Four Core Product Lines
Covers the full range of CVD and PCD diamond products—from material R&D to custom manufacturing—meeting diverse precision engineering needs.
CVD Diamond Material
CVD Diamond (Chemical Vapor Deposition Diamond) is a high-purity polycrystalline diamond material grown via low-pressure deposition using direct-current arc plasma CVD technology. Free of metal binders, with high purity, dense structure, and stable performance, it is the next-generation superhard industrial material designed to replace natural diamond and PCD (polycrystalline diamond compact). Unlike traditional diamond materials, CVD diamond contains no cobalt, impurities, or pores, effectively solving industry pain points such as high-temperature softening, wear, and ablation associated with PCD. It offers five core advantages: extreme hardness and wear resistance, ultra-high thermal conductivity, high electrical insulation, corrosion resistance, and excellent mirror-polishing capability. As a premium substrate, it is the preferred choice for precision machinery, thermal management electronics, and superhard consumables.

PCD diamond material
Polycrystalline diamond (PCD) is a superhard composite material sintered under high-temperature and high-pressure (HPHT) conditions. Composed primarily of diamond micro-powder with cobalt as the binder, PCD is formed through sintering in extreme temperature and pressure environments. It is widely used in mass production for applications such as polycrystalline drawing die cores, correction pen strips, and composite cemented carbide substrates, with significant industrial demand.

PCD Diamond Products
Polycrystalline diamond (PCD) is the core material. Through processes such as high-temperature sleeving, laser drilling, grinding, ultrasonic treatment, wire polishing, milling, and turning, PCD is shaped into precision products. Leveraging diamond's extreme hardness for metal forming, it finds extensive applications—particularly in wire drawing dies and cutting tools.
