Die casting-application cases
The popularity of new energy vehicles and the trend of lightweighting have driven the output of my country's aluminum alloy die-casting industry to fluctuate year by year. In 2023, the output of aluminum alloy parts will reach 7.91 million tons, a year-on-year increase of 4.8%.And consumers have increasingly higher requirements for vehicle safety, and the sealing performance of the die-cast shell has become one of the key points of vehicle safety. The high performance of the Hirays HQ hydrogen and nitrogen leak detector ensures that every new energy vehicle meets the required safety standards.
Analysis of successful cases: die castings↑Customer die casting productsCustomer demand: Leakage detection of die-casting parts, and determination of the leakage point location of defective products; the detection pressure applied to the product to be tested is 1.8MPa, and the leakage rate does not exceed5*10-6mbar·L/s, it is a qualified product, but it is a defective product.The customer's original plan: adopt the traditional air tightness testing method, use compressed air as the medium to test the die castings, and judge the qualification of its sealing performance through the leakage value.becauseThe detection accuracy of air tightness meter is generally 10-4Pa, cannot meet the fine detection standards.Difficulties of the plan:Due to the complex process of die casting.During the die-casting process, "blastic holes" or penetrating cracks appear inside, which are not visible to the naked eye. When soaked in water, tiny bubbles similar to "a thin line of sky" leak out. Traditional air sealing cannot detect this tiny leak at all.Based on the product characteristics of die-casting parts, Hirays generally recommends customers to use the HQ hydrogen and nitrogen leak detector with higher accuracy and more complete functions to detect leaks on them.↑Heruis die casting solutionsThe HQ series hydrogen-nitrogen leak detector has high integration and compact appearance, and is suitable for appearance detection of complex workpieces in multiple scenarios.It has two detection methods: collection + sniffing, and the minimum leak detection rate can reach5*10-7mbar·L/s, to meet the high-precision inspection needs and leakage finding needs of die-casting customers.And the lowest cost can be controlled at 0.02 yuan/time.It can replace most helium inspection test scenarios and is 1/20 of the cost of helium inspection.① Hiraysi provides a one-stop overall solution of "instrument-test platform-jigs-accessories" to reduce customer procurement time, complete production line deployment faster, and help improve delivery efficiency.② Equipped with HQ hydrogen and nitrogen leak detector, it can better meet the detection needs of die castings than ordinary air tightness instruments: it has higher accuracy, and the handle can also determine the location of the leak point through the sniffing mode, which facilitates customer information collection and process improvement.↑Hiraysi HQ series hydrogen and nitrogen leak detector③HiraysiThe jig processing accuracy can reach 0.02mm.The accuracy of HQ series hydrogen and nitrogen leak detector can reach 5*10-7mbar·L/s, which is more in line with the high-precision testing needs of die-casting customers.Hai RuisiRelying on core independent research and development capabilities,A complete product matrix has been built to accurately cover everything from10-1to 10-11wide range of detection accuracy requirements, providing the automotive industry with“Instrument-test platform-jigs-accessories”One-stop auto parts leak detection equipment is convenient to purchase, which greatly speeds up the customer's production line deployment process.
