SCT-D Stress Crack Tester (26 Positions) 

For testing the Stress Crack Resistance of Carbonated Soft Drink Bottles

The AT2E SCT-D 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.

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

Or, the operator can press the position button to stop pressurizing if any tiny leakage occurs by observation. 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, a position with a green light will be displayed as “NG” with the leakage pressure value. The normal position will be displayed as “OK” with the predefined pressure value. The data table can also be printed out through the mini printer.
