Your sheet metal parts,
from the tool to the series
Blanking, bending, deep drawing, progressive dies — for your metal parts in medium and large series. A single point of contact, a network of stamping shops sourced and controlled in France, and full tooling coordination.
In stamping, the tool commits you — the right choice is made beforehand
The tool (punch + die) is expensive and locks your part for years. Choosing the right process, the right sheet grade and the right workshop from the start means avoiding a failed tool and too-high a part price. CadNov secures this decision.

OUR EXPERTISE
Integrator: your tooling steered, from design to inspection
Formability analysis and design advice
Workshop and press selection by series
We are not an in-house stamper — we are your integrator: feasibility study, tool design/sourcing, workshop selection, follow-up and inspection in France. You keep a single point of contact for the whole chain.
- Associated operations: welding, tapping, insertion, finishing
- Coordination of treatments and coatings
- Receiving inspection in France, traceability, reports
- Straight talk: stamping is only cost-effective in series (the tool amortizes). For small quantities or sheet-metal prototypes, laser + bending is often more economical — we tell you and steer you, rather than sell you a pointless tool.

TOOLING
The tool's cost and lead time are the real subject. We factor them in from the break-even calculation.
Series
Tool cost
Simple tool / one operation
small to medium
moderate
large
| high | very high | large, large parts | Metal spinning (no dedicated tool) |
|---|---|---|---|
| proto / small | very low | MATERIALS | Common thicknesses from 0.3 to 6 mm depending on the press and part (to confirm by workshop). |
| TOOLING | Drawing steels | Coated steels | Stainless steel |
| Series | Aluminum | Coated steels | Brass · Copper |
| HSLA / high-strength | HSLA steels for structural weight reduction (springback to manage). | TOLERANCES AND INSPECTION | MATERIALS |
Springback compensated on the tool
Flatness and no folds / sink marks, controlled
Repeatability across large series
Dimensional inspection, fixtures, SPC in series
Tool validation: initial samples (ISIR / PPAP)

Guide value
Bending / simple shape
DC01 · alu 5754
Medium drawing
- DC03 / DC04
- common hollow parts
- Deep / complex drawing
- DC05 / DC06 (IF)
high deformation, non-aging
- Exterior / corrosion protection from the material
- DX51D galvanized, pre-painted
- protected without re-treatment
- Formed stainless (food, medical)

Light / conductive
| alu 1050, copper, brass | weight reduction, thermal / electrical | Deep drawing: beyond a certain height/diameter ratio, the part is made in several passes, sometimes with an intermediate anneal to restore ductility. It's the only truly useful heat treatment here. |
|---|---|---|
| Need | Solution | Substrate |
| Good to know | Corrosion protection from the material | Galvanized (DX51D) / pre-painted sheet |
| steel | protect cuts and welds | Corrosion protection after forming |
| Zinc plating / zinc-nickel | finished part | Appearance / color |
| Paint, powder coating | steel, aluminum | any RAL |
| Stainless: appearance + corrosion | Passivation, brushing, polishing | stainless |
no zinc plating on stainless
| Aluminum: hardness / deco | Anodizing | aluminum | — |
|---|---|---|---|
| Contact / solderability | Tin plating, nickel plating | steel, brass, copper | sheet-metal connectors |
| Pre-coated sheet: stamping can mark or crack the coating on heavy deformations. Depending on the requirement, we stamp then treat, or we touch up the reworked areas (cuts, welds). | DESIGN TIPS | steel, brass, copper | Generous radii |
| Manage springback | Volume = process | Optimize the blank | Right grade |
| Realistic tolerances | Sheet metal has its limits: functional dimensions only. | INSPECTION AND ESG APPROACH | Inspected in France, committed ESG approach |
| Inspection in France | Receipt and check of parts in France before shipping. Real and verifiable. | Workshop selection | Technical qualification, capacity, quality: known, monitored partners. |
| ESG being rolled out | Environmental and social criteria being integrated — an approach, not an acquired label. | LARGE SERIES | Volume-based discounts, planned tool amortization |
