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