Abstract
An interior trim component, such as a door panel, having an outer skin backed by a low density molded mat foam substrate and an energy absorbing foam backing is manufactured in a single mold tool in a multiple stage foaming operation in which the outer skin and a glass reinforcement mat are positioned in the mold cavity and a mold insert corresponding to the energy absorbing foam layer is mounted to the lid of the mold tool. A polyurethane precursor mixture is poured into the open mold and the lid closed to generate the low density molded mat substrate. The mold is opened and the mold insert removed and a second urethane precursor mixture is poured onto the substrate and the mold closed to generate the energy absorbing foam backing within the space of the mold cavity previously occupied by the mold insert.
