DSTDP product elliptical deformation
Fenómeno del problema
DSTDP round product ellipticity >1.03 after demolding
Análisis de la causa
Asymmetric demolding force, product deforms under lateral force; uneven cooling, shrinkage differs in each direction
Solución
1) Uniform ejection design, 8-point ejection to avoid lateral force; 2) annular uniform cooling; 3) extend cooling time for full setting
Conclusión clave
Elliptical deformation is caused by asymmetric demolding force; uniform ejection is key
