PA6 Cable Tie Selection
Problem Phenomenon
Outdoor equipment cable ties brittlely fracture and fail in less than a year
Cause Analysis
Outdoor ultraviolet and dry-wet cycling accelerate PA6 aging; at dry-state low temperature, cable ties are notch-sensitive and brittlely fracture, and ordinary natural-colored material has insufficient weather resistance; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
Select carbon black UV-resistant grades for outdoor cable ties; select toughened grades for low-temperature environments; replace with PA66 or metal cable ties for high bundling force occasions; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
Cable tie failure is mostly aging brittle fracture, and outdoor and low-temperature use requires dedicated selection; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
