Technology & Products
Key Products
Raw materials (diamond grit, micropowder, PCD/PCBN composites); Key equipment (HTHP cubic presses, belt presses, MPCVD systems, SPS sintering, laser cutters, automation lines); Structured applications (superabrasive grinding wheels, cutting tools, PCD/PCBN inserts, diamond wire dies, CMP slurries); Functional applications (CVD diamond heat sinks, optical windows, diamond-copper composites, diamond semiconductor materials); Lab-grown diamond consumer brand (Dainuo/黛诺); Standards and testing services.
Technological Advantage
Dual synthesis technology (HTHP + MPCVD); 29 national-level R&D platforms including the State Key Laboratory of High-Performance Tools; holds 517+ cumulative patents (261 invention); developed China's first 0.01mm ultra-thin dicing blade; SiC grinding wheels with domestic market share exceeding 50%; proprietary ultra-fine diamond particle size consistency control technology.
Differentiation
Value Proposition
Full-stack superhard materials platform integrating R&D, equipment manufacturing, tool fabrication, and application solutions across the diamond value chain, backed by 60+ years of heritage from China's first synthetic diamond breakthrough.
How They Differentiate
Unlike pure producers (Huanghe Whirlwind, Liliang Diamond) focused on volume, Sinornach Diamond is a vertically integrated state-backed platform covering the entire diamond value chain with deep R&D heritage, national lab infrastructure, and strategic positioning as the industry "chain leader" (链主) for China's superhard materials sector.
