Gate freezing blockage in PLA '2079851475616104452
Fenómeno del problema
PLA at the gate cools and crystallizes too fast, causing blockage.
Análisis de la causa
The temperature of the mold gate area is low (<60°C), and PLA crystallizes and solidifies prematurely, blocking the gate.
Solución
Raise the mold temperature in the gate area; increase the gate size; appropriately increase the injection speed.
Conclusión clave
PLA gate freezing is related to low-temperature crystallization.
