Improper blowing pressure, time, and speed settings affecting container quality
Problem Phenomenon
Improper blowing pressure, time, and speed settings affect container quality
Cause Analysis
Insufficient blowing pressure, container not fully expanded
Blowing time too short, uneven wall thickness
Blowing speed too fast, container locally too thin
Blowing pressure too high, container deforms or bursts
Improper switching between pre-blowing and main blowing
Solution
Reasonably set blowing pressure 0.5-1.0MPa
Extend blowing time to ensure full expansion
Control blowing speed to avoid being too fast
Avoid excessive blowing pressure
Optimize switching between pre-blowing and main blowing
Key Takeaway
Blowing process needs reasonable pressure and time settings
