Sorun Belirtisi
The transverse thickness of the PBT extruded sheet fluctuates, affecting subsequent stamping or '2079851475616104458.
Neden Analizi
The die lip gap is uneven; the melt temperature distribution is uneven and the viscosity differs; the three-roll gaps are not parallel.
Çözüm
Precisely adjust the die lip gap; optimize the barrel temperature uniformity; calibrate the three-roll gap.
Temel Çıkarım
The thickness uniformity of PBT sheet is the basis for subsequent processing.
