Nut Forming Dies are precision tools used in cold heading or hot forging processes to shape metal wire (carbon steel, stainless steel, alloy steel, etc.) into standard or custom nuts, such as hex nuts, flange nuts, nylon lock nuts, and more. At XILUO Mold, our dies are engineered for exceptional dimensional accuracy, surface finish, and durability, ensuring high-volume production efficiency for industries like automotive, construction, machinery, and electronics.
Type | Carbide Nut Dies | HSS (High-Speed Steel) Dies | XILUO Advantage |
Key Features | Extreme wear resistance, ideal for high-volume production | Cost-effective, balanced toughness for medium batches | Material Sourcing: We use imported carbide (e.g., YG15, YG20) and premium HSS grades (e.g., SKH-51). |
Best For | Automotive-grade nuts, hardened steel nuts | Standard hex nuts, general-purpose fasteners | Custom Solutions: We recommend carbide for >500K cycles or HSS for budget-friendly projects. |
Surface Treatment | Titanium coating (TiN), nitriding | Precision polishing, oxidation resistance | Enhanced Durability: 20+ surface treatments to reduce friction and extend die lifespan by 30-50%. |
Type | Single-Station Dies | Multi-Station Dies | XILUO Advantage |
Design | Simple structure for basic nut shapes | Integrated multi-step forming for complex nuts (e.g., flanged, lock nuts) | Innovative Engineering: Patented multi-station designs ensure seamless transitions between forming stages. |
Efficiency | Fast setup, ideal for small batches | High-speed production with ±0.005mm tolerance | Speed-to-Market: 7-day lead time for standard dies; 15 days for fully custom designs. |
Applications | M6-M24 hex nuts, standard DIN/ISO nuts | Automotive lock nuts, flanged nuts, non-standard threads | Complex Geometry Expertise: We specialize in dies for asymmetrical or thin-walled nuts. |
China’s only integrated manufacturer with in-house R&D, material selection, production, and testing.
50+ countries served, with dies lasting 2-3x longer than industry averages.
