The production process of PET plastic bottles typically includes the following main steps:

Raw Material Preparation: Select appropriate polyethylene granules as the raw material and ensure that their quality meets the required standards.

2. Injection or Extrusion: After heating polyethylene granules to melt them, the molten plastic is extruded through an injection molding machine or an extruder to form preforms.

3. Pre-form Molding: The pre-form is molded into the mold, forming a bottle with an initial shape.

4. Cooling and Shaping: After molding, the bottles are cooled in the cooling system to set their shape.

5. Trim and Neaten: Trim and neaten the bottles by removing excess parts to ensure a clean and tidy appearance.

6. Quality Inspection: Conduct various quality checks, including appearance, dimensions, and sealing, to ensure product quality.

Packaging and Shipment: Qualified PE plastic bottles are being packaged for shipment.
