Tungsten steel cold heading dies are crafted from premium tungsten carbide materials, known for their exceptional hardness, wear resistance, and impact toughness. These dies are indispensable tools in cold heading processes, designed to meet the demands of high-strength and precision forming. They are widely used in manufacturing fasteners and metal components.

Key Features

1. High Hardness and Wear Resistance
   • Tungsten steel achieves a hardness of HRA 85–92, ensuring dimensional stability under high-pressure conditions.
2. Superior Impact Resistance
   • The optimized tungsten-cobalt ratio (e.g., 85:15) effectively prevents damage caused by the impact forces during cold heading.
3. Excellent Thermal Stability
   • Suitable for extended high-intensity use, resisting the effects of high frictional heat on performance.
4. Precision Machining
   • Manufactured with advanced equipment, offering tight dimensional tolerances and high surface finish for precision forming.

Applications

• Fastener Production
  Ideal for manufacturing screws, bolts, rivets, and similar fasteners made from stainless steel, carbon steel, and alloy steel.
• Metal Cold Forming
  Performs exceptionally in cold extrusion and stamping of metal components requiring high strength and accuracy.
• High-Efficiency Production
  Perfect for production lines demanding high durability and minimal downtime, significantly reducing maintenance frequency.

Technical Specifications

• Material Composition: Tungsten carbide (WC) with 5%–15% cobalt (Co) content
• Hardness: HRA 85–92
• Bending Strength: >3000 MPa
• Service Life: Up to 300,000 cycles (depending on operational conditions)

Advantages

1. Extended Tool Life
   • Reduces the frequency of replacements, lowering overall production costs.
2. Improved Product Quality
   • Enhances product consistency, reducing defect rates and waste.
3. Customization Support
   • Dimensions, material composition, and design can be tailored to meet specific production needs.
