<p>An injection nozzle for plastic injection moulding equipment having a nozzle tip (4) with an internal hollow element (5) made of a material with high thermal conductivity, and an external hollow element (6) made of a material with a lower thermal conductivity. The internal hollow element (5) is connected to the body (1) of the injector nozzle independently with respect to the external hollow element (6), and a space of mutual separation (19) is defined between the internal and external hollow elements (5,6). <IMAGE></p> |
