ABSTRACT:
A vibration-aided feed device is operatively disposed between an injection head and a mold. A feed channel is provided between the injection head and the mold for the flow of the plasticized molding material to the mold. A part of the feed channel is defined by a distribution channel running through a connecting body. A vibrating arm extends laterally from the connecting body and a vibration generator is coupled to the vibrating arm. The resulting vibrations imparted to the plasticized molding material improves the flow and distribution of the molding material and the quality of the ultimate molded article.
