We assist in identifying the correct PCD die based on your wire material, reduction ratio, die angle, and machine type. Support includes dimensional cross-referencing, die series selection, and compatibility analysis with OEM specifications from your drawing line.
We supply a comprehensive range of polycrystalline diamond (PCD) dies for wire drawing applications in the wire and cable industry, including units compatible with leading drawing machinery from Niehoff, Samp, Koch, Henrich, and Herborn. PCD dies are the industry standard for applications demanding high precision, extended tool life, and consistent wire quality across high-speed drawing operations.
Polycrystalline diamond dies feature a sintered PCD nib embedded in a metal casing, delivering exceptional hardness and thermal stability compared to natural diamond or carbide alternatives. This construction makes them ideal for continuous wire drawing of copper, aluminum, and steel wire, where abrasive wear and heat generation are critical factors in die performance and wire surface quality.
We offer PCD dies in a wide range of hole sizes, casing dimensions, and die geometries, including custom approach angles, reduction zones, bearing lengths, and back relief configurations. Whether you operate single-wire drawing machines, multi-wire drawing blocks, or bull blocks, we can supply dies matched to your exact reduction sequences and wire specifications — from coarse rod breakdown to ultra-fine wire finishing passes.
All dies are available with worldwide shipping and full technical support from our specialists, ready to assist with die selection, wear analysis, and dimensional verification to keep your wire drawing line running at peak efficiency.
