--- Both use standard compressed air as the mediumAir tightness testingits future and direction

Since 2015, whether domestic manufacturers are ODM, OEM, or OBM, the sealing performance, waterproof performance, and air tightness testing of the products they produce have been officially put on the quality management agenda.And some leading manufacturers in the industry have taken the lead in implementing a quality mechanism for full online product inspection; realizing the storage and uploading of test results to trace the quality; realizing seal detection,Air tightness testA guarantee mechanism interlocked with other quality inspections.

And this kind of onlineAir tightness testingThe demand for quality control is exploding, and the demand for quality control is becoming more complete and perfect. So, which industries and fields currently use waterproofing and sealing performance testing?

1. The traditional product itself must have waterproof and dustproof requirements.

2. The newly developed various new smart products have also begun to have clearer requirements for waterproof performance.

3. Products whose original functions have been upgraded and have additional requirements for waterproofing, dustproofing and sealing, or whose protection level has been improved, and which previously had no special requirements for waterproofing, dustproofing and sealing performance.

Traditional industry products are already sealed and waterproof. Typical representatives include: outdoor security monitoring equipment and facilities, communication base stations, outdoor communication equipment, various outdoor lamps, valves and pipes, auto parts and motorcycle parts, medical equipment and facilities, water-related items, etc.

Typical representatives of various newly developed smart products include: bracelets, smart watches, outdoor sports speakers, auto parts (car cameras, antennas, etc.), small smart home appliances (electric toothbrushes, facial cleansers, face brushes, etc.).The reason why everyone attaches so much importance to sealing performance, waterproof performance and air tightness testing, the editor believes that the reasons are as follows: Although it is not necessarily comprehensive, it must be representative.

Typical representatives of product function upgrades include: smartphones, sports speakers, Bluetooth headsets, diving watches, diving cameras, electric toothbrushes, motors, electric shavers, waterproof sockets, etc.

The reason why everyone attaches so much importance to sealing performance and air tightness testing, the editor believes that the reasons are as follows: not necessarily comprehensive, but representative to a certain extent.

1. Quality determines the market!Only when the quality and waterproof performance of similar products are superior to those of its peers can they be stable and far-reaching in the market.Enterprises have competitiveness and the potential for sustainable development. It is not difficult to understand through this conclusion.“The quality goes up and the price goes down.”The phenomenon is the so-called cost-effectiveness.

2. Consumers’ consumption concepts have changed!Take the analysis of the mobile phone market. In the past, consumers did not consider what to do if their mobile phones got wet, and it was taken for granted that mobile phones did not have waterproof functions.At this stage, consumers are beginning to consider why their hands don’t have anti-protection functions. The most basic scenario is how to deal with rain.Therefore, the mobile phone market has begun to adopt preliminary IPX5 spray waterproofing.And it continues to be upgraded and improved to the IPX8 protection level represented by Apple mobile phones.

3. The scope and scenarios of consumers’ use are expanding!With the rapid development of the economy, people's living standards have improved. Consumers are experiencing a transition from survival to life, that is, consumers are beginning to enjoy life and enjoy the tasteful life brought by advanced high-tech products. Taking the speaker industry as an example, people are no longer satisfied with listening to music in a specific or fixed place. They want music when running, music when surfing, red wine and music when bathing. This has led to the development of speakers from indoors to outdoors to water and even more complex usage scenarios.

4. Technological progress solves more complex waterproofing requirements and drives the waterproofing demand for product peripherals and accessories!Take car cameras as an example. In fact, this product itself already has high waterproof performance. Because the pressure of the water gun used in car washing is very high, if the product structure is unstable or the IP waterproof level is low, it will easily get water, leading to repair or scrapping.Even though the body structure of the camera itself has been made very well, and the IPx waterproof detection level has been improved, another magical phenomenon was discovered: there is water vapor inside the lens!Affected by the rapid heating and cooling conditions, water vapor entered the interior of the camera along the horse copper wire of the camera's wiring harness.Therefore, the products of wire harness manufacturers that bring cameras must also be waterproof and undergo IPX waterproof testing. This opens up new waterproofing requirements for new industries. The waterproofing of wire harnesses will be discussed in another technical inspection technology topic.Take the following figure as an example: This is a wiring harness for a car camera. It is required that no gas leaks from any end during inflation testing, including the injection molded end, wiring harness surface, heat shrink sleeve, waterproof plug and other parts.

5. The original testing conditions for water testing are no longer recognized!According to the laboratory conditions of IP waterproofing, water is involved in the entire testing process, so the reasons for its inconvenience or elimination are as follows:

A. Contamination and secondary cleaning

B. Greater corrosion and damage to electronic components

C. Low efficiency and cannot be used in full inspection of the production line

D. Purely human judgment without scientificity and accuracy

E. Unable to perform quality tracking and traceability

5 In summary: The detection method using standard compressed air as the medium will become the mainstream of air tightness testing and IPX waterproof testing market; the industries that require testing will also continue to expand; testing technology and air tightness testing equipment will also be continuously improved to be closer to and cater to the needs of the market; and Shenzhen Hairuis Automatic Technology Co., Ltd., as a clear stream in the industry, as the mainstay of resisting and replacing foreign brands, is also constantly accepting market testing.The air tightness tester developed by it, also known as waterproof testing equipment, is highly intelligent, automated, and has good stability, and has entered the world stage - this is no longer a slogan or a vision, but a practical implementation.Don’t forget your original intention and move forward!
