Specializing in cold extrusion processes, these dies shape high-strength materials (e.g., SPCC steel) into complex geometries without heat treatment. The process ensures enhanced mechanical properties (e.g., tensile strength ≥450MPa) and burr-free edges through precision tool alignment.

Cold Heading Dies for High-Strength Components
What Are Cold Heading Dies?
Cold heading dies are specialized tools used in cold forging processes to form metal wires into high-strength fasteners (bolts, screws, nuts) without heating. This process enhances material strength and durability while maintaining tight tolerances (±0.02mm).
Key Features
✔ High-Speed Production – Capable of 50,000+ units/day
✔ Material Versatility – Works with stainless steel, alloy steel, titanium
✔ Precision Tolerances – ±0.02mm for critical dimensions
✔ Extended Die Life – Made from premium tool steels (e.g., SKD11, SLD-Magic)
