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.

How many chillers do carbonated beverage blow molding machines require to blow bottles?

The cooler of carbonated beverage bottles is about 5 times larger than that of water bottles. Taking 1200 bottles/horse as an example, a simpler algorithm can be used to calculate that 36000 bottles/hour can be equipped with a 30 horse water cooler. To ensure the stress requirements at the bottom of the carbonation bottle, the cooling time is generally 1.2 seconds, and the temperature of the bottom mold is 11 degrees. The number of light zones equipped in the heating furnace can refer to the configuration of the hot filling machine, and the effective heating time of the bottle preform should not be less than 33 seconds.
