Wire drawing dies (typically made of diamond or cemented carbide/tungsten steel) must meet the following special requirements:
- High Hardness: Tungsten wire is highly hard, so the die must be wear-resistant (e.g., natural or synthetic diamond).
- High Precision: Die aperture tolerance must be controlled at the micron level to ensure consistent tungsten wire diameter.
- Smooth Inner Surface: The die bore surface must be highly polished to reduce friction and minimize surface scratches on the tungsten wire.
- High Temperature Resistance: The die heats up due to friction during drawing and must withstand temperatures of several hundred degrees Celsius.
- Chemical Stability: Die materials must resist corrosion from lubricants or cleaning agents.
- Geometric Design: The die bore must have an appropriate cone angle (approximately 8–12°) and reduction zone length to optimize drawing force and prevent wire breakage.
