Insufficient melt flowability, mold filling difficulty

Fenómeno do problema
The melt cannot fill thin-wall or complex geometry cavities
Análise das causas
Processing temperature too low (<360°C), the material is not fully melted to a low-viscosity state; PEEK grade molecular weight too high (such as medium-high viscosity injection grades); moisture affects plasticization
Solução
Increase the processing temperature to 370-390°C to improve flowability; select low-viscosity PEEK grades (such as 150G or 90G); fully dry to ensure the material state before plasticization
Conclusão principal
PEEK's high melting point determines that extremely high processing temperature and pressure are required to ensure flowability
