Use the cost of producing preforms to produce bottles

AOKI's Injection Stretch Forming Machine utilizes a direct temperature control method to simultaneously preform and preform PET raw materials, producing high-quality products with minimal energy consumption, and providing maximum advantages in reducing logistics costs and container manufacturing costs. The “direct temperature adjustment method” means that the high-precision, high-strength, thin-wall temperature adjustment process of the left and right products is completed at the same time as the preform molding. Therefore, no reheating process is required from the raw material to the container, and the forming is performed at three stations. Process: preform injection molding temperature regulation - extension - blow molding - product ejection.

The injection rate increased by 25% to achieve thin-walled preform molding, even if the 1.9mm thick preform can be stable. Using this technology, AOKI has developed a variety of ultra-thin and ultra-light PET bottles: 11g/750ml; 14g/1000ml; 16g/1500ml. These bottles, named "Ugly Duckling", look like they are weak and actually have very high strength. In addition, it also has many advantages: As the bottle can be squeezed, the liquid can be squeezed to near the bottle mouth after the inner liquid, such as edible oil, is used, and the oxygen can be emptied and then screwed on the bottle cap to avoid deterioration of the edible oil. In addition, it can be squeezed to reduce the occupied space and so on.
