  • 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 degree
    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 assistance

    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.
