Method of manufacturing a seal assembly for a vehicle

1. A method of manufacturing a seal assembly for a vehicle with said method utilizing a molding apparatus defining a mold cavity, said method comprising the steps of:

extruding a first strip of material to form a first body having opposing first body ends;

extruding a second strip of material to form a second body having opposing second body ends;

positioning one of the first body ends and one of the second body ends into the mold cavity of the molding apparatus with the first body end positioned adjacent the second body end;

injecting an elastomeric material into the mold cavity to form a locator device having a foot portion and a tab portion extending from the foot portion with the tab portion defining a first reference point and with the foot portion of the locator device positioned adjacent the first body end; and

injecting a thermoplastic elastomeric material into the mold cavity to form a corner mold covering the first body end, the second body end, and the foot portion of the locator device with the corner mold defining a second reference point, and the corner mold bonding the first body end, the second body end, and the locator device together and to fix the foot portion of the locator device to the first body end at a locator position such that a predetermined distance between the first and second reference points is maintained during the injecting of the thermoplastic elastomeric material.

2. The method as set forth in claim 1 wherein the tab portion of the locator device has an aperture and the second reference point is defined at the center of the aperture.

3. The method as set forth in claim 1 wherein the corner mold has a corner with the second reference point defined on the corner and the locator position is maintained during the injecting of the thermoplastic elastomeric material by maintaining the predetermined distance between the first reference point defined on the tab portion of the locator device and the second reference point defined on the corner of the corner mold.

4. The method as set forth in claim 1 wherein the second reference point is defined on a portion of the corner mold covering the second body and the locator position is maintained during the injecting of the thermoplastic elastomeric material by maintaining the predetermined distance between the first reference point defined on the tab portion of the locator device and the second reference point defined on the portion of the corner mold covering the second body.

5. The method as set forth in claim 1 wherein the foot portion of the locator device defines at least one aperture and is spaced from the first body and during the step of injecting the thermoplastic elastomeric material into the mold cavity to form the corner mold, the thermoplastic elastomeric material flows into the aperture defined in the foot portion of the locator device and into a space between the foot portion and the first body end to interlock the locator device with the first body end.

6. The method as set forth in claim 1 wherein the step of positioning the first and second body ends in the mold cavity is further defined as positioning the first body end in a first predetermined orientation in the mold cavity and positioning the second body end in a second predetermined orientation in the mold cavity transverse to the first predetermined orientation such that the first body forms a base and the second body forms a side of an applique attachment portion of the seal assembly.

7. The method as set forth in claim 1 further comprising the steps of:

extruding a third strip of material to form a third body having opposing third body ends; and

positioning one of the third body ends into the mold cavity of the molding apparatus in a third predetermined orientation transverse to the first predetermined orientation; and

wherein the step of injecting the thermoplastic elastomeric material further comprises injecting the thermoplastic elastomeric material into the mold cavity to form the corner mold covering the first body end, the second body end, and the third body end such that that the first body forms a base, the second body forms a side, and the third body forms another side of an appliqué attachment portion of the seal assembly.

8. The method as set forth in claim 7 wherein the step of positioning the third body end into the mold cavity occurs simultaneously with the step of positioning the first and second body ends into the mold cavity.

9. The method as set forth in claim 7 further comprising the step of attaching an appliquté the locator device such that the appliquté is positioned between the second and third bodies of the appliquté attachment portion of the seal assembly.

10. The method as set forth in claim 9 wherein the locator device defines at least one alignment flange and the step of attaching the appliquté comprises utilizing the alignment flange to orient the appliquté relative to the seal assembly.

11. The method as set forth in claim 7 wherein the first and second bodies partially form a window seal portion for attachment to a window frame of the vehicle.

12. The method as set forth in claim 1 wherein the step of injecting the thermoplastic elastomeric material into the mold cavity to form the corner mold occurs after to the step of injecting the elastomeric material into the mold cavity to form the locator device.

13. The method as set forth in claim 1 wherein the first and second bodies remain in the mold cavity during the steps of injecting the elastomeric material into the mold cavity to form the locator device and injecting the thermoplastic elastomeric material into the mold cavity to form the corner mold.

14. The method as set forth in claim 1 wherein the molding apparatus has a lower die defining a lower portion of the mold cavity and the step of positioning one of the first body ends and one of the second body ends in the mold cavity is further defined as positioning one of the first body ends and one of the second body ends in the lower portion of the mold cavity.

15. The method as set forth in claim 1 wherein the molding apparatus has a lower die, a first upper die, and a second upper die and the step of injecting the elastomeric material comprises injecting the elastomeric material into the first upper die and the step of injecting the thermoplastic elastomeric material into the mold cavity comprises injecting the thermoplastic elastomeric material into the second upper die.

16. The method as set forth in claim 15 wherein step of injecting the elastomeric material into the first upper die occurs prior to the step of injecting the thermoplastic elastomeric material into the second upper die.

17. The method as set forth in claim 1 wherein the step of injecting the elastomeric material is further defined as injecting the elastomeric material utilizing a first injector, and the step of injecting the thermoplastic elastomeric material is further defined as injecting the thermoplastic elastomeric material utilizing a second injector.
