Self-supported PCD Die Blanks
Good wear resistance; High hardness; Better heat resistance.
The pcd wire die drawing 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.
During the sintering process, high-strength diamond bonds are formed between the diamond
crystallite particles, and the diamond micropowder particles are strongly bonded together to form
polycrystalline diamond (PCD). The pcd die blanks produced by the method has high wear resistance,
hardness and thermal conductivity, and has good mechanical strength and toughness, and is suitable
for drawing non-ferrous metals such as copper, aluminum and nickel, stainless steel and various alloys wire.
CDS Series: Cobalt bond Self-supported PCD Die Blanks
The Cobalt based drawing die blank without outer ring support is divided into hexagon and round
shape. These sizes of pcd die blanks are suitable for all types of wire drawing applications,
especially for wire drawing dies that consume a large amount of material.
Availabe Grain Size: 3um, 5um, 10um, 25um, 50um, etc.
Different choices of particle size can help customers increase mold life, improve wire finish, and
For drawing copper wire, aluminum wire, tungsten wire, nickel wire, high carbon steel cord, and other alloy
Can be used for wet and dry drawing applications; from rod-size to fine-size.
Maximum recommend bearing diameter for “soft” non ferrous wire . “Hard” wire diameter normally should
not exceed 65% of this diameter.
