FEM-Based Research on Molding Parameter Analysis of the PET Beverage Bottle

Abstract:

The researched PET beverage bottle molding process was analyzed with the combination of stretch blow molding technological process of the manufacturing enterprise. The molding results would be influenced by some technological parameters. In order to study the effect of these factors on the forming properties and thickness distribution of molding bottle, the article builds the physical model and finite element model of PET bottles stretch blow molding process, and simulates stretch blow molding process by using POLYFLOW software for analyzing the thickness distribution of molding bottle. Comparing different thickness distribution under the different condition of stretch speed, pre-blowing pressure, and blowing pressure, the technological parameters were optimized, so as to achieve the goal of optimization of molding bottle.
