1. Hard Alloy Base Material, High Toughness
- Solid tungsten carbide substrate, high hardness & impact resistance
- Not easy to crack or break under high-speed fastener cold heading stamping
- Stable performance for mass bolt & nut continuous production
2. Premium TiN Titanium Coating Surface
- Uniform black titanium coating, ultra-low friction coefficient
- Anti-adhesion, prevent metal material sticking during punching
- Excellent oxidation resistance, extend service life greatly
3. Precision Square Molding Design
- High precision four-square forming head, strict dimensional tolerance ±0.002mm
- Smooth polished square surface, neat fastener product molding without burrs
- Uniform force bearing, reduce mold deflection and product deformation
4. Outstanding Wear & Corrosion Resistance
- Ti coating improves surface hardness, effectively reduce abrasion loss
- Resist high temperature generated by long-time punching work
- Lower mold maintenance frequency, save production cost
5. Custom Non-Standard Processing Available
- Custom length, square size, shank diameter, thread hole per your drawing
- Support small batch samples & large bulk orders for fastener manufacturers
- OEM & ODM service for all kinds of cold heading die punch tools
6. Strict Full Inspection Before Shipment
- 100% test concentricity, surface roughness, coating thickness and dimensional accuracy
- Consistent batch quality, no size deviation affecting fastener forming precision
