In recent years, the process of drilling holes and diamonds has become more efficient, with many challenges overcome. The cutting stone now comes equipped with a diamond cutter, making it easier to use. Today, diamonds are widely used in both industrial production and daily life. But how exactly are superhard materials, like diamonds, produced? And how has our city developed a thriving industry around these materials?
Recently, a reporter visited Cangzhou Hehui Superhard Materials Co., Ltd. (Hehui Company), a leading player in the superhard material industry, to uncover the secrets behind its success.
**Seizing Opportunities and Creating a "Harmony Speed"**
Located in the East Industrial Park of Chenzhou City's Industrial Cluster District, Hehui Company showcases a modern, well-organized production environment. Three standard factory buildings stand side by side: one for material processing, one for synthesis, and another for product finishing. The spacious facilities, advanced equipment, and energetic staff all reflect the company’s commitment to efficiency and quality.
In the material workshop, raw materials are processed into graphite columns. In the synthesis workshop, these columns undergo high-pressure and high-temperature treatment using a six-sided top press, transforming them into diamonds. Finally, in the product workshop, diamonds are bonded onto substrates using a high-temperature vacuum brazing furnace to create the final product.
As one of the four key industries in the city, the superhard materials sector plays a crucial role in the local economy. Wang Zhanyong, chairman of Hehui Company, recognized the strategic opportunities in the industry and aimed to carve out a significant market share.
In 2012, Wang moved from Zhengzhou to Ganzhou, bringing together experienced partners to establish Hehui Company. Within less than 10 months, the company completed land acquisition, construction, and production setup, creating a remarkable achievement in the region.
The hard work paid off. Hehui now operates as a high-tech enterprise integrating R&D, production, and sales of high-grade synthetic diamonds and other superhard materials. In its first year, the company achieved sales of 110 million yuan, quickly establishing itself as a strong player in the industry.
**Focusing on Innovation and Enhancing Product Competitiveness**
Although China leads in the output of superhard materials, there is still a technological gap compared to some developed countries. To bridge this gap, Hehui Company has focused on innovation, developing independent intellectual property and core technologies. It has formed partnerships with leading research institutions such as Zhengzhou University and Zhongyuan Institute of Technology, and even signed technical agreements with experts from the U.S. and Canada.
Inside the synthesis workshop, a technician explained that the company modified a large-bore six-faced press machine to produce high-quality diamond single crystals. These crystals are then sieved and categorized into three different product lines to meet diverse customer needs.
Hehui also established a dedicated research and development center for superhard material tools. Through continuous innovation in equipment, processes, and materials, the company has developed large-cavity, high-quality synthetic diamond and cubic boron nitride production systems. It was the first to introduce a pre-made rod production line and a unique diamond synthesis process. For cubic boron nitride, the company owns complete, independent production lines for catalysts, rod processing, and synthesis techniques.
These innovations have significantly boosted the competitiveness of Hehui’s products, which are now widely used in automotive manufacturing, machining, oil drilling, microelectronics, and precision instrumentation.
**Stabilizing Growth and Expanding the Market**
Despite over 50 years of development, the superhard materials industry still holds great potential. The national “Twelfth Five-Year Plan†recognizes superhard materials as a strategic emerging industry, and the province has set it as a key focus for regional development. In 2013, the main business revenue from the four major industries, including superhard materials, reached 92 billion yuan, further solidifying its position in the national economy.
As a rising star in the industry, Hehui has grown rapidly and aims to become a leader. Over the past two years, the company has targeted 400 million carats of superhard materials production and a 100% annual return rate. However, Wang remains cautious, emphasizing steady growth rather than blind expansion.
To differentiate itself, Hehui has adopted a unique product strategy, avoiding direct competition with industry giants. Soon, the second phase of its 200 million yuan investment project will begin, adding 100 pieces of equipment and significantly increasing production capacity.
“Harmonious wisdom, Huitong future.†As a dark horse in the superhard materials industry, Hehui is steadily building its strength, step by step, toward becoming a true leader.
**Where Does the Passion for “Dare to Take Porcelain†Come From?**
“In the competitive superhard materials industry, without strength, it’s hard to gain market space and recognition,†said Wang. Strength comes from technology and service.
With the advancement of science and technology, the application fields of superhard materials continue to expand. Hehui has developed diamond-based anchor bolts for subsea tunnels, gaining popularity in the region. Its focus on high-quality products and excellent service has helped it stand out in the market.
While services may not directly generate profits, they enhance a company’s reputation. By combining strong technological innovation with superior service, Hehui has built both “hard power†and “soft power,†allowing it to thrive in the industry. This is the essence of “dare to take porcelain.â€
