The AT2E Stress Crack Tester is designed to test the internal stress in bottle base and for determining the stress crack resistance 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.
Attributes:
- Muilt-position design, more convenient and efficient (Please consult AT2E for other position reqeust)
- PLC control ensures the high accuracy and reliability
- High quality stainless steel frame, more safe and duable
- Flexible position selection, each position can be controlled separately by system. Users can enable the positionsaccording to their test reqeust
- Automatic affusion system
- Auto pressure compensation during test process
- Suitable for testing various bottle size
- Corrosion-resistant design
- Anti-explosion and clear observation window, safe and easy to observe the sample status during tests
- Various safety design
Technical data:
- Testing pressure: selectable from 0 – 6 Bar (Please consult AT2E for higher pressure request)

- Communication port: RS232
- Air supply: 0-8 Bar (Air supply ≥Max. testing pressure)
- Water supply: tap water (≥ 1.5 bar)
- Main supply: 220 V
- Overall size: 190×66×123 cm

- Mini printer
- 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
