PRODUCT CENTER

Product Center

Geological composite sheet

Coalfield geological composite bit, specifically designed for drilling in coal seams and sedimentary rock formations, is manufactured through sintering a high‑strength polycrystalline diamond layer bonded to a cemented carbide substrate. This product combines the wear resistance of diamond with the impact toughness of alloy, delivering high drilling efficiency and extended service life in coal‑bearing strata while effectively handling challenging conditions such as interbedded shale layers and alternating soft–hard formations. It is ideally suited for underground gas drainage, hydrogeological drilling, and coalfield geological exploration, significantly enhancing overall drilling performance and economic returns.

Petroleum Drilling and Production Section

The petroleum drilling and production composite insert is specially developed for oil and gas drilling operations, fabricated by bonding a high‑quality polycrystalline diamond layer to a tungsten carbide substrate under ultra‑high pressure and temperature. The product exhibits exceptional wear resistance, thermal stability, and impact toughness, enabling it to meet the demanding high‑speed cutting requirements of complex formations such as shale, sandstone, and limestone. Widely used in PDC drill bits for oil, natural gas, and geothermal drilling, it significantly enhances mechanical rate of penetration and bit life, serving as a critical cutting component for efficient oil and gas extraction.

Cutting insert for cutting tools

Diamond composite inserts for cutting tools boast high hardness and excellent toughness. Our products feature superior stress control and are well suited for machining non‑metallic materials such as non‑ferrous metals and their alloys, engineering ceramics, stone, wood, carbon‑based synthetic wires, and more.

Mining tool blade

Mining tool composite inserts are specially designed for mining and tunneling equipment, manufactured by sintering a high‑strength polycrystalline diamond or cemented carbide layer with a tough matrix. These products combine exceptional wear resistance with excellent impact toughness, enabling effective performance in hard rock formations, fractured zones, and highly abrasive strata. They are widely used in coal‑mining shearer picks, tunneling machine cutters, breaker hammers, and other mining tools, significantly extending tool life and operational efficiency, reducing replacement frequency, and helping mines cut costs while boosting productivity.

Polycrystalline diamond

Polycrystalline diamond wire-drawing dies are drawing dies manufactured from synthetic polycrystalline diamond material. Thanks to their unparalleled wear resistance, excellent overall mechanical properties—including high strength and toughness—and superior thermal conductivity, they have become the preferred choice for modern, high‑efficiency, high‑precision, large‑volume metal wire‑drawing operations. They significantly enhance production efficiency, reduce manufacturing costs, and improve the quality of wire products, serving as a key indicator of technological advancement in the wire‑processing industry.

Single-crystal diamond

Single-crystal wire-drawing dies are manufactured using high‑quality synthetic single‑crystal diamond. They represent the pinnacle of performance in terms of surface finish, dimensional accuracy, and thermal conductivity, making them indispensable tools for producing the highest‑end, most precision‑engineered metal wires.

Cultured diamond (rough)

Lab-grown diamonds are genuine diamonds “grown” in a laboratory, with physical and chemical properties identical to those of natural diamonds. They are produced primarily using a six‑axis hydraulic press that replicates the extreme conditions deep within the Earth: at temperatures around 1,500°C and pressures of 50,000–60,000 atmospheres, graphite carbon is layered onto a seed crystal, where it crystallizes and grows over time. As gemstones, lab‑grown diamonds exhibit all the hallmark characteristics of natural diamonds—such as a Mohs hardness of 10 and dazzling fire—while commanding prices that are only 10% to 30% of those for natural diamonds. By sidestepping the ecological damage associated with open‑pit mining, they offer unparalleled purity and controllable quality, delivering exceptional value so consumers can afford larger, more brilliant stones without stretching their budgets.

Lab-Grown Diamonds (Loose Diamonds)

Synthesized using high‑temperature, high‑pressure (HTHP) or chemical vapor deposition (CVD) techniques, these diamonds exhibit controllable colors ranging from D (colorless) to Z (light yellow), with clarity and cut quality comparable to natural diamonds.

Diamond Color Change

Diamond color enhancement refers to a treatment method that uses artificial techniques to alter a diamond’s color, with the aim of enhancing its visual appeal or market value. Naturally occurring fancy-colored diamonds—such as pink, blue, and green—are extremely rare and command premium prices, whereas color‑enhancement technologies can replicate these hues at a lower cost, thereby meeting market demand.

PCBN cutting insert

This product series comprises high‑quality PCBN polycrystalline cubic boron nitride round inserts, manufactured using an advanced ultra‑high‑pressure, high‑temperature sintering process that tightly bonds micron‑sized CBN grains to a binder, which is then consolidated onto a cemented carbide substrate. (As shown in the figure, the black layer represents the CBN layer, while the silvery‑white layer corresponds to the carbide substrate.) These inserts exhibit exceptional hardness and wear resistance, making them a revolutionary tool for machining materials with high hardness and excellent wear resistance, significantly boosting machining productivity while reducing overall production costs.
