Rubber seals play a significant role in the development of the national economy, serving as basic components and accessories in industries such as defense, chemical, petroleum, coal, transportation, and machinery manufacturing. In recent years, with the rapid growth of the economy, the rubber seal manufacturing industry has maintained double-digit growth. According to statistics, in 2010, enterprises above designated size in China's rubber seal manufacturing industry (with sales revenue of over 5 million yuan according to the National Bureau of Statistics) achieved a total industrial output value of nearly 8 billion yuan, a year-on-year increase of over 25%.

It is reported that there are nearly 300 large-scale enterprises in the domestic rubber seal manufacturing industry, and the industry generally presents a development trend of small enterprise scale and low technical level. From the perspective of enterprise economic types, private and foreign-funded enterprises account for over 95%, making them the main economic types in the industry; At the same time, enterprises are mainly concentrated in the East China region. In terms of the number of enterprises, sales revenue, and asset size, the East China region occupies a considerable share, and the market concentration is relatively high.

The rapid economic development has brought about an increase in fixed assets investment in major downstream industries such as the automobile industry and other machinery. The domestic market demand is strong, providing a huge market space for the rubber and plastic seal manufacturing industry. Many multinational companies have entered the Chinese market through joint ventures, partnerships, and other means, leading to intensified competition.

Fortunately, in the future, the industry will still benefit from government attention and support. With the improvement of product technology in China's rubber seal manufacturing industry, the transfer of the world's processing and manufacturing industry to China, and the role of price leverage, the quality of China's exported rubber seals has improved in recent years, and some products with high technological content have entered the international market. This situation brings great development opportunities to domestic rubber seal manufacturers.
