Glass Fibre poor plasticization
Problem Phenomenon
Glass Fibre products show unmelted particles, incomplete plasticization
Cause Analysis
screw compression ratio insufficient <2.5, plasticization pressure low; screw rotation speed low, insufficient shear; processing temperature low
Solution
1) select a screw with compression ratio >3; 2) increase screw rotation speed to increase shear; 3) raise processing temperature by 5-10°C
Key Takeaway
poor plasticization is caused by improper screw design; optimizing the screw and raising temperature is key
