The die includes a body provided with a plurality of polymer flow channels and a plate fixed to the front surface of the body and bored at locations corresponding to each channel. An insulating layer is positioned between the body and the bored plate. The channels include a thermoregulating system for the die body. A plurality of nozzles is provided, with the nozzles being rooted inside the die body at locations corresponding to the channels. The nozzles protrude from the body itself to cross through the insulating layer and the bored plate. The nozzles are made of a metal having a thermal conductivity higher than 60 W/m°K.
