Applications

As the largest application field for wire drawing dies (accounting for 81% of global demand), dies are utilized to draw copper, aluminum, and other metal wires from coarse to fine diameters (e.g., Φ0.013mm–16mm). This ensures optimal conductivity, mechanical strength, and surface smoothness of cables. Carbide and PCD (polycrystalline diamond) dies dominate this sector due to exceptional wear resistance, particularly in high-speed drawing machines (>30m/s) where continuous production stability is critical.

Ferrous & Alloy Wires: Carbide dies (e.g., YG8/YG6X grades) produce steel wires, stainless steel wires, and molybdenum wires for construction steel cords, welding wires, and cutting wires. Example:

Electronics & Semiconductors: Diamond dies (natural/PCD) draw micron-level wires (Φ<0.1mm), such as tungsten-molybdenum wires for electronic components and bonding wires for chip packaging. Surface roughness ≤0.05μm meets ultra-precision requirements.

 Aerospace & Medical: CVD-coated dies enable stable forming of hard-to-process materials (titanium alloys, superalloys), leveraging heat resistance (950°C) and corrosion resistance for aerospace fasteners and medical implant wires.

 Fiber Optics: Carbide dies ensure diameter precision and surface integrity during optical fiber drawing, directly impacting light signal transmission efficiency.

 Jewelry: Natural diamond dies craft gold, silver, and platinum wires with scratch-free surfaces and high gloss, supporting complex cross-sections.

 Industrial Components: Shaped dies (square, semi-circular holes, etc.) produce flat wires for piston rings and alloy wires for zipper teeth, replacing multi-step processes and boosting efficiency by 130%.

Drawing dies manufacture prestressed steel wires and steel strands for construction. Carbide dies excel in large-diameter wire (>Φ8mm) mass production due to high impact resistance (bending strength: 2,300N/mm²).
