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.
