Simulation on Effect of Preform Diameter in Injection Stretch Blow Molding

Advances in Polyethylene Terephthalate Beverage Bottle Optimization: A Mini Review

“…Lontos and Gregoriou [98] considered three different preform lengths in order to explore the influence of preform length on the wall thickness distribution of the final product and found that the bottom area of the bottle made of the longer preform length was thicker, which enhanced the overall stability. In order to minimize the wall thickness and reduce the use of PET, Tan et al [99] used ANSYS Polyflow to evaluate the wall thickness distribution of PET bottles with different diameters of initial bottle blanks and determined that the allowable wall thickness of preforms with at least 6 mm diameter can be 1.3 mm. Sidorov et al [100] established the relationship between the diameter, wall thickness and the length of forming zone of billet and product, and believed that the most acceptable diameter of billet should be within 30% of the diameter of the finished product.…”

“…Although this method is effective, it still has the following obvious disadvantages: uct and found that the bottom area of the bottle made of the longer preform thicker, which enhanced the overall stability.

Another reason is that the liqu caused by rupture mostly occurs at the bottom of the bottle.…”
