Introduction:
Sealing rings are essential engineering components used to prevent leakage of liquids or gases and ensure the proper functioning of mechanical equipment. This article explores the technology behind sealing rings, including material selection, manufacturing processes, innovative applications, and future development trends.

1. Material Selection:
   The choice of materials for sealing rings is crucial for their performance and durability. Traditional sealing ring materials include rubber, polyurethane, and polytetrafluoroethylene (PTFE). However, with advancements in technology, new materials such as silicone, fluororubber, and polyester are gradually being used in sealing ring manufacturing. These materials offer higher heat resistance, chemical corrosion resistance, and wear resistance, meeting the demands of various working environments.

2. Manufacturing Processes:
   The manufacturing processes for sealing rings involve mold design, material processing, and shaping. Advanced manufacturing techniques such as injection molding, compression molding, and extrusion molding are widely employed in sealing ring production. These techniques ensure precise dimensions and consistency, enhancing production efficiency and product quality.

3. Innovative Applications:
   Sealing rings find extensive applications in industries such as automotive, aerospace, petrochemical, medical equipment, and household appliances. With technological advancements, innovative applications of sealing rings continue to emerge. For example, high-temperature sealing rings are used in aerospace engines and high-temperature furnaces, while chemical-resistant sealing rings are employed in chemical equipment and oil drilling. Additionally, with the development of smart manufacturing and the Internet of Things (IoT), intelligent sealing rings are starting to emerge, capable of real-time monitoring of sealing status and providing warning information.

4. Future Development Trends:
   The future development of sealing ring technology will primarily focus on the following aspects:

• Green and Environmentally Friendly: Emphasis on the development of renewable and biodegradable materials to reduce environmental impact.

• High Performance: Enhancing the sealing rings' resistance to high temperature, pressure, and corrosion to meet more demanding working conditions.

• Smart Integration: Combining sensors and data analysis technology to achieve intelligent monitoring and predictive maintenance, improving equipment reliability and safety.

• Adaptability: Developing sealing rings that can adapt to different working environments and compensate for variations in temperature, pressure, and other factors.

In conclusion, the advancement of sealing ring technology through innovation and application plays a crucial role in creating a more efficient and environmentally friendly future, promoting the progress of transportation and machinery. Anticipating the increasingly important role of sealing ring technology in future developments, we look forward to its significant contributions to societal progress and sustainable development.
