ABSTRACT:
A method for manufacturing an injection molded article on a surface on which a label is arranged and a device for manufacturing the injection molded article on the surface of which the label is arranged are disclosed. In the disclosed method, an injection mold is provided having two mold halves together defining a mold cavity in a closed situation. The mold cavity has a form that corresponds to a form of the injection molded article. A label is placed in the mold cavity in an open situation. The label is electrostatically charged such that it adheres electrostatically to a wall of the mold cavity. The mold cavity is closed, and a heated and thus plasticized plastic is injected into the closed mold cavity. The mold is opened after cooling and the article is removed from the mold cavity. The disclosed device includes a carrier for carrying and electrically charging the label at the moment it contacts the wall of the open mold cavity. The carrier includes an electrically conductive layer positioned between the carrier and the label and a surface of the label contacts a surface of the electrically conductive layer.
