1) All bottle rates are based on finding a 0.17 mm-0.18 mm ( 7 thou inch) hole. With more time we can find far smaller holes. 2) Maximum bottle speed is influenced by bottle wall thickness, bottle rigidity, volume, shape. Contact us for testing of your sample bottles. 3) Test rates for 4-30L are based on heavier oil and chemical bottles, lightweight water bottles can test up to 50-100% faster than above. *) 6LD_C is powered by a Vacuum Conveyor |

Test Rates
The test rate of a container is governed by the following factors:
Volume. Generally our tester is not affected by volume as much as standard designs on the market. Buy the physics of the universe dictate that the pressure decay through a hole in a bigger bottle just takes longer.
Shape. 2 bottle of the same bottle but different shape can have very different test times.
Rigidity. A rigid bottle does not creep as much when tested and generally, the more rigid the bottle the quicker the test time will be.
Stability. If a bottle travels on the conveyor poorly and sways when the conveyor starts and stops, the conveyor has to run slower with a long acceleration/deceleration time. This costs precious testing time.
Environment. In a temperature controlled production area the temperature and humidity are controlled a tighter tolerance can bet set, than in a tropical or sub tropical climate where the day/night temperature variation can be 20-30 degrees centigrade. The above mentioned video was done in summer on a hot day with a lot of temperature variation in a non-insulated shed.
How small a hole can we find?
The answer to this is how much test time do we have available.
On the 1 litre oil bottle shown in the table on the high speed machine the test time is around 0.45-0.5 seconds, with a pressure drop of around 0.15 Kpa, by 2 seconds the pressure drop is > 0.4 Kpa.
So a hole smaller than 0.05 mm would take around 1.5-2 seconds to create a pressure drop of around 0.1-0.15 kpa which we can easily and consistently check with the typical variation in bottle production.
Thus if you have the time holes smaller than 0.05 mm can be found. In fact given time we have extrapolated that holes down to > 0.02 mm can be found.
