EEA Product Twist Deformation

Problembeschreibung

EEA products twist 2-3°/100mm along the axis

Ursachenanalyse

Asymmetric cooling causes shrinkage differences on each face, producing twisting moment; gate position produces asymmetric flow orientation

Lösung

1) Symmetric cooling design to ensure uniformity on each face; 2) Symmetric gate arrangement; 3) Anneal to release twisting stress

Wichtigste Erkenntnis

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

EEA twist deformation symmetric cooling gate arrangement annealing
