LDPE Film Temperature Gradient Setting
Sorun Belirtisi
The bubble is unstable after material change; it recovers after re-setting the temperature gradient according to the melting point.
Neden Analizi
The temperature gradient is not set according to the new material's melting point and rheological properties, so plasticizing and output state deviate from the optimum; blindly following the old process is a common mistake.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience.
Çözüm
①Set the temperature gradient according to material melting point; ②Verify melt temperature after material change; ③Record process cards for each grade; ④Train the material change process.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Temel Çıkarım
The temperature gradient must match material characteristics; process card management can reduce material change fluctuation.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
