Key Definitions

3. Working Principle

The DR-2000-2 operates using a two-stage stretch blow molding process, which provides high precision and uniformity for wide-mouth containers.

Step-by-Step Production Workflow

1. Preform Feeding
   Preforms are automatically loaded into the feeding system. The system accommodates both standard and wide-neck preforms.

2. Infrared Heating
   Preforms are heated to a specific temperature profile to ensure optimal molecular orientation and stretchability.

3. Stretching Stage
   Stretch rods extend the preforms vertically, improving material distribution and container strength.

4. High-Pressure Blowing
   Compressed air inflates the preform into molds, forming the container’s final shape and size.

5. Cooling Phase
   Molds cool the container uniformly to prevent warping and ensure dimensional stability.

6. Automatic Ejection
   Finished containers are discharged, ready for downstream processing. Operators may intervene for quality checks or small-batch adjustments.
