发明名称 SPRING SUPPORT AND METHOD FOR PRODUCING THE SAME
摘要 A spring support, particularly for a spring hanger of a motor vehicle, comprises an annular retaining element made of a thermoplastic material and a spring support element made of an elastomer material applied to the retaining element. The retaining element comprises at least one closed hollow space. A method is provided for producing such a spring support, wherein the method comprises introducing a melt of a thermoplastic material into an injection mold including at least two mold cores for configuring at least two through-openings in the thermoplastic material, injecting an expansion material for configuring a closed hollow space in the melt of the thermoplastic material and applying an elastomer material to the thermoplastic material. During injection of the expansion material, the mold cores are cooled and the expansion material is injected into at least two regions of the thermoplastic material separated from each other by the mold cores, in order to implement one closed hollow space in each of the regions.
