Leak Testers

The modular design of Zaxis leak testers enables us to meet the demands of a wide variety of applications.

Leak Testing Critical in EV Manufacturing

Batteries are the most costly and complex part of EV manufacturing. To assure performance and product safety, batteries are leak tested throughout the manufacturing process to meet strenuous specifications.

Zaxis offers solutions for your Automotive Leak Testing Needs. The automotive industry is as demanding as ever with an ever-changing global economy, competition is fierce. Zaxis is here to ensure your automotive components pass the test. Whether you are leak testing...

Leak Testing for IP Standards in the Automotive Industry

Ingress protection is a critical part of product development particularly with the increased use of  electronics in the automotive industry.  Using IP Code is a standardized way to define just how leak proof a product is without using ambiguous terms such as...

Zaxis Occlusion Testing

Occlusion testing checks for blockages in test parts. By measuring the air flow through the test part, a test instrument determines whether the test part is blocked. Different techniques can be used to identify occlusions/blockages in test parts such as air flow occlusion testing, back pressure occlusion testing and pressure drop occlusion testing.

Pressure Decay Test

Pressure Decay Test

What is a Pressure Decay Leak Test?

Pressure decay is one of the most widely used methods of leak testing in manufacturing and is ideal for a sealed component with an access port. In this test, a product is attached to a leak tester and filled with air. Once pressurized, the air source is valved off and the pressure is allowed to settle. During the test any decrease in air pressure over time signifies a leak. If the part does not leak/decay past its predetermined reject value, it is a good part. The sensitivity of this test is dependent upon the product’s size and the time interval of the test. Larger objects require a longer cycle time to reach a high enough sensitivity for a quality test. Smaller objects with small internal volumes will require very low cycle time, allowing a high throughput of production.

Here’s how it works:

  1. Connect your part to a Zaxis leak tester with a fitting or fixture. During the FILL stage your part is pressurized.
  2. Once the desired test pressure specified by the manufacturer has been reached and the fill time has ended, the SETTLE stage commences accommodating for part stretching or flexing.
  3. Once the part has settled and the settle time has ended, the pressure decay TEST initiates. During the test stage a pressure sensor will measure any drop in pressure.
  4. After the pressure decay test the remaining pressure in the system is vented to atmosphere during the VENT stage.
  5. If the pressure decay of your part remains within your specification then your part PASSES and a green light illuminates. If the pressure decay of your part falls below your lower limit, then your part FAILS and the red light illuminates.

The advantage of this type of testing is that it is accurate up to the 5th decimal place or 0.00001 PSI allowing for fast test cycles.

Occlusion Leak Test

Occlusion Leak Test

What is an Occlusion Leak Test?

An occlusion test measures the passage of air through an object and signifies if the object’s passage is clear or occluded/blocked. In this test the product is attached to the test port and filled with regulated air. Once the desired pressure is obtained, all valves are closed off. The air is not allowed to settle and the test begins immediately after the fill stage. During the test, the downstream port is opened to atmosphere and the loss of pressure is measured. If the product exceeds the programed reject value, it is considered a pass. If pressure does not decay past the reject value it is occluded and the product does not pass.

Downstream Occlusion:

For proper operation of this test, a downstream release is required. The iKit, Isaac HD, and Zaxis 7i allow for these release valves to be built in, or you can use a clamp (seal/pinch) valve with any tester to activate an external release.
