PET bottle production involves a stretch blow-molding process, by which a test-tube-shaped preform is made by injection molding and then heated, stretched and filled with compressed air to fill the mold and form the bottle. This process provides the enhanced physical clarity and gas-containing properties commonly required for soft drink bottles.

Erroradially on a wheel as it leaves the extruder. Once inside the mold, air pressure blows the parison into the bottle shape of the mold. The mold is rapidly cooled and removed, producing a bottle. <span>PET bottle production involves a stretch blow-molding process, by which a test-tube-shaped preform is made by injection molding and then heated, stretched and filled with compressed air to fill the mold and form the bottle.

Major companies continue to develop new ways of manufacturing bottles to increase automation and efficiency, reduce material per unit and streamline processes. New proprietary technolog Summary
