A transmission member of the kind comprising a floating core free to move in all directions within a casing, the floating core comprising at least two arms disposed at an angle to one another, one for supporting a driven member, the other for actuation by a driving member, and the casing comprising an internal housing with a configuration which duplicates that of the floating core. Between the floating core and the walls of the internal housing is disposed there is disposed an insulating layer of a solid elastic material. Use of the transmission member is directed, in particular, to ultrasonic assistance in compacting or drawing.

Floating core transmission member for ultrasonic assistance

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.
