POE internal stress concentration severe
Sorun Belirtisi
POE product internal stress >15MPa causing cracking during storage
Neden Analizi
Injection speed too fast, orientation stress large; uneven cooling freezes thermal stress; improper gate position concentrates flow orientation
Çözüm
1) Reduce injection speed to reduce orientation; 2) Uniform mold temperature to reduce thermal stress; 3) Anneal 80°C/4h to release stress; 4) Optimize gate position
Temel Çıkarım
Internal stress is caused by fast injection and uneven cooling; reducing speed, uniform cooling and annealing are key
