PCABS Low-Temperature Toughness Application
Problem Phenomenon
[Problem Phenomenon] Products in cold regions require low-temperature impact-resistant materials
Cause Analysis
PC/ABS has better low-temperature toughness than ABS, and can be used for outdoor electronics and automotive parts in cold regions; extreme cold conditions require verification; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
Select PC/ABS for cold region parts and verify low-temperature impact; toughened grades cover extreme cold; 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
Key Takeaway
PC/ABS low-temperature toughness is above average, and cold region parts can be trusted after verification; 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
