Sheet metal and metal forming inspection
Laser cutting, bending, stamping and deep drawing produce high volumes quickly. Small process drifts produce large numbers of rejects just as quickly.
01Small parts, large volumes, tight assemblies
Sheet metal parts are used in enclosures, machinery, vehicles, appliances and construction products. Typical quality issues are dimensional (bend angles, hole positions, flatness), surface related (scratches, burrs, coating defects) and joining related (spot welds, rivets, clinching).
QUALITAS TR inspects sheet metal parts and assemblies, audits stamping and fabrication processes and verifies first articles of new dies and bending programmes.
02Typical quality risks we see
- Bend angle and flange length variation
- Springback
- Burrs and sharp edges
- Hole position errors
- Flatness and twist
- Coating thickness and adhesion
- Spot weld strength
03How QUALITAS TR supports sheet metal and metal forming buyers
| Service | What we do in this sector |
|---|---|
| First Article Inspection | First article of new dies and bending programmes. |
| Independent Quality Control | In-process and final dimensional and visual control. |
| Manufacturing and Special Process Audits | Stamping, bending and coating process audits. |

04Key inspection points
- Material thickness and grade
- Flat pattern and hole positions
- Bend angles and flange lengths
- Flatness
- Burr height
- Spot weld tests
- Coating thickness and appearance
- Packing protection
05Standards and requirements
General tolerances for sheet metal parts often refer to ISO 2768 or company standards. Coating inspection follows the coating specification.
06The sector in Turkey
Sheet metal and stamping suppliers are concentrated around the automotive and appliance clusters in Bursa, Kocaeli, Sakarya, Manisa, Tekirdağ and İstanbul.
