EMA '2079851475616104452 Warpage
문제 현상
EMA injection molded products warp 2-3mm/100mm after demolding, flatness not up to standard
원인 분석
EMA shrinkage rate large and mold temperature uneven, causing shrinkage differences in each direction; improper gate position, uneven release of flow orientation stress; insufficient cooling time
해결 방법
1) Increase mold temperature to 40-60°C to reduce temperature differences; 2) Increase holding pressure to 50-70MPa; 3) Optimize gate position for uniform flow; 4) Extend cooling time; 5) Annealing treatment to release residual stress
핵심 요약
Warpage is caused by shrinkage differences and orientation stress; uniform mold temperature and holding are key
