We’ve written before about what to consider when choosing a leak test system. Today, we’re adding another element to this discussion – internal diagnostics. In the previous post, we talked about three considerations when choosing a leak tester: your desired gage R&R (repeatability and reproducibility), the cycle time required for the leak test to keep...

In a follow-up to our “How to conduct a leak test trial you can stake your job on” post, the topic today is one of the most overlooked causes of poor repeatability in leak test results. Achieving leak rate repeatability is a common challenge with leak testing. Changes in test results can cause a customer to mistrust their leak test and even lead an operator...

Manufacturers are increasingly aware of the need to have long-term accountability to their customers and stakeholders – “we built a good part and have the data record to prove it.” With waveform signature analysis, they have the data trail they need to quickly find the root cause of a problem, determine its scope, and carry out a targeted recall of only the...

Let me tell you a story:There was once a manufacturer of off-highway equipment, a premium brand with a strong reputation in the market for reliability and prompt customer service. But they were having a problem – leaks in the transmissions for one of its flagship vehicles. This was leading to a lot of warranty claims and returns that were proving costly and...

When you’re in the market for a new leak test system, it’s a purchase decision that could be worth hundreds of thousands/millions of dollars to your plant. That means your job could rest on the choice you and or your team makes.The best approach is to pit your top vendors against each other in a head-to-head trial. But first, you need to step back and...

There is defect on your line you just can’t catch. Maybe it’s showing up in a first-time yield rate that refuses to improve, or in the number of warranty repairs that are coming in. No matter what your people do, it just can’t be pinned down. They blame it on the limitations of your quality assurance process. That leaves you wondering if the hardware and...

Products are failing on your production line. Productivity is suffering as yields drop and the cost of scrap and rework climbs. You’re relatively confident that all the faulty units are being caught, but because your quality assurance process relies on a simple pass fail based on single data points like “max force” or “max leak rate,” you have no way of...

From auto parts to running shoes, manufacturers constantly battle one chronic quality issue when it comes to adhesive and sealant dispensing on a production line. Even the tiniest air bubbles can ruin the integrity of a seal or adhesive. On a car wind-shield, engine or medical device, a poor seal can put consumer safety at risk and lead to high cost...

Finding the right limits for your in-process tests is crucial to achieve the highest production yields and minimize, as much as possible, the risks of defective parts slipping through.Manufacturers have long had access to the smart tools they need to quickly optimize their test limits. And yet, many still rely on archaic methods of trial and error, wading...

One of the most common questions about leak testing is understanding when to use pressure decay versus flow. First, let’s take a look at how each test works. In pressure decay, the part under test is pressurized (i.e. filled with air until it reaches a set pressure), then isolated from the supply pressure. The pressure within the part is then monitored...
