CEF product elliptical deformation
Fenómeno do problema
The ovality of the CEF round product after demolding is >1.03
Análise das causas
The demolding force is asymmetric and the product is deformed by lateral force; the cooling is uneven and the shrinkage is anisotropic
Solução
1) Uniform ejection design, 8-point ejection to avoid lateral force; 2) Annular uniform cooling; 3) Extend the cooling time for sufficient sizing
Conclusão principal
Elliptical deformation is caused by asymmetric demolding force; uniform ejection is the key
