In industrial use platforms, a mechanical seal is a material or component that prevents fluid or solid particles from leaking between adjacent joints and prevents external impurities such as dust and moisture from entering the machine equipment. Seals are important basic components in industrial production. According to their different functions, they can be divided into shaft seals, hole seals, dust-proof seals, guide ring seals and fixed seals. Sealing materials are widely used in household appliances, automobiles, construction machinery, aerospace and petrochemical industries, and play a pivotal role in the national economy.


According to the '2020-2024 China Seals Industry Market Supply and Demand Survey and Consulting Report' released, there are a large number of seals manufacturers in my country, and they are mainly distributed in Shandong and the Yangtze River Delta region. Generally speaking, my country's seals manufacturers summarize the competition In recent years, with the rapid development of the domestic economy, corporate mergers and acquisitions have increased, and the market concentration of seals has gradually increased. Compared with international sealing manufacturers, my country's sealing manufacturers have certain differences in scale and product quality.

Since 2012, the output of mechanical seals in my country has shown a trend of bumpy growth. In the domestic seal production industry, mechanical seals occupy the main position, accounting for more than 70%, followed by rubber seals, accounting for about 18%. In recent years, with the rapid development of my country's industrialization and automation, the market has put forward higher requirements for the performance and reliability of mechanical equipment, gradually promoting the transformation and upgrading of the sealing industry in the direction of high-end and customized.
