PA66 ski bindings
Problem Phenomenon
Ski bindings crack under impact at low temperature
Cause Analysis
Ski resort low temperature plus high-speed impact, ordinary PA66 has insufficient low-temperature toughness; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry materials and should be confirmed first during troubleshooting
Solution
Select low-temperature toughened special grades; test according to -30℃ low-temperature impact; metal composite design for critical load-bearing parts; after adjustment, take continuous samples to verify the effect, confirm stability before resuming mass production
Key Takeaway
Low-temperature sports equipment must use low-temperature toughened grades; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
