With the rapid development of the automobile industry, automobile safety has always been the focus of automobile manufacturers and consumers.Because the use environment of cars is relatively complex, it is normal for consumers to travel in windy and rainy weather, so many parts of the car need to be waterproof, such as: car motors, car controllers, car headlights, and charging guns on new energy vehicles, car wiring harnesses, etc.

Normally, according to the waterproof standards of the automotive industry, the waterproof level of automotive accessories must reach IP66 orIP67 .So what does this waterproof level mean?IP refers to the protection security level.IP is the abbreviation of Ingress Protection Rating (or International Protection code), which defines the ability of an interface to protect against liquid and solid particles.IP67 means that without damaging the shell, 6 means that the accessory is not susceptible to dust intrusion, and 7 means that the accessory can protect the internal parts for no less than 30 minutes when immersed in water no more than 1m deep.

If the parts of the car cannot reach the corresponding waterproof level, the internal parts can easily cause damage during use, posing hidden dangers to our driving safety.

From the beginning of the establishment of Hirays Technology to now becoming a model in the industry, the air tightness testing of auto parts has always been our focus. From the initial testing of car sockets, car lights, and car wiring harnesses When it comes to testing automobile motors and cylinders, our testing cases and experience are the most abundant among our peers.With the country's promotion of new energy vehicles, Hirays Technology has become more and more mature in the air tightness detection technology of new energy vehicle charging guns and new energy vehicle battery packs. BYD, China's earliest electric vehicle, is also our partner.

In terms of air tightness testing of auto parts, stability and accuracy have always been of great concern to customers. The Hirays air tightness tester uses imported Honeywell pressure regulating valves, and the testing accuracy can reach 1pa. This accuracy is recognized by a national patent.The stability of Hirays air tightness detectors is well-known. Each instrument undergoes comprehensive testing and an eight-hour aging test before leaving the factory.
