Insufficient filling of PLA '2079851475616104452 (short shot)
Fenómeno del problema
The cavity is not completely filled during PLA '2079851475616104452.
Análisis de la causa
The PLA melt viscosity is relatively large and the fluidity is not as good as PP, etc.; the injection pressure and speed are insufficient; the melt temperature is low; the gate is too small.
Solución
Raise the melt temperature to 180-200°C; increase the injection pressure and speed; enlarge the gate; the mold temperature can be appropriately lowered.
Conclusión clave
PLA fluidity is the main cause of short shots.
