Shaping metal by compressive force for superior strength
| Type | Temp (Steel) | Tolerance | Strength vs Machined |
|---|---|---|---|
| Hot Forging | 900-1250C | +-1mm | +15-25% |
| Warm Forging | 600-900C | +-0.3mm | +20-30% |
| Cold Forging | Room temp | +-0.05mm | +30-50% |
Draft angles: 3-7 deg (hot), 0-3 deg (cold). Min radius: 3mm hot, 1mm cold. Max section change: 3:1 per step.
