The blow molding process of high-speed blow molding machine products includes: stretching, initial blowing, and second blowing. The time of these three actions is very short, but they need to be coordinated well, especially the first two steps determine the overall distribution of materials and the quality of blow molding. Therefore, it is necessary to adjust: stretching start time, stretching speed, pre blowing start and end time, pre blowing pressure, pre blowing flow rate, etc. If possible, it is to control the overall temperature distribution of the prefabricated components. The temperature gradient of the inner and outer walls of the billet. During rapid blow molding and cooling processes, induced stress may occur on the bottle wall. For inflatable beverage bottles, it can resist internal pressure, which is beneficial, but for hot filled bottles, it ensures complete release above the glass transition temperature.
