Advantages of preform injection
1. Double linear guide rail design, stable operation;
2. The closed-loop control of injection rate improves the accuracy of injection;
3. Servo motor drives plasticization;
4. Single cylinder injection improves the stability of injection process;
5. Direct feeding pipe design is adopted;
6. Pneumatic control of silo closing;
7. Temperature control detection and independent heating of each section of the barrel can meet the process requirements.
Inspection method of bottle blank quality
