EVA product twist deformation
Fenómeno del problema
EVA product twists 2-3°/100mm along the axis
Análisis de la causa
Asymmetric cooling causing shrinkage differences on each face producing a twisting moment; gate position producing asymmetric flow orientation
Solución
1) Symmetric cooling design to ensure uniformity on all faces; 2) Symmetric gate arrangement; 3) Annealing to release twisting stress
Conclusión clave
Twist deformation is caused by asymmetric cooling; symmetric cooling is key
