Anyone using leak testing instrumentation on production lines for inspecting components or assemblies for leaks and/or flow rates can now achieve both higher quality and efficiency operations through improved training offered at no-charge by Uson.
Our hands-on leak testing training sessions are held in various Uson worldwide locations and in
Uson Model 628 Leak Tester
This month I am going to introduce you to the model 628 leak tester, but first a little background to set the stage.
Pressure decay leak testers have long been the mainstay of leak detection in the automotive, medical device and general industrial products
Leak testing has come a long way since 1963 when Uson was founded, and like most new industries the rate of innovation was fast at first. New and improved leak testers were regularly being introduced as more and more applications arose for our products and technology. Although we continue to
Anyone reading this who is involved in the leak testing of flexible packages will be familiar with the methylene blue dye leak test. For years it has been the go to test for detecting leaks in flexible packaging – foil or laminate pouches, bags, blister packs, lidded trays, flow wrap
When it comes to NDT testing of various kinds, the types of components that you use to create the test circuits always have impact on the capability of your testing solution.
For example, in leak testing, choosing the right-sized valves and sensors for your test equipment can make or break
“We are what we repeatedly
not an act but a habit.”
I came across this quotation recently and it quickly struck me how it relates to quality assurance. And so, with it being the beginning of a new year, this post is rather more
“Uh-Oh, what could this possibly be about?” you might be wondering. There can’t be any such thing as “zero-time”.
Well, strictly speaking you are right, but there’s a neglected feature in the Optima leak tester that we couldn’t think of a better name for.
The Uson Optima vT is designed
In this post I thought we might try to put hole sizes,leaks, and leak rates in perspective.
Much continues to be written about determining realistic leak specifications and the chestnut of the “no leakage permitted” type of specification is still commonly encountered.
Looking through some old training material I thought
I think I have said this before; medical devices can present some of the greatest challenges in leak testing. That’s kind of ironic in a way, since they are often among the smallest things we are asked to test.
The sheer variety is mind boggling. You can easily be forgiven for wondering where they all go with a visit to just one manufacturer.
Because they perform vital often life saving functions, it’s no surprise that testing them correctly is vital. If even one bad part reaches a patient the consequences can be catastrophic. This leads us to the first challenge:-
One hundred percent inspection
In some industries although the quality engineer seeks perfection there can exist a compromise between inspection and throughput by using statistical sampling methods. In the medical device industry perfection and production objectives must be met without compromise. Therefore fast, one hundred percent inspection is expected and it demands multi channel leak testers as well as accurate and reliable fixturing.
Everybody knows that medical device manufacturing is a highly regulated industry. It’s for the safety and peace of mind of patients, not just in the USA, but around the world. No one would argue that’s not a good thing. However, it brings with it ever increasing requirements for capturing and storing data. Some devices are serial numbered, chipped, or bar-coded and that brings us to the next challenge:
