Common Tests: Bursts
Pressure testing until the point of explosion is an effective way to determine the integrity of bottles
Why burst test?
By periodically testing a sampling of bottles from each batch, one can efficiently check for issues in the blowing phase of bottle production.
Parameters than can affect the strength of a PET bottle include the PET resin used, the chosen moulding melt temperature, and the intrinsic viscosity (IV) of the bottle.
The process of filling bottles on a line also exerts pressure, underlining the importance of knowing for certain the quality of the bottles used.
What burst test options are there?
Plastic bottles can be safely burst-tested off the production line with the PBBT-1 Plastic Bottle Burst Tester.
Glass bottles can be tested off-line with the GBBT-1 Glass Bottle Burst Tester.
The fill ramp mode is a commonly used procedure for pressure-testing both bottle materials. Designed to simulate conditions under filling lines, the test involves the following:
For fully-automatic on-line bottle pressure testing, custom options are available.
