The wire drawing die core is the core part of the diamond wire drawing die. According to the material, the die core can be divided into three types: PCD (polycrystalline diamond) die core, CVD diamond die core and single crystal diamond die core.
There is no metal bond in the silicon-based PCD core material, so the material can still maintain good thermal stability at 1000 degrees Celsius.
PCD silicon-based mold core has high temperature resistance and thermal stability up to 950 °C, suitable for drawing tungsten molybdenum, cutting wire, steel cord, stainless steel wire and other wires
