“…The increase of the preform thickness improves the thickness distribution of the bubble and decreases the height. Accordingly, the stretching increases and improves the mechanical properties of material of the finished product as demonstrated by Cosson et al [8]. The "optimal" distribution of the thickness should be obtained for ≃ 2.1 ∘ C and ≃ 4.2 mm.…”

“…The thickness of the bottle is linked to the variation of the stretch rod speed and time where the blow pressure is applied. Cosson et al [8] simulated the stretch blow molding process of PET bottles at the usual process temperature. The simulation results modeled the crystalline microstructure evolution and predicted the elastic behaviour of the final bottle.…”

The electric bubbles are a useful product made of PMMA material. They are produced by the stretch blow molding process. Thickness, which reflects the quality of the electric bubble, is a crucial parameter that deserves special attention for the molding process. In this work, finite element simulations of the stretch blow molding process are performed aiming at the determination of the preform geometry to ensure homogeneous thickness of the finished product. The geometrical parameters of the preform are optimized allowing a better homogeneity thickness compared to existing data. The predicted parameters allow the improvement of the thickness distribution. The standard deviation of the thickness is reduced to about 95% compared to the existing bubble.

“…It was hard to control the final thickness of the plastic bottle. Some blow molding methods such as the stretch-blow modling had been simulated using FEM [10][11][12][13]. They had used a preform which was controlled its thickness using the plastic injection method.…”

This research proposed the blow molding simulation method for determining of a cross-section thickness of bottles. The finite element method (FEM) was employed to simulate the extrusion blow molding process of the complex shape bottles. The full bottle shape of blow molding process had been attempted to simulate with a rectangular shape bottle for comparing with the cross-section technique. Particularly, the physical experiment of the extrusion blow molding process was performed to verify the FEM. The cross-section technique was obtained a deviation result less than the full bottle shape simulation. The average error of full bottle shape simulation was 32.35% while the cross-section simulation obtained an average error of 17.02% when they were compared with the experimental data of the blow molding process. The FEM of blow molding simulation using the cross-section technique which was developed in this research had been found the satisfactory method to determine the initial thickness of the parison flowing through the extrusion die. It was advantaged to shape dies of the extrusion blow molding process in order to achieve the complex shape of bottles.

“…By using Finite‐Element (FE) simulations, the development and testing times for the LBO process could be significantly reduced. Several workgroups already applied FE‐tools to investigate the SBM process and related forming processes . One of the key features in these simulations is the PET material characterization.…”

An innovative production process for PET bottles ad containers is analyzed in this article. Liquid Bi‐Orientation (LBO) is a liquid supported stretch blow molding (SBM), which combines the separate blowing and filling phases of conventional SBM. The process modification is mainly characterized by forming the bottle using the desired liquid product instead of pressurized air. Consequently, possible improvements evolve regarding production cycle time, energy consumption and machine footprint. To make use of these capabilities, comprehensive process understanding is required, which can be increased using numerical simulation methods. Therefore, in this article, an LBO process model is set‐up and experimentally evaluated. The model explicitly considers the fluid‐structure interaction between liquid and PET, which significantly influences the PET forming behavior. The key simulation parameters namely the strong rate and temperature dependency of PET and a realistic process parameter determination are also included. The model is evaluated using two different methods to show the reliability of the process prediction. POLYM. ENG. SCI., 55:933–944, 2015. © 2014 Society of Plastics Engineers
