Problem Phenomenon
The PET preform '2079851475616104452 cycle fluctuates between shots and sometimes suddenly extends.
Cause Analysis
Mold cooling water flow/temperature fluctuates; hot runner temperature control is abnormal; the hydraulic system fluctuates; ambient temperature changes.
Solution
Stabilize cooling water supply (chiller + flow controller); regularly check hot runner temperature control; maintain the hydraulic system.
Key Takeaway
PET preform molding cycle stability is crucial to production efficiency.
