  Abstract

The combination of stretching and blowing in ISBM (Injection Stretch Blow Molding) is the formation mechanism of plastic hollow beverage containers. This study curries the numerical effort of tracking the role of combination of stretching and blowing on the wall thickness distribution of 1.5Lt Polyethylene Terephthalate (PET) bottle. The numerical schedule of this study consists of five test cases where the engagement of pre-blowing pressure with stretching takes place at 0-100 % of the stretching rod route. It was found that with the delay of pre-blowing pressure in relation to the effect of stretching, more material is accumulated at the lower region of the final product. The most optimum cases for thickness uniformity is the case where the pre-blowing pressure activation commence at the 75 % of the stretching rod route and at the case where the pre-blowing is activated after stretching.
