Patent abstract
A hot runner system including a shoot pot system for transferring melt from a single shooting pot to multiple nozzles. Melt is fed from a source of melt into the cavity through the multiple nozzles, and a valve isolates melt in the cavity from melt in the source. A plunger within the cavity is driven forward to inject melt in the cavity into a mold cavity at high pressure without significantly increasing the pressure of melt in the source. The plunger optionally functions as both the plunger and the valve by opening and closing communication between the cavity and the manifold as it is rotated.
