• Subjects: AFTER-TREATMENT OF THE SHAPED PRODUCTS, e.g. REPAIRING; PERFORMING OPERATIONS; SHAPING OF MATERIAL IN A PLASTIC STATE, NOT OTHERWISE PROVIDEDFOR; SHAPING OR JOINING OF PLASTICS; TRANSPORTING; WORKING OF PLASTICS; WORKING OF SUBSTANCES IN A PLASTIC STATE, IN GENERAL

The method comprises the following steps: - depositing of a porous layer (12) in a foaming mould; - injection, on one side of the porous layer (12), of a foam precursor, - expansion of the precursor material to form a layer made of foam bonded to the porous layer (12); - extraction from the mould of an equipment part comprising the porous layer (12) and the layer made of foam bonded to the porous layer (12). The method comprises a step of injecting a pressurized fluid on a second side of the porous layer (12) to form a counter-pressure to the expansion of the precursor material. 该方法包括以下步骤：将多孔层(12)置于起泡模具中；在所述多孔层(12)的侧上注入泡沫前体；膨胀所述前体材料以形成粘合到所述多孔层(12)的泡沫基层；从所述模具提取设备零件，所述设备零件包括所述多孔层(12)和粘合到所述多孔层(12)的所述泡沫基层；所述方法包括在所述多孔层(12)的第二侧上注入加压流体以形成抵抗所述前体材料的膨胀的背压的步骤。
