Sorun Belirtisi
Melt drools from the nozzle of the PET '2079851475616104452 machine during mold opening and material charging, affecting the next shot.
Neden Analizi
Nozzle temperature is too high and melt viscosity is too low; nozzle hole diameter is on the large side; back pressure is set improperly; PET melt thermal stability is insufficient.
Çözüm
Reduce nozzle temperature to 260-270°C; use a needle valve shut-off nozzle; reduce nozzle hole diameter; use an anti-drooling program.
Temel Çıkarım
PET nozzle drooling affects production stability.
