Capacitor sealing testing equipmentHirays air tightness testing equipment is suitable for various capacitor sealing testing.Air tightness leak detection.Fast and stable.

The advancement of science and technology has made the fields involved become more extensive and complex, and the quality requirements for products have become more and more stringent, just like capacitors and relays.Nowadays, the requirements for air tightness and sealing are very strict.So what's going on?Seal testing equipmentWhich one is more advanced and reliable?There is still a lot of knowledge involved in ensuring the absolute sealing quality of capacitors. Among them, Hirays Automation focuses on high-precision air tightness.Seal testing equipmentfield, providing major manufacturers with the most advancedSeal detectordevice.

For tiny products such as capacitors and relays, air tightness testing is a difficult point because the casings of many products are opaque, many fuselage bodies are sealed as a whole without an inflation port, the product shape is uncertain, the internal space is very small, and the product production cycle is very fast. The traditional method of soaking in water is simply not feasible here, and Shenzhen HiraysiSeal testing equipmentThe detection method uses gas instead of water detection;

The gas attenuation method is used to detect whether the capacitor is sealed. Because the capacitor does not have an inflation port, we will make a replica precision sealing mold based on the shape of the capacitor, and then put the product into the mold. The instrument will inflate the mold in equal amounts, and then calculate the leakage value, and judge the quality of the product based on the leakage value.At the same time, the Hirays automated air tightness tester uses a very small internal space (1.5CC), which can ensure the stability and reliability of the test to the greatest extent.It is also equipped with an imported high-sensitive pressure 24-bit sensor, with a detection accuracy of up to 1PA (a normal person can blow hard to 15kpa, 1pa is 1/15000 of a normal person's breath), which is fully satisfactory for the waterproof test of electric toothbrushes. This detection accuracy can be described objectively, so that bubbles as big as a pinhole leaking every minute can be accurately detected.In this way, the work efficiency of waterproof testing has been greatly improved. The air-tightness test of various types of capacitors and relays can be detected by Hirays high-precision waterproof detector, which helps manufacturers and other electrical appliances to make products that are more in line with standards, so that the products can be recognized by major customers, suitable for various complex environments, and more perfect.

2. Testing methods.

First determine the test standards, such as the sealing test standard for capacitors and the IP67 waterproof test standard for bracelets.This is an international standard test requirement. The test method is relatively mature and I will not introduce it in detail. Currently, most high-pressure air tightness tests are non-standard customization. The test requirements are determined by the customer. The test standards need to be based on the product's use environment and sealing requirements.air pressure inside the product. The detection data is collected and analyzed by a high-precision seal detection system to calculate the leakage amount and obtain the leakage value. The leakage value is compared with the standard value to determine whether it is qualified.
