PCD (Polycrystalline Diamond) drawing dies are widely used in the wire drawing industry for drawing various types of wire such as copper, aluminum, steel, and other non-ferrous metals. PCD drawing dies are highly preferred due to their high hardness, wear resistance, and thermal conductivity.
Artificial polycrystalline diamond is formed by the fusion of synthetic diamond particles and metal bonding agent cobalt under high temperature and pressure. Polycrystalline diamond wire drawing dies have a long service life, which is 4 to 10 times longer than natural diamond molds and 50 to 500 times longer than cemented carbide molds. They also have good wear resistance, retention of mold hole roundness, strong tensile resistance, low mold cost, and superior quality of wire drawn, slightly inferior to natural diamond and superior to cemented carbide, Especially in the continuous high-speed wire drawing process, it shows its advantages.
Polycrystalline diamond is a hybrid material with the advantages of perfect surface polishing, minimal friction, and high resistance.
1. Durable
2. High efficiency
3. Wide range of available particle sizes and blank sizes
4. Excellent anti crack and damage performance
5. Smooth and predictable mold life
Wire drawing molds are widely used, such as high-precision wires used in electronic devices, radar, television, instrumentation, and aerospace, as well as commonly used tungsten, molybdenum, stainless steel, wire and cable, and various alloy wires, which are drawn using diamond wire drawing molds. Diamond wire drawing molds mainly use natural diamonds as raw materials, resulting in extremely strong wear resistance and very long service life.
Wire Range:
Wire drawing dies for flexible cords: gold, silver, platinum, brass, phosphor bronze, aluminum, etc.
Wire used for hard wire drawing dies: iron wire, stainless steel wire, nickel wire, chromium wire, molybdenum wire, tungsten wire, copper clad steel wire, etc.
PCD blanks allow us to cover an extensive range of die diameters from 0.030mm up to 38mm, as well as shaped dies (triangular, square, rectangular, oval, others shapes to drawing…) for the manufacture of profiled wires, bars and tubes.
PCD drawing dies are an excellent choice for drawing gold and silver wire for jewelry making. Their superior wear resistance, thermal conductivity, and surface finish make them an ideal option for high-volume production processes.
