PET Bottle Thin Shoulder
Problembeschreibung
Shoulder wall thickness too thin, shoulder cracks on drop.
Ursachenanalyse
The lamp zone temperature corresponding to the shoulder is high or the pre-blow distributes the material to the bottle body too early; the preform shoulder wall thickness design is insufficient.
Lösung
①Lower the upper lamp zone or strengthen ventilation there; ②optimize pre-blow timing; ③evaluate the preform shoulder design.
Wichtigste Erkenntnis
Thin shoulder = upper heat + pre-blow rhythm.
