LDPE Die Temperature
Sorun Belirtisi
In LDPE cast film, local die output is uneven.
Neden Analizi
Uneven die temperature makes output flow rates different; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; This mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting.
Çözüm
Calibrate each die temperature zone; adjust die lip gap; regular cleaning; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; Change only one variable at a time and record parameter changes to facilitate locating effective measures.
Temel Çıkarım
Cast film uniformity relies on die temperature zone management; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; Incorporate this case into the defect archive as a troubleshooting reference for similar future problems.
