Why Huanghe Whirlwind has become China’s largest base for lab-grown and industrial diamond production?
Henan Huanghe Whirlwind Co., Ltd. (Yellow River Whirlwind) was established in 1979, covering an area of 6.1 square kilometers and employing approximately 2,800 people. Listed on the Shanghai Stock Exchange in 1998 (Stock Code: 600172), the company currently has a total market value of about 20 billion RMB. Huanghe Whirlwind is a large state-controlled enterprise and a key high-tech company under China’s National Torch Program. It is a leading enterprise in China’s super-hard materials and products industry.
Over the past 40 years, the company has overcome numerous technical challenges, completing 173 provincial-level or higher scientific research projects and owning nearly 1,000 patents. Fifty-six of these achievements have reached a leading level domestically. The company has grown to become the largest production base for cultivated diamonds and industrial diamonds in China, solidifying its position as a pioneer in the super-hard materials and products industry.
Looking back on its development history, the reason why Huanghe Cyclone Co., Ltd. has become China’s largest cultured diamond and industrial diamond production base is mainly due to the following key factors:
- Developing press equipment with independent intellectual property rights
In 1996, Huanghe Whirlwind successfully developed the “UDS-6*1500T-I,” a cubic press with proprietary intellectual property. The company specializes in HPHT diamond presses, offering models such as DJ650, DJ700, DJ800, DJ850, DJ900, and DJ1000. These machines are constructed using 42CrMo material and feature an integrated “cylinder-beam” design to improve central positioning accuracy. Leveraging finite element data analysis, the company has optimized machine performance. The factory houses over 5,000 presses and employs a 5G-enabled intelligent visual monitoring and management system for 24/7 operations
- Strong R&D Capabilities
The company owns a national-level technology center and multiple provincial research platforms dedicated to innovation in superhard and advanced materials.
It employs a high-level R&D team with PhDs and masters, holding numerous patents in HPHT diamond synthesis, PDC cutters, and diamond micro-powder technologies.
Actively participates in the formulation of national and industry standards, driving technological progress in China’s diamond industry.
