Die for hot die face cutting thermoplastic polymers comprising:
- a body (6) provided with plurality of channels (5) for polymer flow;
- a plate (2) fixed to the front surface of said body (6) and bored in correspondence to each channel (5);
- an insulating layer (3) positioned between the body (6) and the bored plate (2);
- a thermoregulating system (4) for the die body (6), and
- a plurality of nozzles (1), each rooted inside the die body (6) in correspondence to each channel (5) and protruding from the body itself so as to cross the insulating layer (3) and the bored plate, (2) made of metal having thermal conductivity higher than 60 Wm DEG K. |
