PET bubble cause troubleshooting
Problembeschreibung
PET sheet bubbles appear at random positions with varying sizes
Ursachenanalyse
Random bubbles are mostly due to moisture fluctuations or entrained air; fixed-position bubbles point to local overheating degradation; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Lösung
Measure moisture content to rule out the moisture factor; check feed throat negative pressure air entrainment; for fixed positions, check local overheating of the barrel; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
Bubbles are routed to troubleshooting directions according to position characteristics; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
