For PET bottles – Simulating filling process

PBBT-2 PET Bottle Burst Tester is specialized test equipment for testing the PET bottles. It’s designed in accordance with the three international test methods which are commonly used. Users can choose the test method basing on their requirement. The PBBT-2 is capable to test the capacity of resilience under certain pressure or the rupture test of the PET bottle.

Through the reproduction of the pressurization, the process has been linearized and it increases to the predetermined point or the point of bursting.

After selecting the test program, the cycle will start automatically depending on the settings. The touch screen displays the pressure value in real time and record the maximum pressure and burst pressure.

Optional part water recycling system could provide way of saving water and avoiding the unsteady pressure of tap water which may influence a normal test.

Additional booster could be chosen. It may help the PBBT-2 free of high pressure source.

Modes details:

Fill ramp mode:

The filling ramp mode is designed to simulate the situation of filling lines of PET bottles. Under this mode, the PET bottles are pressurized rapidly to the initially preset pressure and maintained for a given time (for example 13 seconds). Then continue to increase the pressure with a speed of 0.1 bar/s until the outbreak of the bottle or reaching the max pressure or volume. Preset parameter includes: initial screening pressure, maximum pressure, and expansion of volume limit.

Burst mode:

Under this mode, PET bottle will be pressurized rapidly to the initially preset pressure and maintained for a predefined period.

Custom mode:

Under this mode, user is able to create the pressure curve to meet the particular conditions of control. Users can define the pressure curve by steps, after the adjustment is made, the corresponding curve will be displayed on the user interface.
