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. A polyurethane layer is applied onto the inverted preform (3) by spraying tool (2a) to produce the unmolded elastomer skin (8) which is then turned right-side out prior to final processing in a final mold ( 11).

A method for producing elastomer skins as lining for plastic molded articles, such as automobile dashboards, comprising: providing a working model; applying a layer of elastomer material onto said working model to form a preform having an inner side facing said working model and an outer side facing away from said working model; removing said preform from said working model; inverting said preform in at least certain regions thereof by turning said preform substantially inside out so that said inner side of the preform previously facing said working model is on the outside of said preform and said outer side is on the inside thereof; applying a polyurethane paint onto said outside of said inverted preform; providing at least one spraying tool at said outside of said preform in said inverted position; applying at least one polyurethane layer by said at least one spraying tool onto said outside of said inverted preform to form a manipulable elastomer skin having the shape of said inverted preform; removing said elastomer skin together with said layer of polyurethane paint integral therewith from said preform; and inverting said elastomer skin by turning said elastomer skin inside out so that the side thereof originally facing said preform and having said integral layer of polyurethane paint thereon is on the outside of said elastomer skin.
