At the 2nd China (Zhengzhou) International Abrasives Grinding Exhibition, the booth of Henan Huifeng Diamond Co., Ltd. stood out as a major highlight of the event, drawing continuous attention from domestic and international buyers. As China’s leading manufacturer of diamond micropowder, Huifeng remains committed to its core philosophy of focusing solely on one product, ensuring technological leadership and consistent quality. The company produces an impressive 40 million carats of diamond micropowder and 10 million carats of crushed diamond materials per month. Its products are highly sought after both domestically and internationally, with over 60% of its output exported to Europe, the U.S., Japan, Korea, India, and Southeast Asia, showing a steady upward trend in export volume.
**Fine Management for Superior Quality**
Huifeng follows a strategic approach known as “Four Super-One Stability,†aiming to maintain stable product quality while continuously improving in four key areas: super-fine, super-strong, ultra-pure, and ultra-fine. In terms of super-fineness, their diamond micropowder exhibits almost spherical crystal forms. On the ultra-fine front, they have successfully mass-produced 50nm single-crystal diamond powder and are preparing to launch 20nm production. For super-strength, they have developed three types of high-strength diamond powders, which they adjust according to market demand. In the ultra-pure category, they implement a special impurity removal process at the end of the production line, keeping impurities at just tens of parts per million (PPM).
**High-Strength Diamond Micropowder**
Huifeng's high-strength diamond micropowder is made from premium-grade diamonds processed through specialized techniques. It offers excellent thermal stability and wear resistance, making it ideal for applications in PCD, metal bond, ceramic bond, and electroplated products, as well as for processing hard alloys, glass, ceramics, and various stones.
**Ultra-Fine Diamond Powder**
Their ultra-fine diamond micropowder uses top-quality diamonds and advanced international grading technology to achieve sub-nanoscale and nano-scale particle sizes with excellent dispersion properties. This makes it suitable for ultra-precision grinding of hard and brittle materials such as fine ceramics, integrated circuit chips, gemstones, ferrites, quartz, and optical lenses. It also serves as an additive in wear-resistant composites, coatings, and lubricants, with wide applications in aerospace, precision machinery, optical instruments, and automotive industries.
**Ultra-Pure Diamond Micropowder**
Huifeng's ultra-pure micropowder is made from carefully selected high-quality diamonds and undergoes a special purification process to ensure clean surfaces and low impurity levels, typically in the ppm range. Surface modification ensures good dispersion in water-based and oil-based environments, maintaining high grinding efficiency and stability. It is widely used in the direct production of PDCs, grinding fluids, and polishing of materials with special surface requirements.
**Special Series for Customized Needs**
To meet specific customer demands, Huifeng has developed a range of specialized diamond micropowders, including those tailored for diamond composite sheets, grinding blocks, and diamond wires. Each variant is designed with unique properties to enhance performance, such as improved sintering in PDC products, stronger bonding with agents, and enhanced wear resistance.
**No Defects, No Complaints**
Huifeng upholds a service philosophy centered on “zero defects and no complaints.†A dedicated customer service center provides high-quality after-sales support. The company treats product quality as its lifeblood, employing advanced equipment and strict process control under ISO9001:2008 standards and GB6966-86 regulations. Every customer receives detailed records and samples for each shipment, ensuring full traceability and quality assurance.
**Rewarding the World, Winning the Future**
Recently, Huifeng announced a strategic cooperation with Academician Zou Guangtian, planning to establish an academician workstation at the company. This initiative aims to build a long-term collaboration between top academic teams and Huifeng, driving research on critical projects like diamond micropowder and nurturing innovation. The workstation will serve as a platform for collaborative innovation, talent development, and advancing the integration of industry, academia, and research. By addressing technical challenges and developing new technologies, products, and processes, Huifeng continues to strengthen its competitive edge in the global market.
