Material spouting from the vent vacuum port of PCTG extruder
Fenómeno del problema
Melt spouting occurs in the vacuum zone of the vent port.
Análisis de la causa
The vent port is located in a high-pressure zone; high screw filling degree extrudes the melt out.
Solución
Adjust vent port position; reduce screw rotation speed; optimize the temperature of that section.
Conclusión clave
PCTG vacuum port spouting is related to screw design.
