The polycrystalline  pcd wire drawing die blank is a diamond fine powder sintered by ultra-high temperature and ultra

high pressure process under the action of various metal (cobalt-containing) catalysts. 

Availabe Grain Size: 3um, 5um, 10um, 25um, 50um, etc.

Different choices of particle size can help customers increase mold life, improve wire finish, and control size. Carbide-

supported series products can bear greater pulling force, and are mostly used for manufacturing large-diameter die blanks

and drawing wires with thicker diameters.

The PCD blanks supported by the cemented carbide ring is characterized in that the polycrystalline diamond core and the

cemented carbide support ring are closely sintered into one body, and the support ring is used to improve the crack

resistance of the die blank, so that such products can withstand higher strength and high speed drawing.
