Nozzle temperature affects the quality of melt entering the mold
Sorun Belirtisi
Nozzle temperature affects the quality of melt entering the mold
Neden Analizi
Nozzle temperature too low, cold slug produced and carried into the cavity during injection
Nozzle temperature too high, severe drooling, wasting material
Temperature difference between nozzle and barrel front zone too large
Nozzle heater band failure, unstable temperature
Nozzle orifice diameter and temperature not matched
Çözüm
Set nozzle temperature 5-10°C lower than the front zone
Avoid too low producing cold slug
Avoid too high causing drooling
Ensure the nozzle heater band works normally
Match nozzle orifice diameter with temperature
Temel Çıkarım
Nozzle temperature needs to coordinate with the front zone to avoid cold slug and drooling
