Service overview
Turn physical sample evidence into controlled manufacturing data.
Reverse engineering supports replacement, redesign, supplier transition, and documentation projects when usable CAD or drawings are incomplete. The work may combine manual measurement, 3D scanning, feature analysis, CAD rebuilding, and drawing preparation.
A scan captures surface shape but does not automatically define design intent. Functional datums, fits, nominal geometry, wear, damage, material, finish, and mating interfaces must be interpreted before a manufacturable model is released.
Multi-angle CAD reconstruction and dimensional verification using captured sample geometry.
Key capabilities
Process planning connected to the drawing and end use.
The manufacturing route is reviewed around geometry, material behavior, critical features, appearance, inspection, and downstream assembly.
Dimensional capture and 3D scanning
CAD reconstruction
Manufacturing drawing preparation
Typical parts
Parts commonly reviewed for reverse engineering.
Replacement housings
Machine components
Legacy brackets
Covers and guards
Jigs and fixtures
Cast or molded bodies
Mating interfaces
Redesigned assemblies
Industries
Applications supported across engineering teams.
Surface Finishes
Surface Finishes reviewed for material and application fit.
Tolerances and design guidance
Define what is functionally critical.
The achievable accuracy of reconstructed data depends on sample condition, access, surface reflectivity, measurement method, scan resolution, datum interpretation, and whether worn or damaged geometry must be restored to nominal intent.
DG 01
Provide the physical sample, mating parts, and known functional requirements where possible.
DG 02
Identify worn, damaged, or intentionally modified areas.
DG 03
Define the required deliverable: scan mesh, solid model, drawing, or manufacturing-ready package.
DG 04
Approve reconstructed datums and critical interfaces before manufacturing release.
Quality assurance
Inspection planning starts with the drawing.
Inspection points are selected from the controlled drawing, functional risk, process behavior, appearance criteria, and documentation requested for the project.
Sample identity and condition record
Measurement and scan coverage review
CAD-to-sample comparison
Drawing, revision, and manufacturing-readiness check

Manufacturing workflow
A controlled route from RFQ to shipment.
The exact route changes with process and project risk, but each stage keeps the approved drawings and requirements in view.
- 01
Sample and objective review
Record the part condition, intended use, known interfaces, and deliverables.
- 02
Dimensional capture
Use appropriate manual measurement or scanning for accessible geometry.
- 03
CAD reconstruction
Rebuild nominal features, datums, and design intent with comparison checks.
- 04
Approval and manufacturing review
Confirm data, prepare drawings, and review the selected production process.

Reverse Engineering questions from engineering and sourcing teams.
What should I provide for a reverse engineering quotation?
Send a 3D CAD file when available, a 2D drawing for critical dimensions and tolerances, material, quantity, finish, inspection, and delivery requirements. An engineer reviews the package before quotation.
Can Kewei work from a physical sample without CAD?
Yes. Share clear photos, overall size, sample condition, application, mating parts, material information, required quantity, and the physical sample when practical so the capture approach can be reviewed.
Does a 3D scan produce a manufacturing-ready model automatically?
No. Scan data normally requires cleanup, alignment, feature interpretation, nominal-geometry reconstruction, and drawing review before it becomes controlled manufacturing data.
How is lead time determined?
Lead time depends on geometry, material availability, quantity, tooling or setup requirements, surface finishing, inspection, and delivery needs. Timing is reviewed with the quotation rather than presented as a fixed promise.
