Nozzle Blockage of PBT Reinforced Material
Problembeschreibung
Fibers or unmelted matter accumulate at the nozzle, causing nozzle blockage.
Ursachenanalyse
The glass fiber accumulates at the conical flow channel of the nozzle; the raw material contains unmelted high-melting-point particles; the nozzle hole diameter is too small.
Lösung
Use a larger nozzle hole diameter (≥3mm); regularly clean the nozzle; check the raw material quality.
Wichtigste Erkenntnis
PBT reinforced material nozzle blockage is a common cause of production interruption.
