March 25th,Sinomach Precision MachineryThe announcement states that the subsidiary will do the following:Guomachine Diamond (Henan) Co., Ltd.To invest 380 million yuan in establishing a presence in Hami City, Xinjiang.Guoji Jingang Diamond Crystal Technology (Xinjiang) Co., Ltd.The company will invest 378 million yuan to purchase 400 sets of high-power MPCVD equipment自制 by Jingong Ruiyi Technology (Henan) Co., Ltd. (a wholly-owned subsidiary of SAMS), as well as supporting equipment such as laser cutting machines and hydrogen generators, to build a pilot production line and industrial production line for functional diamond materials.
As the "king of materials," diamond exhibits extensive market prospects in high-end manufacturing sectors such as electronics, optics, and thermal management due to its extremely superior physical and chemical properties. In recent years, with breakthroughs in MPCVD (microwave plasma chemical vapor deposition) technology, the industrialization of large single-crystal diamonds has accelerated. However, due to relatively high production costs, its market penetration is still somewhat restricted.
At this critical juncture of industry transformation, China National Jewellery & Machinery Group Corporation has increased its investment in functional diamond materials, aiming to secure a commanding position in both technology and the market. This move not only underscores the company's firm confidence in the future market of diamond materials but is also expected to promote the large-scale development of the domestically produced monocrystalline diamond industry.
FromFrom the perspective of the industrial chain来看CNI's investments cover multiple high-value applications of diamond, including core areas such as heat sinks, optical windows, semiconductors, etc. In particular, in the field of electronic-grade diamond materials, due to their excellent thermal conductivity and electrical properties, they are considered one of the important contenders for the fourth-generation semiconductor materials. Currently, with the increase in power density of electronic devices, traditional heat dissipation materials (such as copper, aluminum, silicon carbide, etc.) are gradually unable to meet the needs of high-end applications. Diamond, with its far superior thermal conductivity compared to other materials, is regarded as an ideal solution for thermal management.
One of the core goals of Guojijiangong's investment is to enhance the production capacity of electronic-grade diamond through the expansion of MPCVD equipment, providing more competitive thermal materials for high-heat-flux electronic devices. This layout aligns with the current global semiconductor industry's trend towards high efficiency and low power consumption, laying a foundation for the company's future deep penetration into the semiconductor and advanced electronics markets.
From the perspective of market demand,The functionalization applications of diamond are gradually opening up, particularly in areas such as cultivated diamonds, high-power lasers, infrared detectors, microwave communications, and photolithography systems. The high optical transparency, hardness, and chemical stability of diamond make it an irreplaceable material for many advanced optoelectronic devices. At the same time, with the gradual reduction in the production cost of diamond materials, the consumer electronics sector is also beginning to pay attention to the application prospects of diamond in heat dissipation management in devices such as mobile phones and tablets. This trend suggests that in the coming years,The market scale of functional diamonds is expected to witness exponential growth.
From the perspective of regional layout,The choice of Hami in Xinjiang is not accidental. As a manufacturing承接地 in the western region, Hami has a relatively complete industrial foundation and lower operational costs. At the same time, the Xinjiang region has strong policy support for the new energy and new materials industries. In addition, Hami serves as an important node for China to radiate to the Central Asian market, holding certain strategic value for the future export of diamond materials and the exploration of international markets.
At the beginning of March, the Hami diamond industry has been making frequent moves. On March 4th,Xinjiang Runjing Technology Co., Ltd.The first batch of products from the 1 billion carat annual production capacity synthetic diamond project production line has rolled off the assembly line in the southern circular economy industrial park of the Hami High-tech Industrial Development Zone, marking the official completion and commissioning of Xinjiang's first diamond production line.
In addition,Xinjiang Carbon-based Core Material Technology Co., Ltd.Signed contracts successively with the Management Committee of the Guangzhou Industrial City (Park) in Shufu, Xinjiang, and the Pishan County of Hotan Region, Xinjiang, to respectively build a project for the annual production of 1.5 million carats of diamond chip substrates and a project for the annual production of 1.5 million carats of diamonds. The first phase of the annual production of 1.5 million carats of diamonds project will build 20 sets of industrial-grade deposition equipment.500,000 carats of electronic-grade diamondwith a purity of 99.999% (5N level), focusing on breakthroughs in 8-inch single-crystal substrate technology.
However, despite the broad investment prospects of Guojijinggong, it still faces certain challenges. Currently, the functional application market for large single crystal diamonds produced by the MPCVD method is still in its early development stage, particularly in the electronics-grade market, where the commercialization progress remains uncertain due to technical maturity and production costs.
In addition, the global diamond materials market is becoming increasingly competitive, with foreign companies such as Element Six having established certain technological barriers in the electronic-grade diamond field. Domestic enterprises face the challenge of breaking through key technologies and achieving domestic substitution. In response, Guojijinggong plans to enhance its market competitiveness by increasing R&D investment, collaborating with universities and research institutions, and continuously optimizing the MPCVD process to improve the quality and scalability of diamond materials.
Overall, CIMC's investment in the industrialization of functional diamond materials aligns with the global trends in the new materials industry and meets the strategic needs of the country for the next-generation semiconductor and high-end manufacturing sectors. By continuously enhancing its technological capabilities and expanding production capacity, the company is expected to become a significant player in China's functional diamond materials market in the coming years and may even secure a foothold in the international market.
Currently, the company has successfully developed key technologies and industrialization techniques for diamond synthesis using MPCVD methods. Products such as heat sinks and optical windows have achieved breakthroughs from laboratory技术研发 to practical applications, realizing sales on the scale of millions of yuan.
Of course, the future success of market application will depend on the coordinated advancement of multiple factors, including technological breakthroughs, cost control, and market development. However, it is foreseeable that, with the continuous growth in global demand for high-performance materials, the functional diamond industry will become an important growth point in the field of material science and technology, and Guojijinggong is at the forefront of this industrial transformation.
