Severe Internal Stress Concentration of CMC
문제 현상
Internal stress of CMC products >15MPa causes cracking during storage
원인 분석
Injection speed is too fast and orientation stress is large; uneven cooling freezes thermal stress; improper gate position concentrates flow orientation
해결 방법
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
핵심 요약
Internal stress is caused by fast injection and uneven cooling; speed reduction, uniform cooling and annealing are the key
