PET Bottle Uneven Wall Thickness
Sorun Belirtisi
The bottle body is locally too thin, top load strength is insufficient, and stacking deformation occurs.
Neden Analizi
Uneven heating temperature field makes the stretching degree of each zone different; preform wall thickness design/concentricity problems; stretch rod offset or improper blowing timing.
Çözüm
①Use the wall thickness distribution map to back-calculate and adjust the power of each lamp zone; ②check preform concentricity; ③calibrate stretch rod concentricity and speed; ④stabilize high-pressure blowing pressure.
Temel Çıkarım
The wall thickness distribution map is the navigation map of the '2079851475616104457 machine.
