MP Product Elliptical Deformation
Fenómeno do problema
Ellipticity of MP circular products after demolding >1.03
Análise das causas
Asymmetric demolding force deforming the product under lateral force; non-uniform cooling with different shrinkage in each direction
Solução
1) Uniform ejection design with 8-point ejection to avoid lateral force; 2) Annular uniform cooling; 3) Extend cooling time for full setting
Conclusão principal
Elliptical deformation is caused by asymmetric demolding force; uniform ejection is key
