WORKING PROCESS OF HIGH SPEED BLOW MOULDING MACHINE PRODUCTS
The blowing process of High Speed Blow Molding Machine products includes: stretching-first blowing-second blowing, the time of the three actions is very short, but they must be well coordinated, especially the first two steps determine the overall distribution of the material, blowing The quality is good or bad. Therefore, it is necessary to adjust: stretching start timing, stretching speed, pre-blowing start and end timing, pre-blowing pressure, pre-blowing flow rate, etc. If possible, it is best to control the overall temperature distribution of the preform. The temperature gradient of the inner and outer walls of the billet. During the rapid blow molding and cooling process, there is induced stress in the bottle wall. For inflatable beverage bottles, it can resist internal pressure, which is beneficial, but for hot-fill bottles, it must be guaranteed to be fully released above the glass transition temperature.
How many chillers are needed for carbonated beverage blow molding machine to blow bottles?
The chiller for carbonated bottles is about 5 times larger than the chiller for water bottles. A simpler algorithm can be calculated on the basis of 1200 bottles/horse, for example: 36,000 bottles/hour can be equipped with a 30-horse water chiller. In order to ensure the stress requirements of the bottom of the carbonated bottle, the cooling time is generally 1.2 seconds, and the temperature of the bottom mold is 11 degrees. The number of lamp zones equipped with the heating furnace can refer to the configuration of the hot filling machine, and the effective heating time of the preform should not be less than 33 seconds.
