Our diamond wire drawing die blanks are polycrystalline diamond (PCD) products produced under advanced high temperature and ultra-high pressure, diamond powder and a few of metal catalyst (Cobalt) sintered together with diamond-to-diamond bonding. They have not only high wear resistance, hardness and thermal conductivity but also high mechanical strength and tenacity. Our diamond die blanks are a unique product to draw a wide range of wire such as copper, aluminum, nickel, stainless steel and etc.
We have two series of diamond wire drawing die blanks: DB Series and TDB Series. They are available in 5 grades of grain size: 3 micron, 5 micron, 10 micron, 25 micron and 50 micron.
TDB Series are tungsten carbide supported die blanks, which have a polycrystalline diamond core integrally bonded to a tungsten carbide support ring. This feature makes it well for drawing with high intensity.
DB Series are self-supported die blanks, which include two types: DBL (Hexagonal) and DBR (Round). These blanks are suitable for all types of wire drawing applications especially where cost-cutting is required.
