Leak testing is a quality assurance process notorious for reliability and repeatability challenges. Steve White discusses how and why Sciemetric includes a self-test function as part of its 3520 Leak Test System, to quickly diagnose any issues that may compromise reliability.
Ron Pawulski explores how poor control of test pressure is one of the most common causes of repeatability issues with leak testing. The answer? Digital smart sensors and software that constantly monitor and adjust to compensate for any variations.
Collecting data isn’t the same as making effective and timely use of the data. Rob Plumridge discusses how manufacturers must invest in robust data management and analytics tools if they expect to achieve measurable gains in production quality and output.
Ron Pawulski offers a checklist of what to consider when choosing a leak test system – your acceptable level of Gage R&R (repeatability and reproducibility), the required test cycle time for your line, and the need for traceability and root cause analysis.
When you’re in the market for a new leak test system, it’s a purchase decision that could be worth hundreds of thousands, even millions, of dollars to your plant. Rob Plumridge discusses the best approach to ensure a wise choice … and your job security.
Joe Ventimiglio discusses how SPC (statistical process control) remains an effective means for manufacturers to spot production problems, but for effective quality management and to quickly trace root cause, you need more – digital process signature analysis.
Even the tiniest air bubbles can ruin the integrity of a seal or adhesive and vision systems alone can’t spot trapped air. Aaron Alberts talks about how Sciemetric teamed with Graco to create a new data-driven quality assurance system for dispense to capture what a camera can’t.
One of the most common questions about leak testing is understanding when to use pressure decay versus flow. We discuss how these two types of test differ and the instances where one is preferable to the other.
Question: Dear John, I’m having a hard time finding the right limits for our test systems. Right now we keep adjusting them, trying to find what works best through trial and error. Is there a way to quickly find the optimal limit settings to get the highest output without affecti…
Question: Dear John, What’s the difference between a pressure decay leak test and a flow-based leak test? How do I know which one I should use? Answer: Leak testing is one of those things that is more complicated than it seems on the surface. The differences b…
