CETA tester-based differential pressure leak testing



CETA tester-based differential pressure leak testing

Leak testing is a common post-machining step stipulated on technical prints for aluminium castings. We first met this type of specification when machining a double housing for a Bosch electric traction motor, which was designed for applications in electric vehicles.

The electric motor housing through which coolant flows must be sealed, so microporosity is simply unacceptable in this application. A fully automatic leak tester is used for this precise purpose – to detect leaks. The device works on the principle of comparing the pressure in a given volume of the component under test and the pressure in a sealed reference volume. Maximum deviation is 0.02 Pa. The measured values are processed in real time. Testing one cavity takes a couple of minutes. Every test includes a device that enables the enclosure of the volume under test in addition to the tester itself.

3D measurement

The Technical Control department, led by the Quality Manager, defines the measurement plans, documentation for initial sampling, or the entire set of documents required for specific requests. Typical requirements include 3D measurement equipment reports and the traceability of production and measurement data.

CNC machining

The perfect assessment and alignment of a specific volume of technical information is the secret to the automated manufacturing of flawless components. Suitable technical equipment with the necessary parameters is the primary prerequisite.
