For testing the stress crack resistance of multiple carbonated soft drink bottles
The AT2E SCT-D Stress Crack Tester is designed to test the internal stress in a bottle’s 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 in a controlled environment, the user can simulate the long-term behavior of bottles.

Models available:

  • 6 testing positions
  • 12 testing positions
  • 26 testing positions
As per the above screenshot, during the test the bottles in the #6 and #16 positions leak, the lights of positions #6 and #16 will become green automatically, and system will stop pressurizing the corresponding positions.

Alternatively, the operator can press the position button to stop pressurizing at any point. Leak pressure value and time will be displayed below the button.

The system will also generate a data table for each test to record the test pressure of each position. In the table, positions with a green light will be displayed as “NG” with their respective leakage pressure value. A normal position will be displayed as “OK” with the predefined pressure value. The data table can also be printed out through the mini printer.

Attributes:

  • Multi-position design, more convenient and efficient (Please consult AT2E for other position request).
  • Automation control ensures high accuracy and repeatability.
  • High quality stainless steel frame, which is safe and durable.
  • Superior control components ensures accuracy and durability.
  • Flexible position selection – each position can be controlled separately by the system. Users can enable the positions (from 1 to 26) according to their testing requirements.
  • Automatic pressure compensation during the test process.
  • Suitable for testing various sizes of bottle.
  • Corrosion-resistant design
  • Anti-explosion and clear observation window, which allows a safe and easy way of observing sample status during a test.
  • Various safety features.

  • 10” LCD touchscreen display
  • Recommended solution: Sodium Hydroxide (NaOH) Solution  0.200%
  • Recommended operating temperature: 5 – 50 °C
  • Communication port: RS232
  • Air supply: 5-8 Bar (Air supply ≥Max. testing pressure)
  • Power supply: 220 V
  • Overall size:  168 x 74 x 85 cm
  • Net weight: 250 kg

Optional parts:

  • Mini printer
  • Software
