PCABS Low-Temperature Embrittlement
Sorun Belirtisi
[Problem Phenomenon] PC/ABS toughness decreases in low-temperature environments
Neden Analizi
Toughness decreases at low temperatures; cracks first at notch stress concentration points; PC/ABS is better than ABS at low temperature but still needs verification; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Çözüm
Perform low-temperature impact verification for low-temperature parts; structural fillets; toughened grades; 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
Temel Çıkarım
PC/ABS low temperature requires verification, with fillets and toughening as 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 in the future
