Precision Wire Drawing Dies
From the hardest synthetic diamonds to robust carbide, we engineer the optimal reduction zone for every ferrous and non-ferrous application.
Material Selection Strategy
Choosing the right die material is a balance between wear resistance, surface finish requirements, and impact strength. Titan Precision offers the full spectrum of core materials to match your specific wire drawing process.
Our engineering team analyzes your incoming rod quality, reduction ratios, and final application to recommend the perfect grade:
-
PCD (Polycrystalline Diamond) For maximum life (20-50x Carbide). Best for hard, abrasive wires like Stainless Steel, Titanium, and Nickel Alloys.
-
ND (Natural Diamond) For superior surface finish. Essential for fine magnet wire, medical wire, and precious metals where Ra < 0.02μm is required.
-
TC (Tungsten Carbide) For impact resistance and economy. Ideal for rod breakdown, large diameters, and short custom runs.
Technical Specifications
Diameter Range
ND/MCD: 0.01mm - 1.3mm
PCD: 0.05mm - 8.0mm
TC: 0.05mm - 35mm
Geometry Control
Reduction angles controlled to ±0.5°. Bearing lengths customizable from 10% to 100% of diameter.
Casing Options
Standard stainless steel casings or high-thermal-conductivity sintered bronze mounts.
"We use Titan's PCD dies for our intermediate draw and their ND dies for the final finishing pass. The combination gives us both long life and a perfect surface."
