A hot runner system includes a having a cavity (18). Melt is fed from a source of melt into the cavity (18), and a valve (24) isolates melt in the cavity (18) from melt in the source. A plunger (34) within the cavity (18) is driven forward to inject melt in the cavity (18) into a mold cavity (26) at high pressure without significantly increasing the pressure of melt in the source. The plunger (34) optionally functions as both the plunger (34) and the valve (24) by opening and closing communication between the cavity (18) and the manifold (16) as it is rotated.

L'invention porte sur un système de canal chauffant qui comprend une cavité (18). Une masse fondue est alimentée à partir d'une source de masse fondue à l'intérieur de la cavité (18), et une soupape (24) isole la masse fondue dans la cavité (18) de la masse fondue dans la source. Un piston (34) à l'intérieur de la cavité (18) est entraîné vers l'avant pour injecter la masse fondue dans la cavité (18) à l'intérieur d'une cavité de moule (26) à une pression élevée sans augmenter de manière significative la pression de masse fondue dans la source. Le piston (34) fonctionne facultativement à la fois en tant que piston (34) et que soupape (24) par l'ouverture et la fermeture d'une communication entre la cavité (18) et le collecteur (16) à mesure qu'il tourne.
