    • The present invention provides for an improved trim part with a multi-feel cover for use in a trim assembly, e.g. a door panel, and to a continuous two-shot molding operation that may be performed utilizing a single mold assembly. In an exemplary embodiment, a trim assembly includes a substrate having an integrated armrest and/or integrated bolster formed by injecting a first material into a first shot mold cavity in a first shot of a molding operation. A cover then is molded to at least a portion of the integrated trim part by injecting into a mold chamber a second foamed material in a second shot of the molding operation. The molded cover defines a first and second thickness with the second thickness being greater than the first thickness to provide a softer feel. The second foamed material produces an outer skin and a light, cellular inner core, within at least the second thickness of the cover, such that the skin deforms and compresses the inner core when a force is applied thereby providing a softer feel.
    • 本发明提供了一种改进的装饰部件,其具有用于装饰组件的多触感盖,例如。 门板,以及可以使用单个模具组件执行的连续两次成型操作。 在一个示例性实施例中,修剪组件包括具有集成的扶手和/或整体式枕垫的衬底,所述扶手和/或整体式枕垫通过在模制操作的第一次射出中将第一材料注射到第一射出模腔中而形成。 然后通过在成型操作的第二次射入中将第二发泡材料注入到模具室中,将覆盖件模制到集成饰边部件的至少一部分上。 模制的盖限定第一和第二厚度,第二厚度大于第一厚度以提供更柔软的手感。 第二发泡材料在至少第二厚度的外壳内产生外皮和轻细胞内芯,使得当施加力时,皮肤变形并压缩内芯,从而提供更柔软的手感。
