of claim 1 , wherein the thermoplastic elastomer is selected from the group consisting essentially of a thermoplastic polyolefin, thermoplastic urethane, polyester, polycarbonate, acrylonitrile/butadiene/styrene, polypropylene, a mixture of acrylonitrile/butadiene/styrene and polycarbonate, and mixtures thereof.
3. The plastic component of claim 1 , wherein the film sheet has a total thickness of 0.2 mils.
4. The plastic component of claim 1 , wherein the structural carrier has a flexural modulus in the range of 15,000 to 400,000 psi.
5. The plastic component of claim 1 , wherein the structural carrier has a durometer in the range of 15 Shore D to 100 Shore D.
6. The plastic component of claim 1 , wherein the polyvinylidine fluoride comprises more than 50% of the total thickness of the film sheet.
