PAI melt mold filling difficulty
Fenómeno del problema
PAI still has very high viscosity and poor flowability in the molten state
Análisis de la causa
Viscosity high when processing temperature is below 340°C; mold temperature low
Solución
Increase the melt temperature to 360-380°C; keep the mold temperature high at 200-230°C
Conclusión clave
The temperature and pressure required for PAI processing are second only to PI
