Abstract
An automotive vehicle includes a body with a front portion and a rear portion. The vehicle additionally includes a spoiler coupled to the rear portion. The spoiler includes a first portion, a second portion, and a cap. The first portion includes a first plastic material, the second portion includes a second plastic material, and the cap includes a third plastic material. The second plastic material is distinct from the first plastic material. The second portion is disposed between the first portion and the cap. The second portion has a through hole extending therethrough. The cap has a diameter exceeding that of the through hole. The first portion and the cap are welded together via the through hole to mechanically secure the second portion to the first portion.
Claims20
An automotive vehicle comprising:
- a body having an exterior portion;
- and
- a spoiler coupled to the exterior portion, the spoiler including a first portion comprising a first plastic material, a second portion comprising a second plastic material, and a cap comprising a third plastic material, the second plastic material being distinct from the first plastic material, the second portion being disposed between the first portion and the cap and having a through hole, the first portion and the cap being welded together via the through hole to mechanically secure the second portion to the first portion.
A method of manufacturing a multi-piece plastic component, the method comprising:
- providing a first component including a first plastic material;
- providing a second component including a second plastic material, the second component having a hole extending therethrough, the second plastic material being distinct from the first plastic material;
- providing a cap including a third plastic material;
- assembling the cap over the hole;
- and
- welding the cap to the first component via the hole to mechanically secure the second component to the first component.
An apparatus comprising:
- a first plastic component having a first material composition;
- a second plastic component having a second material composition, the second material composition being weld-incompatible with the first material composition, the second plastic component having at least one through hole extending therethrough;
- and
- a cap having a third material composition, the third material composition being weld-compatible with the first material composition, the second component being disposed between the first component and the cap, the first component and the cap being welded together via the through hole to mechanically secure the second component to the first component.
