Product Description

Stress Crack Tester

The AT2E Stress Crack Tester is designed to test the internal stress in bottle base and for determining the stress crackresistance of blow-molded PET carbonated soft drink bottles by measuring the propensity for base cracking upon exposure to an aqueous sodium hydroxide solution under a controlled environment, so that to estimate the long term behavior of bottles.
Testing procedure:
- Install and clamp the sample bottle on each position then close the door
- Affusion head will seal and fill the bottle automatically with target volume of water then pressurize the bottle to predefined pressure and stay for a target time (like 5 minutes). At same time of water filling and pressurizing, system will fill the solution into each posistion
- After target staying time is up, all the testing positions descend until the predefined distance and bottle base will be coverred by the solution completely
- Record the time and pressure for each bottle to failure until predefined time
- Test stops after the predefined time

  1. Muilt-position design, more convenient and efficient
  2. PLC control ensures the high accuracy and reliability
  3. High quality stainless steel frame, more safe and duable
  4. Flexible position selection, each position can be controlled separately by system. Users can enable the positionsaccording to their test reqeust
  5. Automatic affusion system
  6. Auto pressure compensation during test process
  7. Suitable for testing various bottle size
  8. Corrosion-resistant design
  9. Anti-explosion and clear observation window, safe and easy to observe the sample status during tests
  10. Various safety design
