PPO Product Assembly Whitening
Problembeschreibung
[Problem Phenomenon] Whitening at snap-fit assembly locations of PPO products, traces of stress concentration
Ursachenanalyse
Assembly interference and snap-fit deformation produce stress whitening; PPO is sensitive to stress whitening, indicating local stress exceeding the limit; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Lösung
Optimize snap-fit design to reduce assembly stress; review the interference amount at whitened locations; select toughened grades if necessary; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
PPO assembly whitening is a stress alarm, and snap-fit design needs review; after confirming effectiveness, solidify 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
