In recent years, industries such as engineering, wind power generation, construction, machinery manufacturing, and food have witnessed significant growth in the demand for high-quality components. This has led to a surge in the development of medium and small-sized enterprises. Due to the increasing production capacity and technological demands of various industries, there is a significant increase in the need for production methods. This has brought new market opportunities for component manufacturers. Currently, the application of rotary joints can be mainly classified into two categories: the supply of equipment configuration or complete supply technical solutions for raw material production equipment, which is mainly for mechanical processing, paper processing, textile machinery, chemical machinery, steel processing equipment, plastic machinery, printing machinery, food and processing machinery, construction machinery, solar panel material machinery, other industrial and chemical machinery, wind power generation and machine tool industries, etc., providing product support services for equipment manufacturers, or participating in or jointly developing rotary joints and related products that meet the technical requirements of the equipment based on their equipment's technical parameters. 2. The equipment technology transformation or single repair market of final processing enterprises, which mainly provides products and technical support for the most advanced product manufacturing enterprises. Through the analysis of the application status of rotary joints in various regions, we have found that, apart from the relatively advanced application basis and research and application technology research levels, there are also certain gaps in the raw material used and high-grade material used. Among them, the most significant aspect is the surface strengthening technology of metal materials and the backward production process of graphite materials, the precision processing level of products, and related technical standards, which have not reached the advanced level of foreign countries. The materials and processes for equipment post-processing and other aspects are also not up to the international advanced level.
