ABSTRACT:
A hot runner system for injecting precise quantities of at least one resin advancing under pressure from a resin source wherein the system includes a shooting pot having a piston with opposed working surfaces which divide the shooting pot into at least two reservoirs. Resin under pressure is switched cyclically from one reservoir to the other whereby the piston is driven by resin under pressure to purge one reservoir while the other reservoir is loaded.
