Sorun Belirtisi
During PETG '2079851475616104452, the material at the nozzle freezes and clogs, making normal injection impossible.
Neden Analizi
Nozzle temperature low (below the melting temperature), contact between mold and nozzle causes excessive cooling, material cools during long shutdown.
Çözüm
Increase the nozzle temperature to 240-250°C; reduce the contact area between the nozzle and the mold (insulation pad); manually purge before shutdown.
Temel Çıkarım
PETG nozzle freezing is a common problem of temperature control and thermal management.
