The seal companies in China have always been not very clear about their positioning, blindly producing, and lack of matching and cooperation with the host companies. It can be said that the vast majority of seal products of domestic companies are only produced in batches according to a unified standard. They do not care whether their products can meet the matching requirements of the mainframe products on the market. They are blindly pursuing their own factory volume, but they are used in host applications. It is difficult to guarantee mechanical stability.
Although the industry has made a lot of development in recent years, but these are still far from meeting the needs of other industries for the development of standardized and serialized products for all types of rubber seals, especially when compared to international advanced countries, regardless of the products in China. There is a considerable gap between quality and product variety.
Industry insiders pointed out that in order to meet the increasingly high requirements of human beings for environmental protection, the ISO14000 standard has begun to be taken seriously by Chinese companies, and people's requirements for sealing have become stricter. On the other hand, the new standard objectively brings about the redistribution of the market. The new and more stringent quality standards will become the biggest obstacle to the export of sealed products in China; it will also become a killer for foreign companies to enter the Chinese market. Enterprises that do not pay attention to technological progress will be eliminated in the next five years.
The industry output value of the seal industry as a whole cannot be compared with the machinery industry of the national leader. However, seals have a major impact on the overall performance and service life of mechanical equipment. Therefore, only the continuous production of high-quality seal products can promote the development of the machinery industry.
Sealed products are an integral part of the pharmaceutical equipment industry
In recent years, the production and quality of our sealed products have gradually entered a new stage and new period. The application in the pharmaceutical machinery and equipment is also growing day by day, and the same requirements are constantly increasing, which makes the sealed product industry face an upgrade situation.
