PLA '2079851475616104452 Filling Difficulty
Problembeschreibung
Properly dried PLA '2079851475616104452 cannot fill completely, and raising the temperature risks degradation
Ursachenanalyse
Dried PLA has high viscosity and large pressure drop, and thin-wall long-flow filling is difficult; temperature compensation approaches the degradation zone; the gate and runner design needs enlargement to reduce flow resistance
Lösung
①Enlarge the gate and runner to reduce flow resistance; ②Appropriately increase the injection pressure; ③Fine-tune the temperature in coordination, strictly prohibit exceeding the degradation zone; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
PLA filling management focuses on structure and pressure; the temperature compensation space is narrow, and gate enlargement is the first choice; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
