Description
Tungsten Carbide (TC/WC) Wire Drawing Dies
Industrial Applications
While ultra-hard diamond dies excel in fine-microwire applications, Uking’s premium cemented carbide (tungsten steel) dies deliver the most economical, high-tonnage solution for heavy-duty drawing pipelines, specifically optimized for:
Steel Wire Industry: High-carbon steel wire, structural steel lines, welding wires, and spring steel manufacturing.
Large-Diameter Cable Stranding: Drafting, bundling, and twisting of bulk power cables and infrastructure wiring grids.
Non-Ferrous Heavy Drafting : Large-size aluminum rods, copper bars, and diverse hard alloy tube or rod profiling.
High-Loss High-Impact Operations: Pre-drawing stages where initial wire surfaces are rough, uneven, or scale-heavy, acting as a crucial defense tool before precision diamond finishing.

Product Details
1. Premium Metallurgical Matrix & Optimized Cobalt Balance
Uking Diamond’s tungsten carbide (TC) drawing dies are manufactured utilizing sub-micron tungsten carbide particles seamlessly bonded in a highly optimized cobalt matrix. By strictly regulating the WC-to-Cobalt ratio, our metallurgical engineering ensures an optimal balance between exceptional wear resistance (hardness) and high fracture toughness.
Unlike generic tungsten steel modules on the market, our sintered compacts feature zero internal porosity, allowing the inner geometry to withstand intense radial pressures and extreme high-temperature environments up to 2800 °C without mechanical deformation.
2. The Ideal Economical Alternative for Structural High-Loss Lines
In multi-stage industrial wire drawing, using expensive PCD or ND dies for initial large-diameter or abrasive high-carbon steel wire drawing can be financially non-viable.
Uking’s cemented carbide dies provide a heavy-duty, low-cost operating framework. Featuring low energy consumption and an exceptionally low coefficient of friction under standard powder/dry lubricants, these dies handle highly abrasive metal processing with prolonged continuous stability, ensuring a predictable tool-change schedule and significantly lowering the cost per ton of finished metal.
Key Features
Extreme Shock & Impact Resistance: The robust cobalt-bonded cement matrix effortlessly absorbs sudden load spikes and vibrations common in high-speed steel cable twisting and structural wire drawing.
Massive Diameter Capabilities (Up to 45mm): Precision-engineered core geometries across the entire 0.1mm to 45mm spectrum, accommodating massive industrial conductors and heavy alloy tubing.
Outstanding Corrosion & Wear Immunity: High chemical inertness resists acidic or alkaline additives within generic heavy drawing lubricants, avoiding premature chemical erosion and scaling.
Advanced Internal Mirror Polish: Every die hole undergoes rigorous diamond-slurry finish polishing, achieving an ultra-smooth profile that minimizes metal shaving buildup and guarantees a clean surface on bulk conductors.
