Engineering 101 Are you seeing the same regression in the manufacturing engineering field that I am? Some examples are so stunning and confounding—I scratch my head and wonder how it began. Is it poor schooling? A desire for cost-cutting that throws caution and common sense to the winds? Senility? Here’s a case in point that I’ve run across a few times now. Engineering 101 tells us that a leak is measured in standard cubic centimeters per minute, pascal cubic meters per second, milligrams per second, or some ...

Designing a leak-testing system that meets appropriate reliability and reproducibility standards requires a thorough understanding of relevant test methods and technologies. That knowledge base is rarely available in house. Penny wise, pound foolish It is a distressing fact that leak-testing missteps are all too common in the medical device industry. Unlike some industries that traditionally enlist experienced outside applications engineers to develop turnkey test systems, many device manufacturers try to keep this in-house under the misguided notion that they are controlling costs by not outsourcing the project. ...

Cheap Fixtures Cost More in the Long-Run When I travel the world to assist assembly plants that are having difficulties achieving gauge R&R standards, I can usually spot the extent to which testing requirements are misunderstood by taking a quick look at the test fixtures. Off-the-shelf fixtures are a big red flag that immediately suggests that containing upfront costs was the most important driver in designing the system. Everyone wants to minimize costs. That’s understandable with or without a worldwide recession and unprecedented global competition. It’s ironic, ...

Electronic technology for self-calibration and automatic validation M1075Y – Single Channel Leak Detector InterTech Development Company announces that CalVal™, the world’s only electronic technology for self-calibration and automatic validation of leak testing can now achieve an accuracy of +/-2% of reading or 0.02 sccm (standard cubic centimeters per minute). This new CalVal standard further differentiates InterTech’s patented technology for electronic calibration from relatively unreliable mechanical calibration methods and allows manufacturers to maintain the highest quality standards without slowing production line output for time-consuming mechanical calibration. With CalVal, ...

Temperature Compensation What is adiabatic heating or cooling in leak testing applications and why is it significant? During leak testing, when a part is at atmospheric pressure and ambient temperature is pressurized, the incoming air compresses the residual air in the part causing that air to heat. The resulting air temperature, which is now warmer than the part being leak tested, cools to the temperature of the part. This is usually the dominant thermal effect in the leak test. When a part is at atmosphere and then ...
