ABS barrel temperature gradient
Sorun Belirtisi
ABS barrel temperature gradient setting, segmented control from feeding to nozzle.
Neden Analizi
ABS barrel temperature gradient; feeding zone, compression zone, metering zone, nozzle segmentation; nozzle 200-230°C slightly lower than barrel to prevent drooling; gradient affects plasticization and degradation; uniformity management.
Çözüm
①Appropriately low temperature in feeding zone; ②gradient temperature increase in compression and metering zones; ③nozzle 200-230°C; ④prevent drooling; ⑤gradient verification.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
ABS barrel gradient is fine temperature control; nozzle slightly lower to prevent drooling; verification ensures plasticization quality.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
