Twisting deformation of PU products
Sorun Belirtisi
PU products twist 2-3°/100mm along the axis
Neden Analizi
Asymmetric cooling causes shrinkage differences on each face, producing twisting moment; gate position produces asymmetric flow orientation
Çözüm
1) Symmetric cooling design to ensure uniformity of each face; 2) Symmetrical gate arrangement; 3) Annealing to release twisting stress
Temel Çıkarım
Twisting deformation is caused by asymmetric cooling; symmetric cooling is key
