Cold Heading Die Blanks / Fastener Blanks

Tungsten steel cold heading dies are precision-engineered tools crafted from tungsten carbide, a material known for its outstanding hardness, wear resistance, and durability. These dies are essential in the cold heading process, shaping fasteners such as screws, bolts, and rivets with high accuracy and efficiency.

Key Features

1. Exceptional Hardness
   • Made from tungsten carbide with a hardness rating of HRA 85–92, these dies maintain their integrity under extreme pressures.
2. High Wear Resistance
   • Superior material composition ensures extended wear life, even in high-volume production environments.
3. Impact Resistance
   • The optimized tungsten-cobalt ratio (e.g., 85:15) provides excellent resistance to cracking or deformation under sudden forces.
4. Thermal Stability
   • With excellent heat resistance, the dies perform reliably in high-friction, high-temperature applications.
5. Precision Machining
   • Produced using advanced machining techniques, ensuring dimensional accuracy and consistent performance.

Applications

• Fastener Manufacturing
  Designed for producing screws, bolts, nuts, and rivets from materials such as stainless steel, carbon steel, and alloys.
• Cold Forming Processes
  Suitable for high-precision cold forming of various metal components requiring superior strength and accuracy.
• High-Volume Production
  Ideal for industries that demand long-lasting tools with minimal downtime and high output rates.

Technical Specifications

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

Benefits

1. Cost Efficiency
   • Reduces tool replacement frequency and overall production costs.
2. Enhanced Product Quality
   • Ensures precise shaping, minimizing defects and improving final product consistency.
3. Versatility
   • Suitable for various cold heading applications and adaptable for customized designs.
