High Precision Tungsten Carbide Cold Heading Dies for Screw Bolt Fastener Manufacturing | Long Life Cycle Custom Tooling
Product Overview:
We specialize in high-performance Cold Heading Dies (CHD) engineered for the mass production of bolts, screws, and rivets. Using premium grade Tungsten Carbide (G5/G6/EA90/ST7), our dies are designed to withstand extreme pressure and high-speed impacts in multi-station cold heading machines.
Key Technical Specifications:
- Material: Tungsten Carbide Insert (Cobalt 10%-25%) + Steel Casing (H13/SKD61)
- Tolerance: Within ±0.005mm (High Precision Grinding)
- Hardness: HRA 86-91 (Optimized for wear resistance)
- Surface Finish: Mirror Polishing (Ra 0.05) to prevent material sticking
- Life Cycle: 500,000 – 1,000,000+ pieces (Depending on wire material)
Why Choose Our Cold Heading Dies?
- Extended Tool Life: Our heat-treatment process ensures a perfect bond between the carbide insert and the steel case, preventing cracking during high-speed production.
- Superior Material Quality: We use only Virgin Tungsten Carbide powder, ensuring zero porosity and maximum fracture toughness.
- Fast Customization: Send us your fastener drawings (DIN/ISO/ANSI) or wire samples, and our engineers will provide a technical drawing for approval within 24 hours.
- Compatible with Major Brands: Our dies are fully compatible with National, Jern Yao, Chun Zu, and other high-speed heading machines.
Applications:
- Fasteners: Wood screws, drywall screws, self-tapping screws, hex bolts, rivets.
- Industries: Automotive, Aerospace, Electronics, and Construction.
