High Precision Diamond Drawing Die

Our High Precision Diamond Drawing Die is engineered for the most exacting wire drawing applications, where micron-level accuracy, surface perfection, and extended tool life are non-negotiable. Featuring a meticulously crafted natural diamond or polycrystalline diamond (PCD) bore—securely mounted in a high-strength tungsten carbide or alloy steel housing—this die delivers exceptional dimensional control and consistency, even during continuous, high-speed production of fine and ultra-fine wires.

Designed for drawing conductive and specialty wires—including copper, aluminum, gold, silver, platinum, nickel alloys, and stainless steel—the die ensures outstanding roundness, minimal surface defects, and uniform mechanical properties throughout the drawn wire. The extreme hardness and smoothness of the diamond bore drastically reduce friction and wear, enabling stable performance over tens of thousands of meters of wire without degradation in quality.

This high-precision tool is widely used in industries that demand the highest standards, such as microelectronics, medical device manufacturing, aerospace, fiber optics, and high-end electrical cabling. Its ability to maintain tight tolerances at sub-micron levels makes it indispensable for advanced applications like magnet wire, bonding wire, and sensor components.

Each die is custom-engineered with optimized inlet angles, bearing lengths, and exit profiles to match specific material types, reduction ratios, and line speeds. Rigorous inspection using laser interferometry and optical metrology guarantees conformity to exact specifications. The High Precision Diamond Drawing Die offers unmatched reliability, productivity, and wire quality—setting the benchmark for excellence in precision metal forming.
