With the continuous progress of technology and the expansion of production scale, PET blowing machines are becoming more and more automated, and the production efficiency is getting higher and higher. The production capacity of the equipment continues to increase, from thousands of bottles per hour to tens of thousands of bottles per hour at present. The operation has also evolved from the manual button type of the past to the current complete computer control, which greatly reduces the difficulty of process operation and increases the stability of the process.
PET bottle blowing process. The important factors affecting the PET bottle blowing process are the preforming parts heating preblowing molds and the environment.
In the preparation of blow molded bottles, PET slices are first injected into preformed billets, which requires that the proportion of secondary recovered material should not be too high (less than 5%), the number of recoveries should not exceed 2 and the molecular weight and viscosity should not be too low (molecular weight 31,000-50000, intrinsic viscosity 0.78-0.85cm3/g). Injection molded preforms can be stored for 48 hours or more. Preformed billets that are not used up after heating must be stored for another 48 hours before being reheated. Prefabricated parts should not be stored for more than six months. The quality of the prefabricated rod is largely determined by the quality of the PET material. Materials that are easy to expand can be selected and a reasonable preforming molding process can be established.Overall, PET bottle blowing is a highly effective and popular method of bottle production due to its low cost, high efficiency, and versatility. It has revolutionized the way products are packaged and has become a staple in the consumer goods industry. Despite some challenges, PET is a safe and environmentally friendly material that will continue to be used for years to come.
