OVERVIEW:
Hot Runners

hotrunners.jpg

A hot runner system is an assembly of heated components—hot halves, nozzles and gates and—that inject plastic into the cavities of an injection mold. The system usually includes a heated manifold and a number of heated nozzles. The manifold distributes the plastic entering the mold to the nozzles, which then meter it precisely to the injection points in the cavities. The hot runner is equipped with its own temperature control system.
