EAA product elliptical deformation
문제 현상
EAA circular products with ellipticity >1.03 after demolding
원인 분석
Asymmetric demolding force, product deformed by lateral force; uneven cooling, different shrinkage in all directions
해결 방법
1) Uniform ejection design with 8-point ejection to avoid lateral force; 2) Annular uniform cooling; 3) Extend cooling time for full setting
핵심 요약
Elliptical deformation is caused by asymmetric demolding force; uniform ejection is key
