Inside our quality control process
Every part passes dimensional inspection, material verification and a final visual check before it ships.

Key takeaways
- Dimensional inspection against the drawing.
- Material verification against the specified grade.
- A final visual check before dispatch.
Suits
Buyers of repeat batches and fit-critical parts who want to know what is checked before dispatch.
Worth knowing
Tell us which dimensions are critical at quote stage so inspection covers them.
The three checks
| Check | What it covers |
|---|---|
| Dimensional inspection | Each part is measured against the drawing before release |
| Material verification | Material is checked against the specified grade for the part's duty |
| Final visual check | A last pass confirms the part is ready to ship |
Recent batch work
| Job | Detail |
|---|---|
| Fifth production batch, UK electronics company | End-use components with threaded inserts for PCB mounting |
| Swiss engineering company | 5,700 parts in a 14-day lead time |
| Magtec (UK) | 500+ components for electric truck battery casings, third project together |
Reorders run from the same set-up so each batch matches the last. Customers working to tight tolerances can agree the critical dimensions and inspection method at quote stage. See our quality control page for the full process.
Inspection method by part type
| Part | Inspection |
|---|---|
| Simple features and holes | Callipers or micrometers |
| Complex geometry | CMM or 3D scanner |
| Repeat production batches | Same method each batch |

Frequently asked questions
What do you check before dispatch?
Dimensions against the drawing, material against the specified grade, and a final visual check.
Can I agree the critical dimensions?
Yes. Agree critical dimensions and the inspection method at quote stage.
How do you keep repeat batches consistent?
Reorders run from the same set-up, so each batch matches the last.
How are tight tolerances handled?
Where a tolerance is tighter than the process holds, we print the part and then ream or machine the critical feature.
