ABSTRACT:
An injection molding shooting pot shot size control apparatus is configured to be installed in a coinjection hot runner with a coinjection nozzle, the coinjection nozzle having at least two melt channels ending at the same gate includes a valve inlet and a valve outlet. An adjustable melt control mechanism, preferably in the form of a hydraulically actuated wedge, is configured to (i) be disposed in a cavity plate adjacent to a hot runner assembly, and allow the shot size position to be set while the mold is open, and (ii) permit the charged shooting pot cylinder to decompress the melt when the wedge is pulled away from the shooting pot piston.
