Closed die steel forging technical data and secondary operations
| Hot die forging tolerance thumb rule (not for precision forging) | < 0.8″ in die open direction, +/- 0.02″ > 0.8″ in die open direction, +/- 0.03″ The larger part, the looser tolerance; also depends on the part shape. |
|---|---|
| Part weight range | 0.2 to 44 lbs for die forging 44 lbs up for open die forging |
| Die draft | 5 – 7 degrees |
| Wall thickness range | Less than 4″ |
| Tooling construction | All molds are constructed from Premium H-13 or 30Cr tool steel and are heat treated to 50Rc or higher. Tooling is produced in-house, or out-sourced. |
| Die lifetime | 5K – 20K shots per tooling maintenance |
| Deburring | belt sanding, grinding machines, brush deburring, filing, sand blast, tumbling, vibration deburring, etc. |
| Die forging surface roughness (RMS, µin) | 125-63 |
| Normal lead time | Tooling and sample: 2 weeks – 3 weeks. Complicated parts take longer. |
| Secondary operations |

Engineering assistance
- CAD model development from your sample;
- Stress analysis, which helps in knowing whether the design is adequate and optimized, and what changes are needed before the physical part is made;
- Some Mechanical and Chemical Lab tests for your prototype part.
