Injection molded part with insert film
View Patent ↗An injection molded part for a motor vehicle includes a film layer having a film main portion and a film first side portion that ends in a first film side surface, wherein the film first side portion extends from the film main portion in a direction different than a plane defined by the film main portion. The film layer also includes a film outer surface and a film inner surface disposed opposite the film outer surface. A first polymer layer is in contact with the film inner surface. A second polymer layer is in contact with the film outer surface, the film first side surface and the first polymer layer.
1. An injection molded part for a motor vehicle comprising:
a film layer having a film main portion and a film first side portion that ends in a first film side surface, wherein the film side portion extends from the film main portion in a direction different than a plane defined by the film main portion, the film layer also having a film outer surface and a film inner surface disposed opposite the film outer surface;
a first polymer layer having a first polymer top surface in contact with the film inner surface, wherein the film layer is inset into the first polymer layer and forms a step within the first polymer layer, and the film outer surface is in alignment with the first polymer layer top surface; and
a second polymer layer in contact with the film outer surface and the first polymer layer, wherein the second polymer layer extends beyond the step.
2. The injection molded part of claim 1 wherein the first polymer layer includes a first side surface which extends past the film first side surface.
3. The injection molded part of claim 2 wherein a distance between the first side surface of the first polymer layer and the film outer surface is greater than 11 mm.
4. The injection molded part of claim 1 wherein the film layer includes a film second side portion extending from the main portion in a direction different than the plane defined by the film main portion, wherein the film second side portion ends in a second film side surface.
5. The injection molded part of claim 1 wherein the film inner surface is concave and the film outer surface is convex.
6. The injection molded part of claim 1 wherein the first polymer layer includes a first transition region disposed between the main portion and the film first side portion.
7. The injection molded part of claim 6 wherein the first transition region has an arcuate profile and the film first side surface is disposed substantially at a midpoint of the first transition region of the first polymer layer.
8. The injection molded part of claim 1 wherein the first polymer layer and the second polymer layer contact each other along a plane aligned with the film outer surface and in an area adjacent the film first side surface.
9. The injection molded part of claim 1 wherein the first polymer layer is one of a polycarbonate, a polypropylene, and a nylon.
10. The injection molded part of claim 1 wherein the film layer includes a printed graphic and a translucent portion.
11. The injection molded part of claim 10 wherein the printed graphic is disposed above the main portion of the first polymer layer.
12. The injection molded part of claim 1 wherein the second polymer layer is a clear polycarbonate.
13. The injection molded part of claim 7 wherein the second polymer layer is in contact with the first transition region of the first polymer layer.
14. A component for a motor vehicle comprising:
a substrate having an outer surface that defines a step having a first surface perpendicular to a second surface;
a transparent coating; and
a film sandwiched between the substrate and the transparent coating, wherein the film has an opaque portion that matches the substrate and a translucent portion, a film first side surface, and a film second side surface, wherein the film is inset into the substrate and disposed within the step such that a film outer surface is flush with the substrate outer surface, and
wherein the substrate and the transparent coating contact each other continuously along two sides adjacent and in general alignment with the film first side surface and the film second side surface.
15. The component of claim 14 wherein a depth of the film measured from the film first side surface to a center of a film top surface is less than 10 mm and a depth measured from ends of the substrate and the transparent coating to a center of the transparent coating is greater than 11 mm.
16. The component of claim 14 wherein the substrate includes a center portion, a first side portion, and a first curved portion disposed between the center portion and the first side portion, and the film first side surface is substantially perpendicular to a tangent of the first side portion of the substrate.
17. The component of claim 14 wherein the transparent coating is in contact with a film top surface and a substrate top surface.
18. The component of claim 14 wherein the film and the substrate are substantially the same color.
19. An injection molded part for a motor vehicle comprising:
a film layer having a film main portion and a film first side portion that ends in a first film side surface, wherein the film side portion extends from the film main portion in a direction different than a plane defined by the film main portion, the film layer also having a film outer surface and a film inner surface disposed opposite the film outer surface, wherein the film inner surface is concave and the film outer surface is convex;
a first polymer layer in contact with the film inner surface, wherein the film layer is inset into the first polymer layer; and
a second polymer layer in contact with the film outer surface and the first polymer layer, and wherein the first polymer layer and the second polymer layer contact each other along a plane aligned with the film outer surface and in an area adjacent the film first side surface, and wherein the second polymer layer is not inset into the first polymer layer.
