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
  • Heat treatment
  • Magnetic Crack Detection
  • Machining
  • Zinc plating
  • Nickel plating
  • E-coating

Engineering: Based on request, IQE can provide the following services for our customers:
  • 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.
