Our wire drawing dies are engineered for manufacturers who require precise diameter control, consistent surface finish, and extended die life. We supply a full range of PCD, carbide, natural diamond, single crystal, nano-coated, and shaped wire drawing dies to meet different production requirements.
These dies are widely used in the production of copper wire, aluminum wire, steel wire, alloy wire, and specialty materials, supporting industries such as electrical cable manufacturing, automotive components, electronics, and industrial wire processing.
With advanced manufacturing technology and strict quality inspection, we ensure stable performance in both high-speed and precision wire drawing applications.
We cover Φ0.012–Φ40.0 with annual capacity up to 2,000,000 pieces. Japanese molding, fiber laser drilling, and ultrasonic polishing support mirror finishes and stable geometry. Proven outcomes include diamond dies with 100–150× the wear resistance of carbide, die life up to 35 tons per piece under suitable conditions, bore enlargement control ≤0.8 μm, and surface roughness as low as Ra 0.03 μm. Strict QC and metrology (e.g., CU10, CU4) underpin batch consistency.
Choose the material that matches wire type, target diameter, speed, and budget.
| Material | Best for | Key benefits | Trade‑offs |
|---|---|---|---|
| PCD | Copper, aluminum; high‑speed multi‑pass | High wear resistance; stable finish | Not ideal for the ultra‑finest sizes |
| Natural / Single diamond | Ultra‑fine precision | Top surface quality; tight tolerance | Higher cost; supply considerations |
| Tungsten carbide | Steel; heavy gauge; abrasive alloys | Toughness; re‑polishable | Lower wear resistance than diamond |
| Nano‑coated carbide (CVD/PVD) | Budget‑sensitive high‑speed lines | Lower friction; extended life vs. plain carbide | Not diamond‑level life or finish |
PCD (Polycrystalline Diamond) dies are the non‑ferrous workhorse. They deliver long, consistent runs in copper and aluminum at high speeds. Compared with carbide, they maintain geometry through multi‑pass reductions and offer excellent cost‑to‑life. PCD drawing dies are ideal for high-speed and large-volume production. They offer excellent wear resistance and long service life, making them suitable for non-ferrous wires such as copper and aluminum.
Natural diamond dies are designed for ultra-fine wire drawing and high surface quality requirements. They deliver superior precision and are commonly used in fine wire and micro-wire production.
Carbide suits larger diameters, steel, and abrasive alloys. Common grades include YG8, YG6X, GK05A, and GU10. Add CVD or PVD coatings to reduce friction and extend service.
Nano-coated dies enhance surface hardness and wear resistance, helping to improve die lifespan and maintain consistent performance under demanding conditions.
| Parameter | Capability |
|---|---|
| Working diameter range | Φ0.012–Φ40.0 |
| Bearing length tolerance | ±1 μm |
| Compression angle tolerance | ±0.5° |
| Bore enlargement control | ≤0.8 μm over long runs |
Profile and surface are tuned to minimize friction and heat, preserving roundness and finish.
