Insufficient roundness of PU
Fenómeno del problema
Roundness deviation of PU round products >0.3mm
Análisis de la causa
Uneven cooling causing different shrinkage in each direction; gate position causing local over-filling; asymmetric demolding force
Solución
1) Annular uniform cooling to ensure consistent shrinkage in all directions; 2) Symmetrical arrangement of gate positions; 3) Uniform ejection to avoid deformation
Conclusión clave
Insufficient roundness is caused by uneven cooling; annular cooling is key
