LINKUT could supply the professional PCD wire drawing die for your different kinds of drawing application.

Copper-plated wire drawing is a continuous plating process. Most manufacturers draw hard copper wire with hard wire drawing die. In recent years, many manufacturers have begun to use polycrystalline diamond wire drawing die.

Compared with cemented carbide, the polycrystalline diamond wire drawing die has a tensile strength of only 70% of the commonly used cemented carbide, but the hardness is 2.5 times that of the cemented carbide.
Thus, the polycrystalline diamond wire drawing die has more advantages than the cemented carbide wire drawing die.
The drawing die made of polycrystalline diamond has good wear resistance, uniform inner hole wear, strong impact resistance and high drawing efficiency. Therefore, the current polycrystalline diamond wire drawing die has gradually gained attention in the copper plating wire drawing industry.
Compared to carbide wire drawing dies, the life of polycrystalline wire drawing dies depends on the steady-state wear stage, and linear wear can extend the steady-state wear stage. Strict control of the size and angle of the hole type can greatly improve the life of the wire drawing die.
