Injection Molding
2 views
Flowability decline after glass fiber reinforcement
Problem Phenomenon
Injection becomes difficult after the glass fiber content exceeds 20%
Cause Analysis
The viscosity increases sharply and the glass fiber orientation creates large resistance
Solution
Glass fiber 15-20%, chopped 3-6mm, increase the processing temperature
Key Takeaway
A trade-off between reinforcement effect and processability is needed
