High-Performance Furniture Sliding Door Hydraulic Soft Closer – Metal Damper for Smooth & Quiet Closing

Hongfengzhiyang Products Factory is a high-tech enterprise which integrates scientific research, development, design and production of high-quality hinge damper, slideway damper, multi-functional buffer, door-moving buffer and intelligent buffer system. Since its establishment, we have adhered to the core concept of "technology-driven, quality-oriented", focusing on solving pain points such as noise, collision and unstable operation in the use of furniture and door hardware. To this end, we have built a 2,000-square-meter professional R&D center, equipped with thermal shock test chambers, fatigue life testers and noise detection instruments that meet international standards, enabling each new product to undergo more than 50,000 times of durability testing and multi-scenario simulation verification before mass production. With advanced international level and high precision automatic special equipment and production line, such as imported CNC machining centers with an error range of less than 0.01mm, fully automated assembly lines that can complete 1,200 units of product assembly per hour, and intelligent sorting systems that realize real-time traceability of parts, we have fundamentally eliminated human errors in the production process and ensured the consistency and reliability of each product. Based on advanced technology and modern standardized management, the products conform to national GB/T19001-2016 technical standards, and have passed the certification of ISO 9001:2015 international quality management system, as well as CE certification for European markets and ANSI/BHMA certification for North American markets, laying a solid foundation for global market expansion. Our R&D team, composed of 15 senior engineers and technical experts with more than 10 years of experience in the hardware industry, keeps close attention to the latest technological trends at home and abroad, and has successively obtained 28 national patents, including 8 invention patents. For example, our independently developed "self-adaptive silent buffer technology" can automatically adjust the buffer force according to the weight and closing speed of the door, reducing the closing noise to below 25 decibels—equivalent to the sound of a whisper—and filling the gap in the domestic medium and high-end buffer market. With good corporate reputation, sophisticated technology and exquisite and rigorous production process, high quality product quality and solid service, our products sell well in domestic and international markets, including 32 provinces and cities in China, as well as 45 countries and regions such as Germany, the United States, Japan, Australia and Southeast Asia. We have established long-term and stable cooperative relationships with many well-known furniture manufacturers and hardware distributors, such as IKEA's authorized suppliers and domestic leading custom furniture brands. In the domestic market, our products are favored by consumers for their excellent performance and durability, and have won titles such as "China's Trustworthy Hardware Product" for three consecutive years, winning unanimous praise from domestic and foreign customers. In the after-sales service sector, we have set up a 24-hour online technical support team and 8 regional after-sales service centers across the country, ensuring that customer problems can be responded to within 1 hour and solved within 48 hours. In the future, Hongfengzhiyang will continue to increase investment in research and development (planning to invest 15% of annual sales in R&D in the next three years), expand production scale by building a new intelligent factory in the East China Industrial Park, and strive to become a world-class provider of buffer system solutions that leads the development of the global hardware buffer industry.
