To make a PET (polyethylene terephthalate) plastic water bottle, the following steps are typically followed:

  1. Raw materials preparation: PET polymer, colorants, and other additives are combined in a hopper and fed into a dryer to remove any moisture.

  2. Extrusion: The dry polymer is fed into an extruder, where it is melted and shaped into a continuous plastic sheet or parison.

  3. Blowing: The parison is then transferred to a blow molding machine, where it is placed in a mold and inflated with air to take the shape of the mold.

  4. Cooling and trimming: Once the bottle has been blown to the desired shape, it is cooled and trimmed to remove any excess plastic.

  5. Inspection and packing: The finished bottles are then inspected for defects and packaged for distribution.

It's important to note that the specific process for making PET bottles may vary depending on the manufacturer and the specific equipment being used.
