摘要

Mold for manufacturing a motor vehicle soundproofing assembly and associated manufacturing method The invention relates to a mold (30) for manufacturing a motor vehicle soundproofing assembly, comprising a first half-mold (32) and a second half-mold (34) defining between them an internal space, the internal space being intended to receive a first layer (14) comprising a thermoplastic material, the internal space comprising a free part (46) extending between the first layer (14) and one of the first half-mold (32) and of the second half-mold (34), the free part (46) being suitable for receiving a precursor of a foam intended to form an absorbent layer. The second half-mold (34) comprises at least one rib (56) projecting towards the first half-mold (32), each rib (56) extending along an outer contour of the internal space, each rib (56) being intended to come into contact against the first layer (14).
