Injection Molding
8 visualizaciones
Flowability decline after glass fiber reinforcement
Fenómeno del problema
Injection becomes difficult after the glass fiber content exceeds 20%
Análisis de la causa
The viscosity increases sharply and the glass fiber orientation creates large resistance
Solución
Glass fiber 15-20%, chopped 3-6mm, increase the processing temperature
Conclusión clave
A trade-off between reinforcement effect and processability is needed
