Film transverse and longitudinal thickness fluctuation exceeds standard
Sorun Belirtisi
Film transverse and longitudinal thickness fluctuation exceeds standard
Neden Analizi
Improper die lip gap adjustment, transverse thickness fluctuation
Unstable haul-off speed, longitudinal thickness fluctuation
Screw output fluctuation, thickness changes over time
Uneven cooling roll temperature, transverse cooling differences
Uneven die temperature distribution, transverse melt viscosity fluctuation
Çözüm
Precisely adjust the die lip gap to ensure transverse uniformity
Stabilize haul-off speed
Stabilize extrusion output
Uniform cooling roll temperature
Uniform die temperature distribution
Temel Çıkarım
Film thickness requires stable die lip gap and speed
