发明名称 Method of producing coated molded plastic articles, and injection mold
摘要 A method of producing a composite plastic molded article having at least one layer of web material and a plastic body, includes placement of the web material between mold halves of an injection mold and deforming the web material through closing of the mold. Subsequently, negative pressure is applied on one side of the web material and/or excess pressure is applied on its other side, so that the web material bears upon a mold half. Plastic mass is then introduced into the opening mold in such a way that the feed rate of the plastic mass and the opening speed of the injection mold are coordinated with each other. Once a certain opening gap has been reached, the mold is closed and the plastic article is embossed.
