  • Patent number: 5013508
    Abstract: A method for producing elastomer skins as lining material for plastic molded articles, such as automobile dashboards, in which a parting agent and a polyurethane system are introduced into a preform (3) taken from a working model (1) forming a manipulable, dimensionally stable elastomer skin (8), which is unmolded after completion of the reaction and finished in a final mold (11) to make a molded article for improving the process of in-mold coating such that UV-resistant elastomer skins are produced easily and absolutely dimensionally accurately, even with undercuts and narrow, deep crevices. A polyurethane paint is provided between the parting agent and the polyurethane system. Prior to the introduction of the polyurethane layer, the preform (3) is at least regionally inverted into a position in which its side facing the spraying tool (2a) is on the outside and has a substantially convex curvature.
