Today, China's manufacturing, nuclear power, and aerospace have become world-renowned major weapons. Cixi seals provide a "safety gate" guarantee for these major country's heavy weapons, lifting the "backbone" of high-end manufacturing for the nation.

As early as 37 years ago, Cixi Sealing Materials Factory developed flexible graphite composite sealing rings to support China's intercontinental synchronous satellite launch, thus opening the dream of becoming a major country in the heavy equipment industry. Nowadays, Ningbo Tiansheng Sealing Parts Co., Ltd. has won two national science and technology awards (second prize of National Science and Technology Progress Award and second prize of National Technology Invention Award). After eight years of sharpening the sword, its development of the main sealing C-ring for nuclear reactor pressure vessels has broken the global monopoly of the United States for over half a century, ensuring the smooth export of China's largest technological equipment export project, "Hualong No.1", and winning the championship of the Ministry of Industry and Information Technology in the manufacturing industry singles competition; The newly developed sealing structure for nuclear power plant pipelines has created the world's best level of sealing performance, which is one order of magnitude higher than similar international products. It has won the second prize of the National Science and Technology Progress Award and is used in most domestic nuclear power plants to replace imports and eliminate the threat of foreign supply interruptions. Ningbo Xinyuan Industrial Group has developed flexible graphite composite sealing rings for the two types of liquid hydrogen and liquid oxygen engines of the Long March 5 launch vehicle, laying a solid foundation for its smooth development and making important contributions to the first flight of the Long March 5 rocket. They have repeatedly broken international monopolies, filled domestic gaps, and demonstrated the pioneering spirit of daring to lead and stand at the forefront, the unwavering spirit of striving for goals and perseverance, the craftsmanship spirit of quality first and excellence, and are worthy of the nation and the times!
