Polycrystalline Diamond is a diamond combo produced by diamond sintered with bond under high temperature and high pressure; It has very high wearability and high thermal stability. It's widely used in petroleum extraction, diamond machining, geology drill and mechanical processing tools.
PCD series is the first choice for nature diamond cut & polished nowadays.
The engineers of 3U corp. can control the wearability of polycrystalline diamond accurately for different industrial purposes. With different batch formulas and technologies; HDPC has made PCD well adopted by oil exploiters and drill manufacturer world widely.

TSP series Thermally Stable Polycrystalline (TSP) diamond can be manufactured into a variety of sizes and shapes (Cubes, Cylinders, Discs, Rectangles, Triangles, Spheres etc.) that can be inserted into cutting tools, drilling bits, reamers, wire drawing dies, and other wear-resistant components. Drill bits and reaming shells made with TSP diamonds are suitable for drilling in soft rocks with hardness below 7 degrees, such as lime rock, marble, shale, etc, and in medium to hard rocks with coarse grains.
