Semi-Finished Dies Die Blank

Polycrystalline wire drawing dies are made of high-quality cores, which has the advantages of uniform texture, strong wear resistance, high finish, high precision and long service life. In the long time drawing process, the surface finish and accuracy of wire can be guaranteed. The inner diameter of the die can be produced within the range of 0.03-32mm.

Diamond materials are mainly divided into the following types:
Imported polycrystalline diamond: GE Compax made in US, Sumitomo made in Japan.
Domestic polycrystalline diamond: Sifangda CD material, Xinya CD material, Sipol CXD.

Natural diamond, abbreviated as ND, are formed naturally in the Earth's crust under high temperatures and pressures and are the hardest known material.


Single crystal diamond, abbreviation as AD, SD, SSCD, SMCD, MCD, is a synthetic diamond under controlled conditions, high purity, no impurities and high stability, these quality characteristics also make the material has high hardness and stable wear resistance.
