EVA product twist deformation

문제 현상

EVA product twists 2-3°/100mm along the axis

원인 분석

Asymmetric cooling causing shrinkage differences on each face producing a twisting moment; gate position producing asymmetric flow orientation

해결 방법

1) Symmetric cooling design to ensure uniformity on all faces; 2) Symmetric gate arrangement; 3) Annealing to release twisting stress

핵심 요약

Twist deformation is caused by asymmetric cooling; symmetric cooling is key

EVA twist deformation symmetric cooling gate arrangement annealing
