Polycrystalline diamond composite(PDC) sheet is made of diamond particles and cemented carbide matrix sintered at 60,000 atmospheres, high temperature and high pressure above 1500℃, and has the high hardness of diamond and the high toughness of cemented carbide. It has high wear resistance and strong impact toughness. It is widely used in petroleum drills and geology Drill bit and so on.
Company Uking choose global high-quality raw materials with a unique interface structure. Through advanced high temperature and high pressure technology, the diamond layer is sintered more uniformly and densely, with a thickness of more than 2.5mm. While improving the wear resistance and impact resistance of the conforming sheet, it is especially improved The thermal stability greatly improves the durability of the PDC cutter.
Our company has the most advanced PCD performance test lab in China targeted on product development for the Oil & Gas drilling and mining industry. This enables our company to provide our customers with practical solutions for their PDC cutter needs.
PDC cutters for Oil & Gas applications including high impact cutter, abrasion resistance cutter, and general-purpose cutter. Besides standard PDC cutters, we make customized inserts for use in a variety of drilling tools.
The petroleum geological drill bit has the effect of impacting, crushing and shearing the formation rock when drilling into the formation rock because of the existence of the PCD composite sheet; therefore, the PDC bit composite sheet is used on the petroleum geological bit and can be well adapted to Soft, medium and hard strata.
1. High wear resistance
2. High impact resistance
3. Optimized interface between diamond and tungsten-carbide layers for excellent binding
4. High thermal stability
5. PDC drilling bit made of such PDC will break up rocks depending on shearing action when it works, which is more effective than crushing of rocks by roller cone bit or plowing and grinding of rocks by diamond impregnated bit
6. The serrate structure combination between polycrystalline diamond layer and hard alloy substrate allows more fixed combination between the two layers and more impact resistance of the whole PDC.
7. Best general performance available in the market
Drilling bits, Downhole tools, Mining tools and so on.
