Abstract: In a method of producing injection-molded parts, an injection mold has two mold halves and a melt feeding device for application of melt across the mold surface of a mold half, when the injection mold is open. The melt is pressed into all areas of the mold cavity, when closing the mold halves. In order to simplify the arrangement of the hot runners in the mold half, when different injection-molded parts are produced, it is proposed to apply the melt onto the mold surface by a hot runner plate which is positioned above the mold surface, whereby the hot runner plate has several melt nozzles in the form of needle seal nozzles which are operated and controlled depending on the profile required for the respective mold half.
