Zhejiang Huayuan Granted Patent for Self-Lubricating Nut

[Abstract]:Zhejiang Huayuan Granted Utility Model Patent for Self-Lubricating Clinch Nut to Enhance Assembly Lubrication

1. Patent Background and Technological Innovation
The latest announcement from the National Intellectual Property Administration shows that Zhejiang Huayuan Auto Parts Co., Ltd. (Stock Code: 301535) has been granted a utility model patent for a "Self-Lubricating Clinch Nut" (Patent No.: CN202521943843.5), authorized on October 14, 2025. This achievement marks a significant breakthrough in the company's fastener technological innovation.

The core of this patent lies in providing a clinch nut structure that achieves continuous lubrication during the threaded mating process. According to the patent specification, the self-lubricating clinch nut comprises a nut body, a protruding portion, and a circumferentially arranged groove. The protruding portion is designed to be inserted into the through-hole or threaded hole of the component to be connected, while the groove is specifically designed to be filled with grease. Multiple connecting slots are set at the edge of the protruding portion, linking the groove with the end and edge of the protrusion to form a complete lubrication channel system.

2. Technical Advantages and Application Value
The innovation of this design is mainly reflected in two aspects: First, it solves the problem of insufficient lubrication during the assembly of traditional clinch nuts. Traditional designs often provide limited lubrication only on the sheet metal surface, whereas the new design can continuously supply lubricant as the bolt is screwed in, effectively reducing assembly torque and minimizing thread wear. Second, by optimizing the lubricant delivery mechanism, it ensures that the grease reaches key contact areas precisely when needed, improving both lubrication efficiency and assembly quality.

This technology holds significant application value in fields such as automotive manufacturing, aerospace, and electronic equipment assembly. Particularly on automated assembly lines, stable lubrication performance can significantly enhance assembly efficiency and quality consistency. According to industry experts, this self-lubricating design can extend the service life of fasteners, reduce maintenance requirements, and decrease assembly issues caused by poor lubrication.

3. Corporate Technology Development Strategy
Zhejiang Huayuan's acquisition of this patent coincides with a period of rapid corporate growth. According to the latest financial data, the company achieved an operating revenue of 197 million RMB in the third quarter of 2025, a year-on-year increase of 16.72%. The cumulative operating revenue for the first three quarters reached 541 million RMB, up 18.64% year-on-year. While maintaining revenue growth, the company continues to increase its R&D investment and refine its technological innovation system.

The company's technical executive stated that this patent is a key outcome of the company's "technology-led, innovation-driven" development strategy. In recent years, Zhejiang Huayuan has continuously deepened its presence in the fastener sector, establishing a comprehensive R&D system that includes material research, process development, and product design. The newly patented self-lubricating clinch nut is a typical example of the company's targeted R&D based on market demands.

4. Industry Development Trends and Market Prospects
Currently, as the manufacturing industry shifts towards intelligence and precision, the performance requirements for fastener products are increasingly stringent. Particularly in fields like new energy vehicles and high-end equipment manufacturing, higher standards are set for the reliability, durability, and assembly convenience of fasteners. The application of self-lubricating technology perfectly aligns with this development trend.

Market analysis shows that the global clinch nut market is continuously expanding and is expected to grow at an annual rate of 6-8% over the next five years. Among them, high-value-added products with special functions are growing even faster. This patented technology is expected to help the company establish a technological advantage in an increasingly competitive market and expand into high-end application fields.

5. Impact of Technological Innovation on the Industry
The promotion and application of this patented technology are likely to have a positive impact on the fastener industry. First, it drives the elevation of industry technical standards, prompting more enterprises to focus on product innovation and performance optimization. Second, it provides customers with superior product choices, helping to improve the overall quality level of the entire industrial chain. Finally, it reflects the trend of Chinese manufacturing enterprises transitioning from "manufacturing" to "creation," enhancing the industry's technological confidence.

It is worth noting that this technological innovation also aligns with the national strategic direction of manufacturing transformation and upgrading. In the current policy environment where the state vigorously promotes the development of specialized, refined, differential, and innovative (SRDI) enterprises and encourages technological innovation in manufacturing, the acquisition and application of such practical patents hold significant demonstrative significance.

6. Future Outlook and Development Recommendations
Looking ahead, Zhejiang Huayuan stated that it will continue to deepen its technological R&D, further refine this patented technology, and bring it to market. The company plans to complete the mass production preparation for related products within the next year and conduct application tests with major customers. Meanwhile, the company will also develop a series of products around this core technology to meet the needs of different application scenarios.

Industry experts suggest that while promoting technological innovation, enterprises should also strengthen intellectual property protection and establish robust technological barriers. At the same time, they should focus on market demand research to ensure that technological innovations genuinely solve customer pain points and create practical value. Furthermore, strengthening cooperation with research institutes and universities to build an open innovation ecosystem is also an important pathway to enhancing corporate innovation capabilities.

Overall, the granting of the "Self-Lubricating Clinch Nut" patent to Zhejiang Huayuan not only demonstrates the company's technical strength but also reflects the firm steps of China's fastener industry towards high-quality development. Driven by technological innovation, "Made in China" is continuously breaking through technical bottlenecks and steadily advancing towards higher-end positions in the industrial chain.
