For test of internal stress in bottle base.
InquiryThe 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)
2 test modes: “SP” & ”PS” mode. “SP” mode is to auto fill the samples with water and fill the vessels with solution, then lifting units descend to the predefined distance and then pressurize the samples according to the CYCLE setting. “PS” mode is to auto fill the samples with water and fill the vessels with solution, then pressurize the sample first and hold for the preset time, then the lifting units descend to the predefined distance and keep pressuring the sample according to the CYCLE setting
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

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
