Plant engineers and quality departments often struggle with zero point drift during air leak testing, where the initial zero reading shifts over time, leading to frequent adjustments of the leak test instrument. This article addresses the causes of zero drift, commonly attributed to changes in shop floor temperature, and provides strategies to minimize or eliminate this issue for improved efficiency in quality control processes.
Some manufacturers will use a single-point calibration system to measure volumetric flow—however, a two-point calibration provides a much higher level of accuracy.
Manufacturers that routinely challenge their leak tightness testing process will consistently produce products with reliable performance, battery longevity and safety.
Your choice of leak test method and technology can make a substantial difference in the results of your test, affecting your throughput, repeatability, product quality, and cost.
Leak testing, which has always been essential in the automotive industry for ensuring the manufacture of quality parts and components, is taking on added importance in the mobility age.
Leak testing helps manufacturers boost quality without unnecessary costs. It enables them to improve their production process, ensuring efficient assembly and minimizes scrap, delays, and cycle times.
Times change, technologies change, but the fundamentals of leak testing remain the same – the reliability and repeatability of your test results depend on how well you understand and compensate for testing variables.
EV battery cells, battery packs, electric motors and other systems modified for EV applications all require leak testing to assure both quality and safety.
The rapid and unexpected growth in the production of alternative drive systems is presenting automakers and their suppliers with a host of leak-detection challenges to ensure vehicle safety and quality.
Automakers in Europe, the Asia-Pacific region and the United States are struggling with performance and safety issues associated with electric and hybrid-electric cars.
Helium is in short supply and its cost is rising. Global sources may even run dry by the end of the century. And yet, it remains the dominant choice for trace-gas-based leak-testing on the production line. How can you make the most of this increasingly precious commodity for your critical quality assurance needs?
