Multi-station cold-heading explained
COLD-HEADING — wire stock deformed at room temperature; 150-450 pieces/min, >95% material utilization, excellent dimensional accuracy. Best for high-volume bolts, screws, rivets. HOT FORGING — material heated then formed; works for harder materials and larger sizes; lower productivity. Best for large fasteners (M24+), high-tensile, specialty geometries. CNC MACHINING — turned/milled from bar stock; extreme flexibility but very low productivity (10-50 pieces/min), poor material utilization. Best for low-volume specialty/prototype. ECONOMICS: cold-headed bolt USD 0.02-0.05 each vs hot-forged USD 0.08-0.18 vs CNC USD 0.50-3.00. Production line investment higher for cold-heading but per-piece cost dramatically lower at high volume.

| 4-die 4-blow (4D4B) | Complex specialty/automotive fasteners — precision geometry |
| 5-die 5-blow (5D5B) | Precision automotive/aerospace fasteners — tight tolerances |
| 6-die 6-blow (6D6B) | Premium specialty fasteners — highest complexity |
