Abstract


One of the most classical methods of producing plastic bottles which are commonly made from polyethylene terephthalate (PET) is the stretch blow molding (SBM). A new manufacture procedure of the SBM machine is designed in this paper for getting better quality of the PET bottles. The main idea of this new method focuses on providing both heating and cooling. The implements of the idea rely on the software package COMSOL 5.2a. Subsequently, four validate experiments were conducted to see the advantages of the improved system, as a result, the temperature distribution of performs is satisfied. Moreover, the energy consumption during heating is 10% less than that of the original manufacture procedure. As another advantage, the developed method not only reuses the residual energy of the cooling gas but also increases the unit time production of the machine for 5% indicating an improved efficiency in heating, thanks to the residual energy of the cooling gas.

6 Conclusions


On the whole, the major point for operating the SBM machine is how to control the heating system, the cooling system, and the production speed, in order to optimize the temperature distribution on the preform surface. The goal of the SBM machine is to provide a homogeneous thickness for the bottle. In this study, four experiments on Figs. 4, 5, 6, 7, 8, 9, 10, and 11 showed that this cooling system is very important for helping the SBM machine to optimize the temperature distribution of the PET like Fig. 9 and also makes a temperature profile along the length of the preform, shortens the heating time, and saves 10% (in Table 3) of the energy consumption. Moreover, the reusing cooling gas will cool down the temperature of the machine 10 °C. This is helpful for the machine to be capable of operating in a longer time period. The result of this paper encourages us to analyze how to multiply the cooling system, and lamps heating in order to develop the desired temperature distribution for the PET. We will therefore continue to study more about the interior temperature distribution of the bottle in the near future.
