Abstract
The invention relates to a method for producing a plastic molded part (9) comprising an integrated conductor path (3), which plastic molded part is used in particular as an intermediate product to be further processed into an electrically heatable mirror (1). The method steps are: a) producing a substrate (7) from a carrier body (2) made of an electrically insulating plastic material having a conductor path (3) made of an electrically conductive material on or in a surface (8) of the carrier body (2), b) flooding the surface (8) of the substrate (7) equipped with the conductor path (3) or the surface (11) of the substrate (7) opposite said surface with a liquid, electrically insulating coating material. The flooding evens out depressions due to uneven shrinkage in the thick and thin areas of the carrier body and a smooth surface can be produced, which can subsequently be covered with a reflective layer.
