Buckle & Burst Tester: Aerosol Cans

As material costs continue to rise, companies need to reduce operating costs while maintaining high quality standards. To ensure that every aerosol can produced is within specifications, it is important to use accurate and repeatable measurement instruments that can monitor the product quality, locate any potential problems, record the measurement data and predict future trends.

Analog-based testers are no longer sufficient in today’s competitive environment. These gauges won’t tell you which side of the can buckled first, and they can’t monitor all three pressure points in one run (the two buckling pressures and the burst pressure). If you want to record and analyze the data, you need to write down each measurement and enter the data manually in to an SPC program.

CMC-KUHNKE’s new Aerosol Buckle & Burst Tester is an accurate, user friendly and affordable system that automatically measures, analyzes and records all pressure points on any size aerosol can. The system displays the pressure and volume graphs and allow the operator to see the exact point where the can buckles (dome reversal) and bursts – automatic detection determines the exact point where the top or bottom dome buckle.

The software provides easy to read information on the can and records the data in the built-in Symphony SPC system. There is no operator influence on the measurement process and the pressure test scenario (when to raise pressure, by how much, how long to hold, etc.) is completely programmable.

Raise pressure to a predefined value and hold for preset time, if the can withstands the pressure, the can “passes”
