POM Fatigue Fracture
ظاهرة المشكلة
POM snaps fracture at the root after repeated use
تحليل الأسباب
Stress concentrates at the snap root, and fatigue accumulates under cyclic bending; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
الحل
Enlarge root fillet; limit assembly/disassembly angle; verify by fatigue life testing; 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
الخلاصة الأساسية
Snaps are designed and verified by fatigue life; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
