The necessity of air tightness testing of automobile parts

As an important means of transportation for our daily travels, the safety of cars has always been of great importance to consumers and manufacturers.The sealing performance of auto parts is related to the safe driving of the car.Sometimes a small vulnerability in a component may cause a huge safety hazard.

Therefore, air tightness testing (tightness testing) of parts and components is the last safety guarantee that manufacturers make before products leave the factory.

With the improvement of waterproof detection technology, the current mainstream waterproof detection method is air tightness detection.Many parts in cars are easily damaged when exposed to water, so using water to test the sealing properties of car parts has been abandoned by many manufacturers.Air tightness testing is more convenient and more efficient than traditional water testing, and will not cause secondary damage to the product.At the same time, the air tightness tester uses compressed air as the testing medium. Air molecules are much smaller than water molecules, and the test results are more accurate than water.

1. High-sensitivity pressure sensing and adjustment unit, combined with advanced differential pressure software algorithm, the minimum resolution can reach 0.1Pa. This algorithm has obtained a national patent

2. Patented technology independently developed by Hirays,“IVT pneumatic sealing valve island”, greatly improving the test accuracy, ensuring the stability of the instrument, and the inflation speed is also greatly improved.

3. Multiple test functions: The instrument integrates two pressure forms, positive and negative, and 8 test methods: two pressure forms and five test methods can be programmed into more than 20 test functions.

4. It has more than 200 groups of subroutines. Each group of subroutines can be programmed independently and can be selected or combined to meet various complex testing requirements.

5. Full-touch large-screen intelligent operating system, graphical UI design based on the detection process, the operation interface is simple and clear, easy to teach and learn

6. A variety of pressure adjustment components and ranges are optional, with a wide air pressure range (-80KPA&-1MPa) optional.Optional electronic pressure regulating valve can realize multiple sets of pressure sequential testing

7. Multiple communication interfaces: built-in RS232 serial port, RJ45 network port, USB communication interface, LTP external I/O control port, supporting multiple communication protocols

8. Optional barcode scanning function and printer are available to facilitate product data management and quality traceability. The instrument history record can reach up to 200,000 items and can be exported to the computer in batches.

9. The standard volume identification function can automatically identify the volume of the sample to be tested, and measure and judge the leakage rate in a volumetric manner.

10. Ultra-high stability and ease of use have passed the rigorous test of the market.

The auto parts tested by Hirays Technology include: cylinders, car switch buttons, car lights, car controllers, new energy car connectors, etc.

A unique test plan is developed according to each test product. Some customers have a relatively large daily output. We can make double-station, three-station, and four-station non-standard air tightness testing equipment for customers in Shenzhen; some customers have less investment in instruments and equipment and insufficient budget. We will provide customers with single positive pressure instruments, which not only provides convenience to customers but also solves the problem of financial constraints.
