Abstract
A method for forming a headliner assembly includes forming a main body blank having a periphery in a shape corresponding to a desired shape of the headliner assembly, the mold has a correspondingly shaped surface with a recess including an intermediate wall portion. The method includes introducing foam into the recess to simultaneously form at least one foam beam enclosing a selected component area, and join the at least one beam to the main body. The intermediate wall can be an accessory, and the beam may be formed to surround the component area. Additional foam application may be included to acoustically control the headliner's response to buzz, squeaks and rattles.
