Glass Fibre product twist deformation
Problembeschreibung
Glass Fibre products twist 2-3°/100mm along the axis
Ursachenanalyse
asymmetric cooling causes shrinkage differences on each surface, producing twist torque; gate position produces asymmetric flow orientation
Lösung
1) symmetric cooling design to ensure uniformity on all surfaces; 2) symmetric gate arrangement; 3) annealing to release twist stress
Wichtigste Erkenntnis
twist deformation is caused by asymmetric cooling; symmetric cooling is key
