Dies manufactured with single crystal diamonds produce drawn wire with superior surface conditions and ability to maintain very tight diameter tolerances. This materials guarantees wire die hardness, accuracy, superior finish and extended die life.

PCD DIES is manufactured by forming a mass of diamond crystals and then applying a combination of heat and pressure. Through this process, the mass becomes a single unit with the diamond particles inter-grown to each other. The final product is extremely wear resistant, maintain tight tolerances and provide great surface finish. This material also has highly predictable die wear, thermal stability

The wire passes through the die in a general converging flow, its velocity increases as the wire approaches to exit. Since the volume of wire does not change, the wire elongates as the cross section reduces.
