Structural characteristics of monolayer machine unit

 

Monolayer plastic wide film blowing machine unit is mainly used for producing products of LDPE, LLDPE, EVA, LDPE/LLDPE Blend. Its main structural characteristics are as follows:

1. The extruder adopts corrugated screw with mixing head and force transporting barrel, and configured with DC motor (or frequency control motor).
2. The cooling system adopts air blower with low air pressure, and large air volume.
3. The haul-off system is stable and reliable.
4. It is supported by split device.
5. The inner cooling device can be matched by the requirement of users (ordered separately).
