Sealing test tutorial: steps to ensure the sealing performance of equipment - Hai Ruisi takes you to play with the "magic" of sealing

Imagine your device is like a loyal knight, wearing strong armor and guarding the secrets inside.But if there is even a small crack in the armor, "invaders" such as wind, sand and moisture will take advantage of it and cause your equipment to "die prematurely".Data shows that the global failure rate of electronic equipment due to sealing problems is as high as 15% every year, which means that one in every seven devices may be silently "crying".Don't panic!Today, Hirays will take you into the world of sealing testing, using simple and practical steps to ensure that your equipment is impregnable.The following content not only contains useful information, but also a little humor. How about following us to make the most of the sealing performance?

Why tightness testing is more important than you think?

Have you ever wondered why mobile phone manufacturers always brag about "IP68 waterproof and dustproof"?Because sealing is the lifeblood of equipment!It determines whether your device can calmly take a selfie in a rainstorm, or give you a "cardiac arrest" in the shower.Tightness testing is not a nice-to-have, but a life-saver.For example, Xiao Ming’s drone flew on the street for two minutes in the rain. Why?The sealing gasket is aging, the test has not kept up, and the moisture directly invades the circuit board.On the other hand, Xiaohong’s Hai Ruisi sealing test equipment undergoes strict testing before leaving the factory every time, and can still “dance” in the wild wind and rain outdoors.Poor sealing is like opening a back door to the equipment, and anyone can come in and cause trouble.Have you ever encountered the embarrassment of equipment breaking down "inexplicably"?Leave us a message and let us know!

Not to mention the rigid requirements in the industry, such as medical equipment and automotive sensors. If the sealing is not up to standard, it may not be a matter of money, but a matter of human life.Engineers from Hirays have seen a case in which the sensor seal of a certain brand of car was not properly sealed, moisture penetrated, and the brake system failed, almost causing a catastrophe.So, don’t underestimate this little test, it is the first talisman for the “longevity” of your device.

Before the sealing test, you must first understand these "foreplays"

Don't rush into testing, check if your device is "ready" first.It's like taking a shower and changing clothes before going on a date. You can't just show up looking sloppy, right?The first step is to check the seals - small things such as rubber rings and gaskets. They are the "main force" of waterproofing.Once our team was testing an industrial controller and found a crack on the rubber ring that was invisible to the naked eye. What was the result?When the water pressure increased during the test, it leaked like a fountain.So don’t bother, grab a magnifying glass and take a look to make sure these little guys are in perfect condition.

The second step is to understand the "temper" of the device.Different equipment has very different sealing requirements.For example, Hai Ruisi's outdoor cameras have to withstand strong winds and heavy rains, while home speakers may only need to protect against kitchen moisture.You have to know where the "battlefield" of your equipment is so you can be targeted.Don't forget to clean the contact surface. "Invisible killers" such as oil and dust will greatly reduce the sealing effect.Just like you have to wipe the mold clean before making a cake, otherwise who would want to eat the cake if it's burnt?By doing these "foreplays" in advance, you can get twice the result with half the effort during the test.

The "hard core" steps of sealing test: teach you step by step

Okay, here comes the main event!The sealing test is actually not that mysterious. Follow the steps of Hai Ruisi and you can become a "sealing master".Choose the right testing method.Common ones include air tightness test and water immersion test.The air tightness test is like blowing up a balloon to the device to see if it can "hold the air"; the water immersion test is just throwing it into the water to see if it can "drink the water".We have a customer who used Hai Ruisi's air tightness tester to test the mobile phone case, and the air leakage point was found in 3 seconds, which was so efficient that it seemed like it was leaking.

Next, set up the test conditions.Parameters such as pressure and time must be adjusted according to the needs of the equipment. Don't try blindly.For example, when testing a diving watch, the water pressure must simulate a water depth of 30 meters, otherwise the test will be in vain.Don't forget to record the data.What is the air leakage rate?What's missing?These are all "evidence" to help you find the root of the problem.Hai Ruisi's equipment comes with built-in data analysis functions, which saves you from having to make dizzy calculations manually.Which testing method have you tried?What's the effect?Let’s talk about your experience!

Guide to avoid pitfalls: 90% of people have made these mistakes

The sealing test sounds simple, but there are many pitfalls.For example, some people think "it's almost enough", but as a result, a large number of equipment are returned for repair after leaving the factory, and the money spent is enough to buy ten testers.There are also people who ignore environmental factors. In summer, the test is fine, but in winter, it shrinks and leaks overnight, and it is too late to cry.A customer of Hai Ruisi suffered this loss. The temperature difference was not considered during the test. As a result, the product was "stopped" when it arrived in the north.So, don’t be lazy, the test conditions must be as close to the real scene as possible.

There is another big pitfall - neglecting regular re-inspections.Seals age, just like human skin develops wrinkles, and their performance degrades over time.Don't think that everything will be fine after just one test. Make a plan and review it every six months to nip problems in the bud.Think about it, would you rather spend hundreds of dollars repairing the equipment, or spend a few minutes testing it?The answer is obvious.Students who have stepped into pitfalls are welcome to leave a message to share your "history of blood and tears", and we can learn from each other together!

Practical Advice on Leakage Testing: Keeping Your Devices Long-lasting

After reading the previous content, do you think the sealing test is not that difficult?Next, Hai Ruisi will give you some very practical suggestions, please save them now:

1. Choose reliable sealing materials: Don’t be greedy for cheap and buy low-quality rubber rings. Good materials are like putting on brand-name body armor for equipment.Just like Xiao Wang chose the silicone pad recommended by Hirays, the life of the equipment was literally extended by two years.
2. Do your homework before taking the test: Checking seals and cleaning surfaces is just like reviewing key points before taking an exam. The more prepared you are, the more likely you are to win.
3. Save worry with professional tools: Hiraysi’s air tightness tester is 10 times faster than manual testing. It’s like installing a smart oven in the kitchen, so you don’t have to worry about cooking.
4. Don’t be lazy with regular re-examination.: Once every six months, it’s like maintaining a car, a small investment can lead to greater peace of mind.
5. Record data to find problems: Keep a "diary" for each test. The next time you improve, it's like playing the game according to the guide and passing the level easily.

Conclusion: No worries about sealing, and a promising future

The sealing test, to put it bluntly, is to add a "protective umbrella" to the device so that it can hold its head high even in wind and rain.Haris hopes to pass
