PPSU '2079851475616104452 filling difficulty
Fenómeno del problema
PPSU melt has high viscosity and the cavity is not completely filled.
Análisis de la causa
PPSU melt viscosity is extremely high (even at 380°C temperature), requiring very high injection pressure and speed.
Solución
Increase melt temperature to 360-380°C; greatly increase injection pressure; enlarge gates and runners.
Conclusión clave
PPSU high viscosity is the primary challenge of '2079851475616104452.
