The sealing industry is an important foundational industry widely used in various industrial fields, such as petrochemicals, coal chemicals, engineering machinery, metallurgy, pharmaceuticals, food, textiles, automobiles, household appliances, etc. According to the classification of national economic industries, the sealing industry belongs to the rubber and plastic products industry in the manufacturing industry, specifically classified as other rubber product manufacturing industries.
Market size: In 2021, the demand for seals is about 1.603 million tons, with a total industrial output value of nearly 20 billion yuan and a market size of 157.1 billion yuan.
Technological development: With the advancement of technology, the sealing industry is moving towards high-end development, and the technical requirements for sealing are becoming increasingly high. Rubber seals have gradually replaced metal seals as the mainstream in the market due to their excellent elasticity, mechanical strength, and other characteristics.
Policy support: National and local government departments have issued multiple support policies for mechanical basic components such as seals and sealing materials, promoting the development of the industry.
Industry chain: The upstream of the sealing industry is mainly the supply of raw materials, including steel, alloys, rubber, plastics, ceramics, etc; The midstream is for the production and supply of seals; Downstream applications are widespread, including petrochemical, coal chemical, engineering machinery, metallurgy, pharmaceuticals, food, textiles, automobiles, household appliances, etc.
Industry classification: The sealing parts industry belongs to the rubber and plastic products industry, specifically classified as other rubber product manufacturing industries.
Although there is a certain technological gap in the sealing industry, with the improvement of domestic manufacturing level, global hydraulic sealing and high-pressure manufacturing bases are constantly shifting to emerging developing countries such as China, and the Chinese sealing industry has ushered in a period of leapfrog development. It is expected that in the future, with the continuous progress of technology and the continuous expansion of the market, the sealing industry will usher in greater development space.
