PVC Profile Doors and Windows
Problembeschreibung
Insufficient welded corner strength of PVC door and window profiles
Ursachenanalyse
Improper welding temperature and time caused insufficient fusion at the welded corner; 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
Calibrate welding parameters according to profile specification; sample-check welded corner strength; standardize weld bead cleaning; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Wichtigste Erkenntnis
Welded corner strength of doors and windows is guaranteed by welding parameters; 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
