PCL screw and plasticization
Problembeschreibung
PCL screw plasticization is poor or shear is excessive, and melt quality is unstable.
Ursachenanalyse
PCL high viscosity plasticization demand; screw design; rotation speed and back pressure; temperature distribution; wear influence.；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Lösung
①Screw design adaptation; ②Rotation speed and back pressure optimization; ③Uniform temperature distribution; ④Wear inspection.；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
PCL plasticization quality depends on the screw and parameters; uniformity is the goal; maintenance ensures stability.；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
