Reusable  Plastic Water Bottle Manufacturing 

Materials and Equipment Needed:

1. Plastic resin pellets: Our selection of plastic materials includes PP, PC, Tritan, SK, PETG, PS and AS. All of our materials are 100% BPA-free and meet food-safe grade standards.we are dedicated to supplying BPA free water bottles for a healthy life.

2. Inject molding machine: This machine is used to mold the bottle's shape.

3. Mold for bottle design: The mold determines the bottle's shape and size.

4. Blow molding machine: Used for stretch-blow molding to create the final bottle shape.

5. Preform heating equipment: To heat the preforms for stretching.

6. Cooling system: To cool and solidify the bottles.

7. Labeling and packaging equipment.

 

The Manufacturing Process Followed as Below:

1. Preparation of material :

Plastic resin pellets are melted and injected into a mold to create the "preform." The preform is a smaller, thicker version of the final bottle's shape.

2. Preform Heating:

The preform is heated to a specific targeted  temperature, making it pliable for stretching without losing its shape.

3. Stretch-Blowing Molding:

The preform is put into a blow molding machine, which stretches and blow it up  with compressed air. This processing shapes the preform to the bottle's final figure.

4. Cooling down:

The hot bottle is quickly cooled down to retain its shape. This is finished with  a cooling system.

5. Quality Check:

Bottles are inspected for defects and quality issues, and any defective bottles are removed from the production line.

6. Labeling and Packaging:

Labels are sticked to the bottles, and they are packaged for distribution.
