What we do for castings and foundries
| Job | What you get |
|---|---|
| First casting from a new or repaired pattern | The scan compared with the casting CAD, so errors show before the full batch is poured |
| Patterns and core boxes | A check for wear, a damaged core print or a wrong allowance, against the CAD or a master |
| Rough castings before machining | The scan aligned to the finished-part CAD, so you see the stock left on each face |
| First-article and sample inspection | A PDF report: deviation colour map, dimensions and GD&T callouts |
| Rejected or disputed castings | The part measured against the CAD that was agreed, with a colour map both sides can read |
| Pattern or cast part with no CAD | A scan rebuilt as a clean STEP model your pattern shop can work from (see spare part with no drawing) |
| Worn cast wear parts | CAD of the part so a replacement can be made again |
Items we can scan: sand, die, investment and gravity castings, forgings, wooden or metal patterns, core boxes and cast wear parts. Our scanner maker lists automotive, rail, aerospace, energy, mould and machinery manufacturing among the industries the scanners are used in, so parts from these fields can be scanned.
How a casting job runs
- Brief. You send a photo, the approximate size and weight, the material and what you want: an inspection, CAD or both. Send the casting CAD and drawing if you have them.
- 3D scan. Handheld blue-laser scanning suits small to medium castings and patterns; optical-tracking scanning suits large castings and patterns. We scan at our Coimbatore facility or where the casting stands, so heavy items need not be moved. Very shiny machined faces can change the method, so tell us the surface.
- Mesh cleaning. The scan is merged, cleaned and checked for gaps. The mesh can be delivered as STL or PLY.
- Compare or rebuild. For inspection, the scan is aligned to your CAD and shown as a deviation colour map. For a part with no CAD, we rebuild the surfaces as clean, editable CAD from sections and features, not as a copy of the rough mesh. We do not promise a tolerance until we have seen the casting and its job.
- Report. Inspection reports are normally delivered in 2 to 3 days.
- Delivery. A PDF report, plus STEP (IGES or Parasolid on request) and the mesh if you want them.
Shrinkage allowance, gating and pattern design stay with your foundry or pattern shop. We supply the scan data, the CAD and the inspection report.
Scan, CMM arm or both
A cast surface rarely sits exactly where the drawing puts it. A 3D scan covers the whole casting, so a thin wall, core shift or parting-line mismatch shows in colour, not only at a few probe points. For datum-based features, bores and tight machined dimensions, a portable CMM arm is the better tool, and some checks suit both. See our CMM inspection services.
What decides the cost
We quote per job and do not publish a price list. The main drivers are:
- the size, weight and number of castings or patterns,
- how complex the shape is,
- the tolerance or allowance you work to,
- the output (a colour map is quicker than a full CAD model),
- on-site work, travel and accommodation.

Why scan first
A scanner captures the whole casting, including freeform surfaces that are hard to measure by hand, and shows variation across the surface instead of at a few points. The JINUOSH Vertex handheld blue-laser scanners we distribute are specified by the maker at up to 0.020 mm (Vertex3D and Vertex3D Pro) and 0.025 mm (Vertex Tracker). That is a scanner specification, not a guarantee for every casting; we tell you the expected accuracy for your part before we start. See the JINUOSH Vertex scanners.
Part of a wider service
This is one use of our 3D scanning services in India and reverse engineering services in India. For tools rather than castings, see mould and die 3D scanning. For vehicle parts, see automotive 3D scanning and reverse engineering. Wondering what it will cost? Read 3D scanning cost in India: what decides the quote. In Tamil Nadu? See reverse engineering in Tamil Nadu. In Coimbatore? See 3D scanning services in Coimbatore. Choosing a provider? Read how to choose a 3D scanning service, or compare JINUOSH Vertex with other scanner brands. Need a printed copy or fit-check of a scanned part? See 3D printing from your 3D scan. For how a scan becomes an editable model, read scan to CAD in SolidWorks. Not sure which file to ask for (STL, STEP, IGES, Parasolid or the PDF report)? Read what files you get from a 3D scan.
