Toyota Corolla KE72 rear brake light bracket
Reverse engineeringA discontinued bracket for a classic Corolla, rebuilt from the broken original.
Service
Reverse Engineering Services in Sri Lanka
A part that is no longer sold, rebuilt from the one you still have.
When a component is discontinued, the usual options are a used part of unknown condition, an assembly you do not need, or nothing at all. Reverse engineering removes that dead end: the part you have becomes a measured model, and the model becomes a part you can order again.
The work starts with the physical component, however damaged. It is measured and scanned, rebuilt as a solid CAD model, and then checked back against the original and its mating parts before anything is manufactured. Cracks, missing corners and worn faces are reconstructed to the geometry the part had when it was new — not copied as-is.
This is the service behind most of the automotive work in our portfolio, from a Toyota Corolla KE72 brake light bracket to a Jaguar XJ sunroof positioning clip. It applies just as directly to industrial parts, where an obsolete component can hold up a whole production line.
What you receive
- Solid CAD model of the part
- CAD-ready files: STEP, STL, IGES
- Manufactured replacement part
- Fit verification against the original
Suited to
- Classic and imported vehicles with no parts supply
- Machines whose spares are obsolete
- Parts only sold as part of a much larger assembly
- Components that keep failing and need a stronger redesign
Coverage
Colombo and surrounding areas, with island-wide delivery and on-site engineering support.

How the work runs
Starts with the physical part, however damaged, and ends with a manufactured replacement.
- 01
Capture the original
The part is scanned, and hand-measured wherever a datum matters more than a surface.
To 0.02 mm
- 02
Align to datums
The scan is oriented to real reference planes and axes, not whatever angle it was captured at.
- 03
Rebuild as CAD
Features are rebuilt parametrically in SolidWorks from the scan — not traced over the mesh as a fixed shape.
SolidWorks
- 04
Reconstruct what's missing
Cracks, worn faces and broken corners are rebuilt to the geometry the part had when it was new.
- 05
Deviation analysis
The rebuilt model is overlaid on the captured scan and checked point by point, so any drift from the real geometry is caught and corrected before the model is treated as finished.
- 06
Verify fit
Checked against the mating parts and the assembly it belongs to, before anything is manufactured.
- 07
Manufacture or hand over the files
3D printed, laser cut, or supplied as STEP, STL and IGES for your own manufacturer.

Common questions
Before you ask
- Can you remake a spare part for an old car that is no longer available in Sri Lanka?
- Yes — that is most of what we do. Bring the original, even in pieces. We scan it, rebuild it as a CAD model, and manufacture a replacement that fits and works like the real part. The model stays on file, so a second one later is a reprint rather than a fresh job.
- My vehicle is discontinued and the agent has no stock. What are my options?
- Send us the part, or whatever is left of it. Reverse engineering exists exactly for this case — no drawing, no supplier, just the worn or broken component. We tell you honestly whether the geometry that survives is enough to rebuild from.
- Can you rebuild a part that is broken or missing pieces?
- Yes — that is the normal case. As long as enough of the original geometry survives to establish the mating faces and fixing points, the missing sections can be reconstructed in CAD. Bring every fragment you still have; more evidence means less interpretation.
- What if I do not have the part at all?
- It is still possible, but it becomes design rather than reverse engineering. We would work from the mating parts, the cavity the component sits in, photographs, and any drawings or dimensions you can supply. Say so up front, because it changes the scope.
- Will the replacement be as strong as the original?
- It depends on the part and the material chosen for it. A bracket, cover, clip or housing can generally be made to perform like the original, and geometry can be reinforced where the original was known to fail. Tell us the load case and operating temperature and we will tell you honestly whether the process suits it.
- How long does reverse engineering take?
- It depends on the geometry and how much of the original survives. Send photographs and the overall dimensions and we will give you a realistic timeline with the quote rather than a generic one.
Bring us the problem.
A part, a process, or just an idea. Tell us the situation and we will tell you the engineering route to solving it — honestly, even if that route isn't us.
