Reverse Engineering of Forged Parts
Obsolete machines, discontinued spares and imported components with no available drawing are an everyday problem in Indian industry. We take the physical sample, measure it, identify the material and produce a manufacturable drawing and a forged replacement.

Measure, Identify, Model
The sample is dimensioned feature by feature, hardness tested and spectro analysed to establish the actual grade rather than a guess. Wear is compensated by referencing mating dimensions, and the reconstructed geometry is modelled in 3D and issued as a drawing for your approval.

Improving on the Original
Reverse engineering is a chance to correct the reason the part failed. A stress-raising sharp corner becomes a proper fillet; a machined-from-bar part becomes a forging with grain flow along the load path; a marginal grade is upgraded to one with better fatigue performance.
Typical Turnaround
Drawing and material report within five to seven working days of receiving the sample. Forged samples follow the standard die lead time, or immediately on the open die line for one-off replacements where no die is justified.
What We Capture From a Sample
A physical part carries more information than its dimensions. Reproducing it accurately means recovering the material and its condition as well as the geometry, because a replacement with correct dimensions and the wrong grade will fail in service while looking perfect on inspection.
| What is captured | How | Why it matters |
|---|---|---|
| Chemical composition | Optical emission spectrometry | Identifies the actual grade, not a guess |
| Hardness | Brinell or Rockwell, several locations | Reveals the heat treatment condition |
| Case depth | Microhardness traverse on a section | Shows whether the surface was hardened |
| Microstructure | Etched sample under microscope | Confirms treatment and reveals defects |
| Grain flow | Macroetch | Shows whether the original was forged |
| Geometry | Dimensional measurement, feature by feature | Reconstructs the drawing |
| Wear | Comparison with mating parts | Allows worn dimensions to be corrected |
Compensating for Wear on a Used Sample
Most samples arrive worn, sometimes badly. Wear is compensated by referencing the mating component's dimensions and by measuring unworn areas of the same feature. Where the mating part can also be supplied, fit is verified directly rather than estimated — which is why we ask for it whenever a replacement has to go back into an existing assembly. On a failed part, the fracture surface is examined before anything else, because reproducing a part that failed by design repeats the failure.
Improving on the Original
A worn or broken part is evidence about its own weaknesses. Reverse engineering is the natural moment to correct them: a sharp corner that started a crack becomes a proper fillet, a component machined from bar becomes a forging with grain following the load path, a marginal grade is upgraded to one with better fatigue behaviour. We propose such changes with the reasoning and leave the decision to you, then issue a drawing for approval before any tooling or material is committed. Typical turnaround for drawing and material report is five to seven working days.
- Drawing and material report in 5 – 7 working days
- Single pieces via open die forging; production via closed die
- The drawing is issued to you and is yours to use

A drawing and material report within five to seven working days of receiving the sample.
Do I own the drawing you create from my sample?
Yes. The drawing is issued to you and can be used elsewhere; customer parts and drawings are treated as confidential.

Questions Answered
Can you make a part with no drawing at all?
+
Yes. A physical sample is enough — we generate the drawing, and it is issued to you for approval before any tooling is cut.
How do you know which steel the original was?
+
Optical emission spectrometry gives the actual chemistry, and hardness plus microstructure confirm the heat treatment condition.
Will the replacement fit exactly?
+
We compensate for wear by referencing mating dimensions and, where possible, ask for the mating part or its dimensions to verify fit.
Is reverse engineering charged separately?
+
A nominal engineering charge applies, and it is typically adjusted against the production order.
