The invention relates to a metal plate lower trim panel part of a hallstand of a sedan car and a manufacturing method of the metal plate lower trim panel part. The part comprises a surface carpet, a bonding layer, a forming felt layer and an improvement layer which are sequentially arranged from top to bottom. The bonding layer is used for bonding the surface carpet and the forming felt layer, the improving layer is used for improving the tensile property of the forming felt layer, and the forming felt layer is prepared from, by weight, 40-60 parts of black PET fibers, 30-50 parts of low-melting-point PET fibers and 10 parts of polypropylene fibers. The manufacturing method comprises the following steps: manufacturing the molded felt layer; coating a non-woven fabric; and heating, pressurizing and shaping. Compared with the prior art, the low-emission performance of the part is achieved, the tensile property of the formed felt layer is improved, and the risk that a part base material is pulled to be broken by the position with large local stretching is avoided.

    本发明涉及一种三厢轿车衣帽架钣金下饰板零件及其制作方法。该零件包括自上而下依次设置的表面地毯、粘合层、成型毡层、以及改善层;所述粘合层用于粘结表面地毯与成型毡层,所述改善层用于改善成型毡层的拉伸性能,所述成型毡层由重量份为(40‑60):(30‑50):10的黑色PET纤维、低熔点PET纤维、聚丙烯纤维组成。该制作方法包括制作成型毡层;涂覆无纺布;加热加压定型。与现有技术相比,本发明实现了零件的低散发性能、改善了成型毡层的拉伸性能、且避免了局部拉伸较大的位置拉破零件基材的风险。
