Most of the parts that can be seen on cars now have certain functions.，Even though some may look mundane or decorative, they often serve a purpose.The shark fin on the car is the antenna on the car. If the car is equipped with wireless transmitting equipment such as a cash register or a car phone, the signal on the car will become worse when the car is driving on a mountainous road. If a shark fin is installed, the signal reception in the car will be enhanced.

Shark fins are installed on the roof of the car and must withstand the test of wind and rain. The waterproof function has become a common concern of car shark fin manufacturers.At present, manufacturers generally need to meet the waterproof test requirements for car shark fins.IP68Waterproof level。

According to customer requirements, Hairis Technology used the following equipment and solutions for automotive shark fins:

Equipment used:Hai RuisiHCClassic Series Air Tightness and Waterproof Testing Equipment

Solution: Use direct testing method to test pressure50KPA,Inflation time10S, stabilization time10s, test time5S, leakage upper limit0.08KPA.The test fixture is designed based on the structure of the car shark fin. Since there are wires at the bottom of the car shark fin, the lower mold is divided into two layers to leave a suitable space for the wire harness.Place the car shark fin on the jig as required. After pressing the start button, the upper mold presses down and closes the lower mold. The jig uses a sealing ring to block the wiring port and seal around the product, forming a sealed cavity inside the jig.The instrument performs detection and monitors the changes in air pressure inside the fixture through processes such as inflation, pressure stabilization, and testing to detect the leakage value. The system automatically determines the leakage value based on the set parameters.OKorNG。

Car shark fin waterproof detection fixture

If a car has good waterproof shark fins, it will not only be safer to drive, but the shape of the car will also become unique.Hairis Technology's air tightness and waterproof testing equipment can accurately complete the waterproof test of car shark fins. Currently, this testing equipment of Hairis Technology is widely used among car shark fin manufacturers and is favored by many manufacturers.

At present, Hairis Technology has obtained a number of independent invention patents and utility model patents in the field of sealing testing.17software copyrights and a number of design patents. At the same time, Hairuis has also become the main drafting unit for the revision of the national "Electronic Product Waterproof Testing Standard", leading the development of the industry and becoming a model for the same industry to imitate.
