In recent years, the process of drilling holes and producing diamonds has become more efficient, with numerous challenges overcome. Today, diamond cutters are widely used in both industrial and daily applications, making it hard not to wonder: How are synthetic diamonds produced? And how did our city develop a thriving superhard materials industry?
To find out, a reporter recently visited Cangzhou Hehui Superhard Materials Co., Ltd., a leading player in this growing sector. The company has emerged as a "dark horse" in the superhard materials field, offering valuable insights into the industry’s development.
**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 production environment. Three standard factory buildings—material processing, synthesis, and product workshops—are lined up neatly, reflecting the company’s advanced infrastructure and efficient operations.
Inside the material workshop, raw materials are processed into graphite columns. In the synthesis area, these columns undergo high-temperature and high-pressure conditions using a six-sided top press to transform into diamonds. Finally, in the product workshop, diamonds are bonded onto substrates through high-temperature vacuum brazing, completing the manufacturing cycle.
As one of the city’s four key industries, the superhard materials sector plays a vital role in the local economy. Wang Zhanyong, Hehui’s chairman, recognized the strategic opportunities in the industry and aimed to capture a significant market share in an increasingly competitive landscape.
In 2012, Wang and his team moved to Ganzhou with a vision to build something new. Within less than ten months, the company completed land acquisition, construction, and startup, setting a record for rapid industrial development.
The hard work paid off. Hehui now operates as a high-tech enterprise specializing in R&D, production, and sales of high-grade synthetic diamonds and cubic boron nitride. In its first year, the company achieved sales of 110 million yuan, quickly establishing itself as a major player in the industry.
**Focusing on Innovation and Enhancing Product Competitiveness**
While China leads in output, there is still room for improvement in production technology compared to some developed countries. To bridge this gap, Hehui has focused on innovation, developing several core technologies and securing independent intellectual property rights. The company has also formed strategic alliances with renowned institutions such as Zhengzhou University and Zhongyuan Institute of Technology, as well as collaborating with experts from the U.S. and Canada.
In the synthesis workshop, a technician explained that the company has modified large-bore six-faced presses to produce high-quality diamond single crystals. These crystals are then sorted into three different product lines to meet various customer needs.
Hehui established a dedicated research center for superhard material tools, conducting in-depth studies on synthesis devices and innovating in equipment, processes, and materials. The company pioneered pre-made rod production lines and unique synthesis methods for diamond single crystals, while also developing independent catalyst production lines for cubic boron nitride.
These innovations have significantly boosted the competitiveness of Hehui’s products, which are now used across multiple sectors, including automotive, machining, oil drilling, and microelectronics. Customers praise the quality and reliability of the company’s offerings.
**Stabilize First, Expand the Market for Superhard Materials**
Despite decades of growth, the superhard materials industry remains promising. The national “Twelfth Five-Year Plan†highlights superhard materials as a strategic emerging industry, and the province has emphasized its importance in regional development. In 2013, the main revenue from the four key industries, including superhard materials, reached 92 billion yuan, solidifying its position in the national economy.
As a rising star in the industry, Hehui has grown steadily, aiming to become a leader. Over the past two years, the company has set production targets at 400 million carats annually, with a projected return rate of 100%. However, Wang Zhanyong remains cautious, emphasizing the need for steady growth rather than reckless expansion.
Hehui has adopted a differentiated strategy, positioning itself uniquely in the market. With the second phase of its project, investing 200 million yuan, the company will add 100 pieces of equipment, boosting its scale and output to new heights.
**Where Does the Enthusiasm for "Dare to Take Porcelain" Come From?**
In a highly competitive industry, strength comes from superior technology and service. As science and industry advance, the applications of superhard materials continue to expand. Hehui has developed specialized diamond products for subsea tunnel projects, gaining recognition and popularity.
While services may not directly generate profit, they enhance a company’s reputation. By combining strong technological innovation with excellent customer service, Hehui has built a solid foundation. This balance of "soft power" and "hard power" is what allows the company to "dare to take porcelain."
