Domestic polycrystal drawing die with diamond powder, the cobalt or silicide catalyst,under high temperature and high pressure synthesis of diamond aggregates. The relative theory of surfaces, making two kinds of technique of diamond, characteristics of domestic cobalt based polycrystalline diamond is more close to the import of polycrystalline diamond and silicon, polycrystalline diamond, in addition to lower prices,physical properties and stability of products and imports of polycrystalline diamond and domestic cobalt based polycrystalline diamond has a larger gap.

Mold size range: 0.20mm - 20.00mm
