EEA Product Twist Deformation

Fenómeno do problema

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

Análise das causas

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

Solução

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

Conclusão principal

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

EEA twist deformation symmetric cooling gate arrangement annealing
