EVA product twist deformation
Sorun Belirtisi
EVA product twists 2-3°/100mm along the axis
Neden Analizi
Asymmetric cooling causing shrinkage differences on each face producing a twisting moment; gate position producing asymmetric flow orientation
Çözüm
1) Symmetric cooling design to ensure uniformity on all faces; 2) Symmetric gate arrangement; 3) Annealing to release twisting stress
Temel Çıkarım
Twist deformation is caused by asymmetric cooling; symmetric cooling is key
