PLA '2079851475616104452 Filling Difficulty
Sorun Belirtisi
Properly dried PLA '2079851475616104452 cannot fill completely, and raising the temperature risks degradation
Neden Analizi
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
Çözüm
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
Temel Çıkarım
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
