Tungsten Carbide Wire Drawing Dies for Precision Wire Manufacturing

Material Composition:

Tungsten Carbide (WC) Matrix (85-94%): Provides the primary hardness and wear characteristics
Cobalt Binder (6-15%): Enhances toughness and impact resistance
Optional Additives: May include grain growth inhibitors for improved performance

Common Applications:
Electrical wire and cable production (copper, aluminum)
Steel cord manufacturing for tires
Precision wire for medical devices
Fastener and spring wire production
Specialty wire for welding and electronics
Technical Specifications:
Diameter Range: 0.01mm to 30mm
Tolerance: ±0.001mm to ±0.005mm
Surface Finish: Up to 0.05μm mirror finish available
Working Life: Typically 3-5 times longer than tool steel dies
Types of Tungsten Carbide Dies:
Single Crystal Carbide Dies: For ultra-fine wire drawing
Polycrystalline Carbide Dies: General purpose applications
Composite Carbide Dies: With special wear-resistant layers
Steel-Encased Carbide Dies: For high-pressure applications

Advantages Over Alternatives:
Compared to Steel Dies: 5-10x longer service life
Compared to Diamond Dies: More cost-effective for medium wire sizes
Compared to Ceramic Dies: Better mechanical strength and thermal conductivity

Selection Considerations:
Wire material (copper, steel, aluminum, etc.)
Required reduction ratio
Drawing speed requirements
Surface finish specifications
Production volume expectations

Maintenance Tips:

Regular cleaning with ultrasonic cleaners
Proper lubrication during operation
Periodic inspection of die geometry
Proper storage in dry conditions
