Glass Fibre severe internal stress concentration
Sorun Belirtisi
Glass Fibre product internal stress >15MPa, causing storage cracking
Neden Analizi
Injection speed too fast, orientation stress large; uneven cooling freezes thermal stress; gate position improper, flow orientation concentrated
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; speed reduction, uniform cooling and annealing are key
