PC/ABS low-temperature toughness
Problem Phenomenon
Brittle cracking in low-temperature environment.
Cause Analysis
Toughness decreases at low temperature; notch sensitivity is amplified.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
①Select high-toughness grade; ②avoid sharp corners; ③low-temperature test verification; ④round the structure.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Low-temperature applications verify first; structural design cooperates.; 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
