Abstract
The present invention relates to a method of injection-molding electrically shielding electronic casings, where a laminate that comprises at least one metal foil and at least one plastic layer is held stretched in an injection-molding tool. According to the invention, a plastic structure is molded in the tool on that side of the laminate which comprises the plastic layer, wherewith the laminate is deep-drawn in the tool and formed therein as the plastic material is injected thereinto and the plastic layer adheres to the plastic structure, therewith forming a molded plastic element which includes an integrated and uniformly distributed and therewith shielding metal layer.
