ABSTRACT OF THE DISCLOSURE The invention relates to a process and a device for the production of shaped bodies of plastic material, in particular polyurethane foam, in molds introduced into an inductor. A process of this type comprises the improvement that for the production of shaped bodies of plastic material, in particular of polyurethane foam or of fibers, non-woven fabrics or the like impregnated or wetted with synthetic resins, latex or the like, of the reactive starting materials introduced into the molds, a frequency of 1 -to 30 kHz preferably 5 to 12 kHz, is adjusted and that molds are used in which the individual mold parts are mutually electrically insulated in order to prevent a current flow in the mold around the shaped body and that optionally reinforcements or coating pieces of a material optionally identical to the material of the mold are formed on or applied to the outsides of metallic mold walls for the distribution of the current flow.
