摘要:
The hot runner nozzle (1) for injecting plastic material into a molding tool comprises a needle valve with a nozzle needle (19) for closing the discharge opening (25). The nozzle needle (19) has the same diameter as the cylindrical bore in the discharge opening (25) and is inserted therein in order to close the cylindrical bore in the discharge opening (25). During the injection process the nozzle needle (19) is outside the melt flow and cannot cause said melt flow to swirl and is not radially loaded by the melt flow.
