PBBT-2 PET Bottle Burst Tester

Equipment for Control of Resistance to Expand and Explosion of PET Bottle


For PET bottles - Simulating filling process

PBBT-2 PET Bottle Burst Tester is a specialized test equipment for testing the internal pressure resistance of 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 pressureor 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 displaysthe 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.

Mode 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 0.7 bar/s (speed is settable) until the outbreak of the bottle or reaching the max pressure or volume. Preset parameter includes: initial screening pressure, Hold time and ramp speed.

Burst mode

Under this mode, PET bottle will be pressurized rapidly to the initially preset pressure and maintained for a predefined period. Preset parameter includes: initial pressure, Hold time and Expansion limit.

Custom mode

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