How to Address Uneven Wall Thickness in Stretch-Blow Molding ...

• Preform is bent before entering the blow mold. This is an issue that occurs more frequently in single-stage stretch-blow molding and has a different cause there. In two-stage it may happen when the preform wall thickness is uneven by more than 0.004 in. This leads to uneven heating—i.e., the thinner side gets hotter, and this side may then shrink more than the cooler side between the ...
