On November 8, 2022, the 14th China International Aviation and Aerospace Exhibition was held in Zhuhai, Guangdong Province. Five categories of WeimAI products, including metal accumulator, pipeline compensator, metal seal components, pressure sensitive components and special valves, were displayed at the exhibition, fully demonstrating the company's core strength in the development and manufacturing of key aerospace components. Weimai has participated in theAirshow China for three consecutive years. This time, Weimai will participate again, focusing on showing the fruitful results of the company's scientific and technological self-improvement and innovation in the past ten years. The company actively participates in national key projects such as space station construction, manned moon landing and large aircraft manufacturing, and builds industry-leading three core technologies of ultra-thin precision welding, stamping precision molding and high-quality shape co-control heat treatment, as well as key products for supporting applications of advanced materials such as stainless steel, titanium alloy, superalloy and aluminum alloy in the field of space and space. In this air show caused widespread concern in the industry. During the air show, Weimar also reached a package of cooperation intention with the affiliated institutions of Aerospace Science and Technology Corporation, Aerospace Science and Industry Corporation and AVIC Development Corporation of China to carry out all-round cooperation on metal hoses, accumulators, accumulators, special valves and other products used in rocket servo system, booster system, emergency lubrication system, ground equipment and other fields. The cooperation value is estimated to be nearly 100 million yuan. Weimai is committed to the aerospace oil and gas liquid field of high temperature, high pressure, low temperature corrosion resistant environment of sealing, compensation, pressure sensing, energy storage and energy storage technology achievements to the civil field, the company has been actively engaged in hydrogen energy, double carbon emission reduction, automotive and semiconductor industries, including a number of products for hydrogen energy high pressure valves have been officially put into production and delivery.

The Long March 5B Yo-4 carrier rocket blasted off from the No.1 launch station at the Wenchang Space Launch Site at 15:37:23 Beijing time on Oct 31. After about 493 seconds of flight, the capsule and arrow separated, and the carrier rocket accurately placed the Mengtian experimental module of China's space station into the initial orbital entrance scheduled for docking. At 4:27 PM on November 1, the space station's Mengtian experimental module successfully docked with the forward port of the core module after being launched into orbit, making the mission a complete success. During this mission, the accumulator cartridge, bellows assembly, pipeline compensator, metal hose and other products developed and produced by Weimai helped the Space station Mengtian experiment module successfully launch, again delivering excellent results. Dream day lab as most so far in China's largest spacecraft, China's space station the third part, also is the second science lab, by the working class, load class, goods of airlock module and resource module, take-off weight of about 23 tons, mainly used for developing application and space science experiments, participate in the assembly station management, automatic air brake cabin can support the goods in and out of the tank, Provide support for in-cabin surgery experiments. In the vacuum exhaust system of Mengtian experimental cabin, the metal hose produced by Weimai plays an important role. "POGO" vibration (longitudinally coupled vibration) is not a strange term for aerospace practitioners. During rocket flight, a longitudinally unstable low-frequency vibration will be generated, namely "POGO" vibration. Such vibration will cause the failure of various equipment in the rocket fairing, and also have a great impact on the structure of the rocket itself, especially a rocket with a large carrying capacity like the "Long March 5B". In order to eliminate the negative effects of "POGO" vibration, it is necessary to use the accumulator (hydraulic pneumatic accumulator with metal bellows, which is a hydraulic oil storage device developed based on the compressibility of gas) on the booster. A total of 24 accumulator cartridges are used on the four boosters of the Long March 5, all of which are produced by Weimai and play an important role in the smooth flight of carrier rockets. It is reported that Wemai, as a professional pipeline valve system solution provider, focuses on the gas and liquid field of high temperature, high pressure, low temperature corrosion resistant environment sealing, compensation, pressure sensing, energy storage and other technologies. The company was founded in 2008 and officially entered the aerospace market in 2009. After years of accumulation, its products are widely used in aviation, aerospace, Marine, gas turbine, high-speed rail, automobile and other fields, and it has become an aerospace precision component manufacturer integrating production, manufacturing, research and development.
