PCD Diamond Die

Our PCD Diamond Die is a high-performance wire drawing tool engineered for superior durability, precision, and efficiency in demanding industrial applications. It features a polycrystalline diamond (PCD) insert—created by sintering micron-sized diamond particles under high temperature and pressure—bonded securely within a robust tungsten carbide or steel housing. This advanced composite structure combines the extreme hardness and wear resistance of diamond with the toughness and thermal stability of the supporting matrix.

Ideal for drawing non-ferrous wires such as copper, aluminum, brass, and their alloys—including high-silicon aluminum and other abrasive conductive materials—the PCD Diamond Die delivers consistent wire dimensions, excellent surface finish, and extended service life far beyond conventional carbide or single-crystal diamond dies. Its uniform microstructure eliminates grain orientation issues, ensuring isotropic wear and stable performance over long production runs.

Commonly used in electrical cable, automotive wiring, transformer, and electronics manufacturing, this die excels in high-speed, high-volume operations where minimizing downtime and maintaining wire quality are critical. The PCD bore resists chipping, cracking, and deformation, even under aggressive reduction ratios and continuous use.

Available in single-hole or multi-hole configurations with custom-designed geometries—including tailored inlet angles, bearing lengths, and exit profiles—our PCD Diamond Die is fully customizable to match your specific material, diameter, and process requirements. Backed by precision metrology and stringent quality control, it offers a cost-effective, high-reliability solution for modern wire drawing challenges.
