Respuestas a la pregunta
Explicación:
Step 1:
PET is made by combining a colorless, odorless organic compound called ethylene glycol with terephthalic acid.
Step 2:
PET resin is melted to create a test-tube-like shape, designed with the ability to take on any shape or thickness. The opening of the neck of the bottle is already present in its final form and receives the cap at the end of the manufacturing process. This tube is called a pre-form, it is the first figure and it is produced by a high speed process called injection moulding.
Step 3:
Each preform is heated in an oven at a temperature of around 100°C. Heating softens the preform and makes it elastic, allowing it to be stretched and blown into the shape of the mold. All this is done in a blowing machine, equipment that comes in various models to adapt to specific manufacturing needs such as production speed and process.
As soon as the bottle is blown, it should be chilled immediately to ensure that it retains its shape.
Step 4:
The newly created PET bottle is then filled with the beverage.
