  • Description
  •   The seven-layer co-extrusion blown film production line consists of five single-screw extruders and auxiliary machines.
      1. The host computer adopts frequency converter for stepless speed regulation control;
      2. The die adopts the international advanced new cone-shaped streamline superposition technology;
      3. The traction system adopts horizontal ±360° reciprocating rotation;
      4. The IBC system uses ultrasonic to control bubble internal cooling, and is equipped with a new type of electric squirrel cage stabilization bubble holder;
      5. Ultrasonic automatic correcting device;
      6. Full tension control system (using taper calculation);
      7. The control system adopts PLC centralized control technology.
