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 performance are also very strict.So what kind of air tightness leak detector has good reliability and high efficiency in capacitor seal testing?There is still a lot of knowledge involved in ensuring the sealing performance of capacitors. Among them, Hirays Automation focuses on the field of high-precision sealing testing and has long-term provided high-quality air tightness leak detectors to major manufacturers.Seal testing equipment。

For tiny products like capacitors and relays,Air tightness leak detectionIt is a difficulty, because the casings of many products are opaque, many fuselage 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. The Shenzhen Hirays testing method uses a gas-tightness tester instead of water testing;

capacitanceSeal testIt is detected by the gas attenuation method. Because the capacitor does not have an inflation port, we will make a replica precision sealing mold according to the shape of the capacitor, and then put the capacitor into the mold. The instrument will inflate the mold in the same amount, and then calculate the leakage value. Based on the leakage value, we can judge the excellent sealing performance of the capacitor.At the same time, the air tightness leak detector has a very small internal space (1.5CC), so that it can ensure the maximum leakageSeal teststability and reliability.It is also equipped with an imported high-sensitive pressure 24-bit sensor, and the air tightness leak detection accuracy can reach 0.1PA (normal people can blow hard to 15kpa, and 1pa is 1/15000 of a normal person's breath). It can fully satisfy the capacitor sealing test. This detection accuracy can be described objectively, so that bubbles with the size of a pinhole leaking every minute can be accurately detected.
