PPSU '2079851475616104452 filling difficulty
Problem Phenomenon
PPSU melt has high viscosity and the cavity is not completely filled.
Cause Analysis
PPSU melt viscosity is extremely high (even at 380°C temperature), requiring very high injection pressure and speed.
Solution
Increase melt temperature to 360-380°C; greatly increase injection pressure; enlarge gates and runners.
Key Takeaway
PPSU high viscosity is the primary challenge of '2079851475616104452.
