Tooling for manufacturing a vehicle panel and method of manufacture
Tooling for manufacturing a vehicle panel having a substrate, a foam layer, and a decorative covering. The tooling includes a tool base having a tool aperture, and an insert having a sealing projection. The insert is located at least partially in the tool aperture. The sealing projection is configured to create a seal between the substrate and the decorative covering at least partially around a substrate aperture in the substrate. The substrate aperture is at least partially smaller than the tool aperture so as to form an overlapping seal area between the sealing projection of insert and the substrate. A manufacturing method can create a foam-less region between the decorative covering and the substrate.
1. Tooling for manufacturing a vehicle panel having a substrate, a foam layer, and a decorative covering, comprising:
a tool base having a tool aperture; and
an insert having a sealing projection, the insert being located at least partially in the tool aperture, wherein the sealing projection is configured to create a seal between the substrate and the decorative covering at least partially around a substrate aperture in the substrate, wherein the substrate aperture is at least partially smaller than the tool aperture so as to form an overlapping seal area between the sealing projection of the insert and the substrate, wherein the substrate aperture is a locator hole for attaching a vehicle panel subcomponent, wherein the insert is a separate component from the decorative covering and the substrate.
2. The tooling of claim 1 , wherein the insert is removable with respect to the tool aperture.
3. The tooling of claim 1 , wherein a foam-less region is created between the substrate and the decorative covering at the overlapping seal area.
4. The tooling of claim 1 , wherein the sealing projection comprises a raised perimeter region, the raised perimeter region corresponding at least partially to a perimeter of the substrate aperture.
5. The tooling of claim 1 , wherein the insert has an underside and an opposite part side, and wherein a shim is located on the underside.
6. The tooling of claim 1 , wherein the substrate aperture has a tapered edge and the overlapping seal area is located at a planar inboard edge of the substrate aperture.
7. The tooling of claim 3 , wherein the sealing projection has a planar top surface configured to create the foam-less region.
8. The tooling of claim 3 , wherein the foam-less region is a 1.5-5 mm perimeter, inclusive, around the substrate aperture.
9. The tooling of claim 5 , wherein a plurality of shims is located on the underside of the insert.
10. A method of manufacturing a vehicle panel having a substrate, a foam layer, and a decorative covering, comprising the steps of:
situating the decorative covering in tooling comprising:
a tool base having a tool aperture; and
an insert having a sealing projection, the insert being located at least partially in the tool aperture, wherein the sealing projection is configured to create a seal between the substrate and the decorative covering at least partially around a substrate aperture in the substrate, wherein the substrate aperture is at least partially smaller than the tool aperture so as to form an overlapping seal area between the sealing projection of the insert and the substrate, wherein the substrate aperture is
a locator hole for attaching a vehicle panel subcomponent, wherein the insert is a
separate component from the decorative covering and the substrate;
situating the substrate over the decorative covering such that the substrate aperture of the substrate is positioned over the tool aperture in the tool base;
forming the seal between the decorative covering and the substrate around the substrate aperture by applied pressure between the substrate and the insert; and
foaming between the substrate and the decorative covering.
11. The method of claim 10 , further comprising the step of adjusting the insert with one or more shims to manage the applied pressure.
12. The method of claim 10 , wherein the seal creates a foam-less region in an overlapping seal area between the substrate and decorative covering, and wherein the forming step further comprises creating the seal using the sealing projection on the insert that forces the decorative covering into engagement with the substrate around the substrate aperture.
13. The method of claim 10 , further comprising the step of maintaining an offset between the substrate and the decorative covering before the foaming step.
14. The method of claim 13 , wherein a height of the offset is equal to half of a height of the sealing projection on the insert.
