A hot runner injection mould includes an injection nozzle body with an injection channel enclosed by a heating jacket within an outer cover and an electrical heating element. The heating jacket is a fluid contained in a chamber between the nozzle body and the outer cover and the heater element is located beneath the cover. A claimed specific version of the mould comprises a hot runner plate (105) incorporating a chest-like body(115) with a hollow chamber (125) in which a central distribution channel (117) connected to the injection bush (111) feeds melt to distributing channels (119) supplying one or more nozzles (109). A heater (127) is located below the central distribution channel (117). |
