In recent years, the state has given certain support to the technology introduction, technological transformation, scientific research and development of the hydraulic and pneumatic seals industry, which has promoted the rapid development of the industry. China's agriculture, water conservancy, energy, transportation and other industries have developed rapidly, for which a large amount of mechanical equipment is needed to meet their development needs. With the improvement of industrialization and automation, these equipments need to be equipped with a large number of high-performance and high-reliability hydropneumatic and sealing components.

The status quo of the industry is optimistic. The composition of the sealing industry is generally speaking, and it has formed a situation of state-owned enterprises, private enterprises, three-funded tripods, and the output value basically accounts for one third. State-owned enterprises are stepping up reforms; a large number of private enterprises are rising rapidly; foreign capital is entering in large numbers, and major world companies are basically carrying out joint ventures, sole proprietorships, sales and other businesses in China, showing a trend of manufacturing industries shifting to China. In terms of technical level, the leading products of state-owned enterprises are mainly introduced and independently developed in the 1980s, basically at the international mid-range level; most of the private enterprises are mainly low- and mid-range products, but the funds are accumulating rapidly, using existing domestic technology to gather experienced talents The technological level has improved rapidly, and the quality, variety and services of its products have been constantly improved in competition; foreign-funded enterprises are mainly in the mid-to-high-end products. Their technical level is comparable to that of foreign countries, and they provide supporting facilities for high-end hosts and key projects required by domestic joint ventures and wholly-owned enterprises.

With the rapid development of China's economy, various types of mechanical equipment use hydraulic and pneumatic to realize the increasing transmission and control, and the technical requirements for seals are increasing. China's fluid power product market is developing rapidly, and it ranks first among developing countries except the United States, Europe and Japan. China's imports are also increasing, and the market has great potential for development.

The future market has huge development potential. With the improvement of industrialization and automation, mechanical equipment needs to be equipped with a large number of high-performance and high-reliability hydraulic and pneumatic seals. In addition to the century-old project construction of the Three Gorges of the Yangtze River, South-to-North Water Transfer, West-to-East Gas Transmission, West-East Power Transmission, Qinghai-Tibet Railway, and a large number of large-scale coal mines, oil fields, open-pit iron mines, power stations, airports, ports, high-speed railways, high-grade highways Key projects, as well as a lot of urban construction and residential construction. To this end, the increasing workload of earth-rock loading and unloading, coupled with the development of modern logistics and transportation, as well as the application of new processes, new technologies and new materials, will keep the domestic demand for construction machinery in the long-term growth. In short, the above products require a large number of high-pressure plunger pumps, high-pressure gear pumps, high-torque motors, wheel motors, multi-way valves, oil cylinders, pipe fittings, pipeline assemblies and oil filters, etc. The market for seals will face a new era of great development. Among them, construction machinery is a user of hydraulic products, accounting for 42.3% of the industry's sales, and the proportion will expand in the future, so the development trend of construction machinery is crucial. It is also reported that the imported hydraulic parts for excavators, road machinery, cement mixers, etc. produced by domestic enterprises reach more than 150 million US dollars each year. In short, the market for hydraulics and seals for construction machinery, maintenance and repair will face a new era of great development.
