TZM intenal heated hot runner systems compared to TZM externally heated hot runner systems have following features:
1. In TZM intenal heated hot runner systems, flow channel on the outer wall of the plastic layer of condensation, due to the poor thermal conductivity of plastics, flow channel stiffened good insulation effect, so that the temperature of the lower manifold, generally only 40 to 60 ℃, so the heat of hot runner systems have a "cold runner system," said. TZM heat loss heat hot runner system is small, general electric power consumption of less than 50% TZM externally heated hot runner system.
2. In TZM intenal heated hot runner systems, because of the low temperature manifold, almost without regard to the low thermal expansion, to design and install a great convenience.
3. In TZM intenal heated hot runner systems, due to condensation layer can flow channel stiffened good self-sealing effect, resulting in leakage of small melt.
4. TZM heat hot runner manifold system and other templates are fit, so the entire Vice die stiffness, but also can reduce the overall height of the mold.
