PA66 creep failure
Sorun Belirtisi
PA66 long-term loaded bracket sags significantly after one year
Neden Analizi
PA66 creep is significant, deformation grows with time under constant load, and temperature rise accelerates creep; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience
Çözüm
Use glass fiber reinforced grades for long-term loaded parts; design according to creep modulus; add metal reinforcement when necessary; after adjustment, take continuous samples to verify the effect, confirm stability before resuming mass production
Temel Çıkarım
Long-term load-bearing design must be checked with creep data; 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
