Abstract
A method for forming a vehicle headliner comprises providing at least one layer of formable material and a cover member; heating the layer and the cover member; providing a mold having a pair of mold halves and a compressible seal disposed between the mold halves, at least one of the mold halves having an aperture and a channel in communication with the aperture; positioning the layer and the cover member between the mold halves; bringing the mold halves toward each other to effect a sealed relationship; and applying a vacuum pressure to the aperture to sufficiently draw the mold halves together and compress the seal, thereby compressing the at least one layer and the cover member together to form the headliner.
