Coke bottle production revealed

 

Do you know about that bottle of iced cola in your hand? It didn't just appear out of nowhere! Today, we'll take you inside Baojie to uncover the journey of a cola bottle's birth!

PET

Injection Molding Machine, the "Creator" Behind the Bottles

Imagine a huge machine, as if it possesses magic, capable of turning plastic pellets into various shapes. This is the PET injection molding machine, the core equipment for producing cola bottles!

Production Process Unveiled:

  1. Particle transformation: Plastic particles are fed into the injection molding machine, where they melt at high temperatures and turn into a viscous liquid. This liquid is then injected into a mold by the injection molding machine. The mold, much like a "template" for a cola bottle, determines the shape and size of the bottle, and then the preform is made.

  2. Mold shaping: The preform, after being heated, is placed into the blow molding machine and blown into the shape of a cola bottle using compressed air.

  3. Cooling and shaping: After cooling, the plastic liquid solidifies into shape, and the prototype of a cola bottle is born!

  4. Quality inspection and packaging: After passing strict quality tests, qualified cola bottles will be packaged and await shipment to the cola factory.
