What are the Challenges in Automotive Leak Testing?

Posted by:

As the technology for AV & EV vehicles continues to rapidly advance, automotive design engineers are having to re-think automotive design. “Out of the box” thinking – literally and figuratively – is the order of the day if automotive vehicles – trucks, passenger vehicles, buses, taxis and more – no longer must think first and foremost of enabling a human driver to see and navigate the road.

The challenge of leak testing for the automotive industry is geared more towards manufacturing engineers and answering the question of – How can the components used for AV & EV vehicle designs be brought to market quickly and inexpensively?

Some other Updates on Testing Options- – Tackling Costs!!

Isn’t Pressure Decay Leak Testing Always the Lowest-Cost Method???

Answer: No! Pressure Decay Test Methods Can Raise Costs Up to 50%!

Many make the mistake of equating the upfront costs of a leak tester instrument with the costs of the leak testing in total. Over the economic life of a leak tester, the upfront costs of the test instrument are a mere fraction, often trivial, of the overall testing costs.

 Pressure-decay leak testing is difficult because measurements are highly vulnerable to changes in testing conditions such as drafts or temperature and there are often difficulties in determining the volume of test parts and test circuits, which must be known in order to calculate results. Also, pressure decay methods, including differential pressure decay methods, have hidden costs that derive from the need to make two measurements and then correlate results to determine a leak rate. Two measurements mean double the chances for measurement error. In addition, the longer the interval between the two measurements the higher the probability for measurement error – especially for leak testing large volume parts.

The problems inherent in pressure decay can be avoided by using an InterTech M1075 with LeanPass™ to achieve a cycle time reduction of up to 50%.
