Working Principle of Custom Blow Molding Mold

The operation of a custom blow molding mold is integrated into the blow molding process.

Process Steps

1. Preform Heating
   Plastic preforms are heated to a suitable temperature

2. Mold Closing
   The mold closes tightly around the preform

3. Stretching Process (for PET)
   A stretch rod elongates the material

4. High Pressure Air Blowing
   Compressed air expands the preform into the mold cavity

5. Cooling and Solidification
   Cooling channels remove heat efficiently

6. Bottle Ejection
   Finished bottles are released
