DSTDP product twisting deformation
Problem Phenomenon
DSTDP product twisted 2-3°/100mm along the axis
Cause Analysis
Asymmetric cooling causes shrinkage differences on each face producing twisting moment; gate position produces asymmetric flow orientation
Solution
1) Symmetric cooling design ensures uniformity of each face; 2) symmetric gate arrangement; 3) annealing to release twisting stress
Key Takeaway
Twisting deformation is caused by asymmetric cooling; symmetric cooling is key
