Leak testing systems for quality control of products and assemblies

Liquids, dust, or air – component leaks usually lead to errors in downstream processes or product defects at the end customer. To avoid these scenarios and the resulting follow-up costs, it is necessary to test products for proper tightness.

With our AUTFORCE CUBES, we support you in the quality control of your components. Together with our partner ATEQ, the leading manufacturer of industrial leak testers, we combine the specialized knowledge of two industries to make your day-to-day production even more efficient. Inline or stand-alone, with manual or automatic loading – we adapt to your needs!

Possible tests

Measurement via

Differential pressure

A differential pressure sensor (4) is used to determine the pressure difference between the test object (5) and the reference (3).

  5. DUT (device under test)

Measurement via

Relative pressure

For this test method, the test pressure is applied to the input
of the test part (3).
The pressure drop is measured via the pressure sensor (2).

  3. DUT (device under test)

Measurement via

Flow rate

A differential pressure sensor (3) measures the pressure drop across the laminar flow element (2). The pressure of the test specimen (5) is measured by the test pressure sensor (4). The flow rate in the system can thus be calculated.

Measurement via

flow leakage

The internal tank (6) is pre-filled with the test pressure as soon as the test item (5) is connected. In case of leakage, the leakage flow passes through the calibrated flow element (2). A pressure drop occurs and is measured by a differential pressure sensor (3). The pressure of the test specimen (5) is measured by the test pressure sensor (4).

Fields of application

Our leak test stations can be used for a wide variety of activities:

  • Incoming goods inspection
  • Inline quality monitoring
  • Pre-series & small batches (ramp up)
  • End-of-Line Inspections
  • Prototype inspection
  • Return check
  • After Sales (spare parts manufacturing)

Your advantages

Flexibility

Inline or stand-alone, with or without IO/NIO component identification. Our leak test stations are individually adapted to your requirements.

Digital component file

Using unique component identification, all test data for the particular component is compiled in a digital file. This ensures complete traceability for the fulfillment of certain standards (automotive, medical technology, aviation, etc.).

High level of automation

A high level of automation is achieved thanks to automatic contacting of the test object and the possibility of automatic handling. This ensures a consistent, reliable testing process.

Guided processes

Thanks to the visual worker guidance of our autfactory, it is possible to ensure that the individual process steps are followed. In addition, 100% traceability is guaranteed.

Overview of our testing plants:

No matter what the testing task, our burst, gas and leak test benches are individually tailored to the particular requirements:

  • Burst testing stations
  • Helium and trace gas stations
  • Leak and function test

Step 1

Insert the component

The components can be inserted into the leak test station either manually or automatically. Openings to be closed are sealed and the test is performed automatically.

Step 2

Leak test

The components are checked for possible leaks using differential pressure measurement, relative pressure measurement, flow measurement or flow leak measurement. With unique component identification, the test results are recorded in an electronic product file for the component.

Step 3

Eject NIO parts

NIO parts are detected and can be rejected directly. In case of repeated occurrence of defective parts, you can react immediately and optimize upstream production (trend detection). As a result, you reduce scrap and increase your output.

Data tracing with autfactory

In combination with our autfactory shopfloor management system, you also benefit from central control and seamless data tracking of the station. Changes in the test sequence can be made quickly and easily using the visual editor, without any programming knowledge.

Thanks to data tracing down to batch size 1, you ensure the quality standards of your production. With autfactory, we can help you gain valuable insights, identify potential, and thus increase the output of your production.
