HNZN Diamond Technology Corporation
The company is an invisible champion company in the field of artificially cultivated diamonds in China. The main products of the company's superhard material business are synthetic diamond and cubic boron nitride single crystal and polycrystalline series products, composite materials, cultivated diamonds, high-purity graphite and products. According to the company's disclosure, the company ranks first in the world in terms of synthetic diamond production and sales and comprehensive competitiveness.
At present, the company has mastered the "20-50 carats cultivated diamond single crystal" synthesis technology, and 20-30 carats cultivated diamonds can be mass-produced and stably produced. The preparation technology of CVD cultivated diamond products has reached the international mainstream level. Mastered the centimeter-level high temperature and high pressure method CVD seed crystal preparation technology, which laid the foundation for expanding the application of functional diamond.
HNXF Diamond Technology Group
The company is mainly engaged in the production of hard materials and products, superhard composite materials and products, etc. The main products cover diamonds (such as industrial grade diamonds, gem grade diamonds), superhard composite materials (composite sheets), superhard tools, diamond wire saws, etc.
In 2015, the company realized the industrialization and market-oriented mass production of the "Gem Grade Diamond Series Product Development and Industrialization" project. At present, the company's 3-5 carat jewelry produced with cultivated diamonds has a stable market at home and abroad.
HNLL Diamond Technology Group
HNLL is a leading supplier of superhard materials in China. The company is mainly engaged in the research and development, production and sales of synthetic diamond products. It currently has three core product systems: diamond single crystal, diamond micropowder and cultivated diamond. On the basis of ordinary diamond single crystal synthesis technology, the company has obtained core technologies such as optimized nucleation control technology, high-pressure crystal form control technology, high-efficiency new purification technology, special-shaped single crystal separation and detection technology, etc., in the field of special-shaped diamond single crystal products. With technological breakthroughs, it became the earliest enterprise in China to realize the mass production of special special-shaped octahedral diamond spinels for super-finishing IC chips.
After nearly 3 years of research and development and testing, the company has made breakthroughs in the core production technology of ultra-fine diamond single crystals such as high-purity ultra-fine spherical powder catalyst technology, high-vacuum step reduction technology, and microwave purification technology. Crystal commercial production.
The company's production and sales of large-grain cultivated diamonds of 3 carats, 4 carats, and 5 carats and above have increased significantly. The higher sales price and gross profit margin of large-grain cultivated diamonds are expected to contribute higher profits to the company.
