Abstract
A method for producing an automotive equipment part includes the following steps: arranging a porous layer in a foaming mold; injection, on one side of the porous layer, of a foam precursor; expansion of the precursor material to form a foam base layer bonded to the porous layer; and extraction from the mold of the equipment part including the porous layer and the foam base layer bonded to the porous layer. The method further includes a step for injecting a pressurized fluid on a second side of the porous layer to form a counter-pressure to the expansion of the precursor material.
