Improper Screw Rotation Speed in PCTG '2079851475616104452
Fenómeno del problema
Too high a screw rotation speed causes excessive shear heat and degradation, and too low a speed causes insufficient plasticization.
Análisis de la causa
The screw rotation speed is not optimized according to the characteristics of PCTG, and general parameter settings are not suitable.
Solución
Set the screw rotation speed to 50-80rpm; monitor the melt temperature to prevent overheating.
Conclusión clave
The PCTG screw rotation speed needs to balance plasticization and shear heat.
