Handle PET Packaging With Ease Using High Pressure Air Compressors

Most manufacturers opt for polyethylene terephthalate (PET) packaging due to its durability, flexibility, and recyclability. This material can be molded into a range of shapes and are often clear or transparent green in color. Some products with containers made from PET are sodas, water, liquid hand soap, and pharmaceuticals.

How PET High Pressure Air Compressors Work

High pressure air compressors are used in applications that need consistently high pressure and additional pounds per square inch (psi) to complete specific tasks. This includes PET processing, which involves bottle blowing and the utilization of a conveyor belt. To maintain these machines, you must use proper lubricants and conduct regular inspections.

High pressure air compressors use ambient air and take this gas through various stages of compression to achieve levels of up to 6,000 psi. In these systems, the air is cooled as it moves through each stage to allow for optimal amounts of pressure.

You can also get add-ons called booster systems, which require standard pressure services and inlets of at least 125 psi. Having such components allows for discharge pressure ranges of 450 to 640 psi. They are also built for specific points of use since these devices use pre-compressed air from existing systems.

Bottle Blowing and Molding Using PET High Pressure Air Compressors

You can use high pressure air compressors in bottle blowing and molding, which involves the following steps:

Preform Injection

PET bottle production often begins with preform injection. In this step, the resin is melted and injected into a mold cavity to create a preform, which is a small, tubular-shaped piece with a neck finish. PET high pressure air compressors provide the necessary compressed air for molding the preforms with precision and consistency.

Preform Conditioning

After injection, the preforms are cooled and conditioned to achieve the desired molecular orientation. High pressure air compressors continue to support this process by providing cooling air and ensuring uniform temperature distribution. This is crucial for producing high-quality bottles with the desired mechanical properties.

Stretch Blow Molding

The final step is stretch blow molding, where the preforms are reheated and stretched in a mold to take on the desired bottle shape. PET high pressure air compressors are again utilized to provide the necessary air pressure to expand and shape the preforms into their final form, ensuring that the bottles are durable.
