Strong Partnership | Uniplasma joins hands with Huanghe Xuanfeng, and China’s first 8-inch diamond heat sink production line has been officially completed.

On February 28, the unveiling ceremony of Henan Fengyouchuang Materials Technology Co., Ltd. (hereinafter referred to as Henan Fengyouchuang), a joint venture established by Shenzhen Uniplasma and Huanghe Xuanfeng, was solemnly held in Xuchang. Attending the ceremony were Yang Zengjun, Party Secretary and Chairman of Xuchang City Investment Group; Quan Feng, Chairman of Shenzhen Uniplasma; Chai Bohao, Deputy General Manager of Shenzhen Uniplasma; Du Ping, Deputy Director of the Henan Branch of the China Development Bank; Li Ge, Chairman of Huanghe Xuanfeng; Pang Wenlong, General Manager of Huanghe Xuanfeng, along with other leaders.

It is reported that Henan Fengyouchuang was jointly established in September 2025 by Shenzhen Uniplasma and Huanghe Xuanfeng, with a primary focus on the research, development, and production of MPCVD polycrystalline diamond wafers. One party is a leading domestic enterprise in MPCVD technology, while the other is a leader in the superhard materials industry; this collaboration leverages the complementary strengths and technological synergy of both sides.

At the ceremony, Wang Shi, Chairman of Henan Fengyouchuang, stated that the company’s main products include 6- and 8-inch polycrystalline diamond flexible films and diamond thermal‑sink wafers ranging from 0.1 to 1 millimeter in thickness. These products feature controllable thermal conductivity and excellent uniformity, making them suitable for a wide range of critical applications, such as high‑power electronic devices, semiconductor lasers, optical modules, new‑energy vehicles, and aerospace.

He stated that the project has a total investment of RMB 1.2 billion, with Phase I accounting for RMB 360 million. It will be equipped with 50 MPCVD units, achieving an annual production capacity of 20,000 wafers and fully meeting the pilot‑scale and small‑batch needs of downstream chip‑packaging companies.

In his address, Uniplasma Chairman Quan Feng stated, “Today marks not only the unveiling of Henan Fengyouchuang, but also the successful completion of China’s first 8-inch diamond heat sink production line.”
 

He pointed out that, as AI computing power grows exponentially, it is posing unprecedented challenges to the thermal management capabilities of GPUs and data centers. As the ultimate thermal‑management material, the industrialization of diamond is now just around the corner.

He emphasized, “As one of the few domestic equipment companies that have fully mastered MPCVD diamond-growth technology, Uniplasma’s equipment has been running stably on the production lines of several leading customers. This deep collaboration with Huanghe Xuanfeng not only reflects the market’s high recognition of Uniplasma’s technical capabilities but also marks a crucial step in Uniplasma’s equipment transitioning from ‘laboratory‑grade’ to ‘mass‑production‑grade,’ officially entering the incremental market.”

In his address, Yang Zengjun, Party Secretary and Chairman of the Xuchang Municipal Investment Group, emphasized that the project represents a “vivid example of the deep integration of industrial and innovation chains.” As the controlling shareholder, the Xuchang Municipal Investment Group has consistently adhered to a development strategy that combines industry with capital.
 

He stated, “With the strong support of the Henan Branch of the China Development Bank, the collaboration between Yellow River Cyclone and Shenzhen Uniplasma marks a crucial leap for MPCVD diamond heat sink technology—from the laboratory to large-scale production and commercial application.”

Looking ahead, Henan Fengyouchuang has reached a new historical starting point, bearing not only the mission of technological breakthroughs but also the responsibility of injecting fresh momentum into the high-quality development of the local economy.

The commissioning of this production line not only marks a milestone in the deepened strategic cooperation between Shenzhen Uniplasma and Huanghe Xuanfeng, but also signifies that China has gained valuable influence on the global semiconductor thermal management stage.
