Sichuan Natu Technology Co., Ltd., founded in 2017 and headquartered in Deyang, Sichuan Province, is a national high-tech company. It is recognized as a provincial-level "Specialized, Refined, Distinctive, and Innovative" (专精特新) enterprise and a municipal-level gazelle enterprise. The company specializes in chemical vapor deposition (CVD) diamond nanocoatings, focusing on the R&D, production, and sales of high-performance wear-resistant tools and advanced coatings.
The company’s independently developed CVD deposition furnace features a compact, automated design and enables the formation of diamond films ranging from micro- to nanoscale on cemented carbide substrates, significantly improving product performance. Its core product—diamond-coated wire drawing dies—offers a lifespan 10 to 100 times longer than conventional dies, securing over 30% of the domestic market and being widely exported to Europe, North America, and Southeast Asia. The company’s diamond-coated cutting tools deliver over 90% of the performance of imported equivalents at half the cost, and are widely used in aerospace and precision machining industries. In addition, the innovative boron-doped diamond (BDD) super-oxidation electrode for water treatment marks a breakthrough in domestic manufacturing. It offers a service life 10 times longer than traditional products, with mass production planned for 2025.The company has strong R&D capabilities, holding 6 invention patents and 25 utility model patents. It has established an Academician Expert Workstation in Deyang and maintains close collaborations with top universities, including Sun Yat-sen University and Southwest University of Science and Technology, supporting technological advancement in PVD coatings and composite wear-resistant materials. The production facility covers 78 acres (approximately 52,000 m²), with a 20% capacity expansion planned for 2025. Annual output targets include:
- 300,000 coated wire drawing dies
- 1,000 m2 of BDD electrodes
