Abstract

The use of simulation software to predict the thickness distribution in a blow molded part is becoming more widespread, thus saving considerable time and money in the product development process. For extrusion blow molding simulations, the ability to obtain an accurate final thickness prediction depends on starting with the correct parison thickness distribution. An extrusion simulation tool that incorporates the effects of parison programming, die swell and parison sag due to gravity is required to predict the correct parison thickness distribution. In this study, we compare the parison volume predicted by a finite element-based extrusion model with experimental measurements. The effects of different parison programs are investigated. The goal is to determine the level of accuracy and reliability of the extrusion model for predicting parison thickness.
