Nowadays, in all walks of life, product quality has become a core factor in determining the competitiveness of enterprise brands, especially some high-precision products, the airtightness and waterproof function directly affects the product performance and safety in use.
So, how to effectively detect and grasp the sealing quality of the product? Air tightness tester is a good choice.Airtightness testing equipment can accurately identify whether there are air leaks in the product as a whole as well as in various parts of the product through the principle of the pressure drop method.
In fact, many industries make extensive use of airtightness testers in their production processes. For example:
- In the electronics industry, when developing new products or mass production, airtightness checks are implemented for mainframes, displays, and so on;
- The food industry tests various food packaging such as cans and bottled ware to ensure product quality and safety;
- The automotive industry also needs to know the degree of sealing when assembling body and engine parts;
- Medical equipment and instruments that have air leaks may pose a potential hazard for use.
......
Regardless of the industry, mastering the ability to hermetically seal products is an important part of quality assurance and risk reduction. Therefore.Choosing an effective and easy-to-use airtightness testing equipment becomes very important for the enterprise, this article will give you a comprehensive and popular buying guide from different perspectives.
Ⅰ.How does an airtightness tester work?
Now let's take a look at the most common principle of airtightness testing - the pressure drop method of testing - and see how it works:
The pressure drop method of detection is by setting a certain pressure difference between the inside and outside of the product, and then observing the pressure change to determine whether there is an air leak.
Specifically, the product to be tested is first placed in a profiling test fixture. Then, we will utilize the air tightness meter equipment to continuously supply a certain air pressure to the product inside. At the same time, we will also use precision differential pressure sensors to monitor the pressure difference between the inside and outside of the product. By analyzing these data, we can know whether there is any air leakage problem.
Depending on the positivity or negativity of the applied pressure, the pressure drop method of detection is subdivided into positive pressure detection and negative pressure detection.Positive pressure for types that are prone to clogging and leakage(waterproof test for any open, inflatable product)Negative pressure for products with large air leakage areas(for open type products (with holes for pumping))(This makes the pressure inside the product less than the external atmospheric pressure). In addition, both positive and negative mixed pressure detection modes are available for the widest compatibility.
Ⅱ.Why do I need to test for airtightness?
Whether the product is sealed or not directly affects its performance and service life. Only by mastering the airtight state, the enterprise can guarantee the quality of the product.
III.Which businesses need to buy?
Various industries such as new energy, household appliances, auto parts, consumer electronics, medical devices, security lighting, valves and pipelines, wire connectors, etc., use airtightness inspection in R&D, production and quality control.
IV.When should I buy?
It is suitable to arrange testing during new product testing periods, product upgrades, and regular quality inspections.
V.Where can I buy a leak detector?
There are many brands of leak detectors in the market, to choose imported instruments, you can go directly to ATEQ Adekai or its authorized channels to buy; if the pursuit of cost-effective, you can consider the domestic alternative instruments such as JCGK Ching-Chen Engineering and other manufacturers.
VI.How to choose the most suitable model?
Consider the need for testing accuracy, the type of product, and also evaluate various aspects such as price and after-sales service.
VII.What is the approximate price?
Airtightness tester belongs to professional equipment, generally we need to communicate and negotiate directly with the leak detector manufacturers or their authorized agents. The price often depends on the following factors:
Detection range size:The maximum test pressure supported determines the price.
Test accuracy:Supporting accuracy levels down to a few Pa or 0.1 Pa levels affects cost.
Number of test channels:The more samples of the product under test that are tested at the same time, the higher the cost of the equipment will be.
Whether customized workwear is required:Whether or not customized profiling fixtures are required will also add to the implementation costs.
Generally, in the domestic market, testers are available in a wide range of prices, from a few thousand dollars to tens of thousands of dollars.However, in fact, many low-end brands, in terms of technical design and practical application capabilities, may not always be able to fully meet the various needs of each customer.
JCGK is a national brand that has been working in the industry for many years. Although the price of the product is over 10,000 RMB, its testing accuracy and stability are widely recognized. We always adhere to the concept of rigorous research and development, and are committed to providing various industries with stable functions and cost-effective "assured choice".
In contrast, some internationally recognized brands are priced around tens of thousands of dollars to over a hundred thousand dollars though.Such as France ATEQ, Japan cosmos, the United States Uson, etc., but they often have better control in the detection accuracy, stability.
Moreover, some large-scale domestic listed companies often have higher testing needs than the general industry. Directly purchased ATEQ and other imported brands of equipment as standard equipment. This also corroborates the strength of their products from the application point of view.
VIII.Summarize
Whether you choose domestic or imported testing instruments, the most important thing is to clarify their own testing needs, and at the same time, consult senior friends in the industry to avoid stepping on mines, in order to purchase the most appropriate instrument.We believe that if you choose the right brand, you will be able to maximize your work efficiency.
If you have any questions about performing an airtightness test, consult with the manufacturer of the airtightness tester or a professional, such as Precision Engineering Airtightness.
