Wire drawing machines for 0.05mm to 0.25mm

For drawing heat-resistant wire in the 0.05mm to 0.25mm range, the following types of wire drawing machines are commonly used:

1. Fine Wire Drawing Machine

• Suitable for 0.1mm – 0.25mm wire diameter.

• Uses tungsten carbide or polycrystalline diamond (PCD) dies for high precision.

• Multi-pass system (typically 10–24 dies) for gradual diameter reduction.

• Equipped with cooling and lubrication systems to prevent wire breakage.

2. Ultra-Fine Wire Drawing Machine

• Designed for 0.01mm – 0.1mm ultra-fine wires, including 0.05mm wires.

• Uses natural diamond or PCD dies for ultra-smooth surfaces.

• Works at high speeds (1000–3000 m/min) with tension control.

• Often operates in a cleanroom environment for high-precision applications.

3. Multi-Pass Dry Drawing Machine

• Used for Fe-Cr-Al and Ni-Cr resistance wires.

• Multiple stages with gradually reducing dies to avoid excessive stress.

• Air-cooling or oil-lubrication systems for temperature control.

• Suitable for high-strength alloys where wet drawing is not ideal.

4. Wet Wire Drawing Machine

• Suitable for drawing nickel-based resistance wires and fine stainless steel wires.

• Uses water- or oil-based lubricants to reduce friction and enhance die life.

• Provides a smoother surface finish for high-performance applications.

5. Continuous Annealing Fine Wire Drawing Machine (For Heat-Treated Wires)

• Integrates drawing + in-line annealing, reducing oxidation risks.

• Commonly used for Ni-Cr and Cu-Ni resistance wires requiring soft annealing.

• Ensures consistent mechanical and electrical properties.

Key Considerations for Choosing a Machine:

✅ Material Type – Different alloys require different die materials (PCD, diamond, carbide).
✅ Wire Surface Quality – Ultra-fine wire applications need wet drawing or electro-polishing.
✅ Speed & Efficiency – High-speed machines are essential for mass production.
✅ Lubrication & Cooling – Crucial for preventing wire breakage at fine diameters.
