ABS low temperature embrittlement
ظاهرة المشكلة
[Problem Phenomenon] ABS low temperature toughness decreases and cracks
تحليل الأسباب
Low temperature toughness reduced; notch stress concentration cracks first; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry materials and should be confirmed first during troubleshooting
الحل
Low temperature impact verification; structural fillet; toughened grade; after adjustment, continuously sample to verify the effect, resume mass production only after confirming stability; change only one variable each time and record parameter changes to facilitate locating effective measures
الخلاصة الأساسية
ABS low temperature must be verified, fillet and toughening are double insurance; 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 later
