• Requires manual preform loading and bottle removal

• Automates critical steps such as heating, stretching, and blowing

Key Characteristics

3. Working Principle

The DR-25 operates based on two-step stretch blow molding, ensuring high-quality bottle production for large-scale containers.

Step-by-Step Process

1. Preform Preparation
   PET preforms are produced using injection molding systems.

2. Infrared Heating
   Preforms are heated evenly to optimal forming temperature for PET.

3. Manual Loading
   Operators place preforms into mold cavities.

4. Stretching
   Stretch rods elongate the preforms to align polymer chains, increasing mechanical strength.

5. High-Pressure Air Blowing
   Compressed air expands the preforms into the mold shape.

6. Cooling Phase
   Bottles are cooled within molds to maintain shape and structural integrity.

7. Bottle Ejection
   Finished bottles are removed manually or semi-automatically.
