Injection Molding

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