PP Weld Line Bubbles
Problembeschreibung
【Problem Phenomenon】Bubbles gather at PP weld lines
Ursachenanalyse
Confluence entrapped air plus venting end effect; more obvious when damp; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Lösung
Strengthen venting in weld line areas; dry damp material; optimize confluence position; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Wichtigste Erkenntnis
For PP weld line bubbles check venting and moisture; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
