Metal stamping is a precise and high-speed manufacturing process. But many buyers ask: What are the 7 steps in the stamping method? Understanding this sequence helps you plan better, manage lead times, and avoid costly redesigns.
Stamping involves material preparation, die setup, feeding, forming, cutting, ejection, and quality inspection. Each step contributes to consistency and efficiency.
In this article, we’ll walk through all 7 steps, while covering the most common stamping methods and their use in industries like automotive.

What Are the 7 Steps in Stamping Method?
Kevin (Buyer):
I know stamping is fast—but what exactly happens from start to finish? What are the 7 steps in the stamping method?
Leo (Engineer, Prime):
Great question. Whether you're stamping auto parts or appliance brackets, the core process follows seven key steps.
The 7 Key Steps of Metal Stamping:
| Step | Description |
|---|---|
| 1. Material Preparation | Choose and load sheet metal rolls or blanks. |
| 2. Die Setup | Install and align stamping dies into the press. |
| 3. Material Feeding | Use manual, servo, or coil feeders to insert metal. |
| 4. Forming & Cutting | Press activates dies to shape and cut the material. |
| 5. Part Ejection | Part is ejected or collected from the press area. |
| 6. Inspection | Visual or dimensional checks for quality control. |
| 7. Packaging | Parts are counted, packed, and moved to shipping. |
Leo:
At Prime, we automate most of these steps in our progressive die lines. That’s how we maintain speed, precision, and repeatability.
What Are the Methods of Stamping?
Kevin:
So is there just one stamping technique? Or are there different methods depending on the part?
Leo:
There are multiple methods of stamping, each suited to different part types, tolerances, and volume.
Common Stamping Methods:
| Method | Description |
|---|---|
| Progressive Die | Multiple actions in one press stroke (high volume) |
| Transfer Die | Separate dies; part is transferred station to station |
| Deep Draw Stamping | Used for forming cups, cases, and deep housings |
| Fine Blanking | High-precision stamping with smooth edge finishes |
| Compound Die | One stroke performs multiple functions on one part |
Leo:
Most of our auto industry clients use progressive die stamping, while electronics companies often choose fine blanking for clean edges.
What Is the Process of Stamping a Car?
Kevin:
Let’s get specific—what’s the stamping process in automotive manufacturing?
Leo:
Car stamping involves forming large metal sheets into body panels like doors, roofs, and fenders.
Automotive Stamping Process:
- Steel Coil Loading – Rolls of galvanized steel are prepared.
- Blanking – Sheets are cut into specific shapes.
- Lubrication – Sheets are oiled for friction control.
- Forming – Dies press the sheet into a panel (door, hood, etc.)
- Trimming – Edges are cut to the final contour.
- Piercing – Holes and slots are added.
- Inspection & Transfer – Panels move to the welding/assembly line.
Leo:
At Prime, we don’t stamp entire car bodies, but we do supply precision brackets, clips, and metal inserts used in the car interiors and structural frames.
What Is the Forming Process in Stamping?
Kevin:
Is forming the same as stamping?
Leo:
Not quite. Forming is a subset of stamping. It refers to bending, drawing, flanging, and other shape-changing operations—without removing material.
Common Forming Operations in Stamping:
| Forming Type | Purpose |
|---|---|
| Bending | Create angles or curves |
| Drawing | Pull metal into a deeper cavity |
| Coining | Apply compressive force to form surface features |
| Flanging | Turn sheet edge to a different angle |
| Embossing | Add logos, ribs, or patterns into the part |
Leo:
So if you ask "what is the forming process in stamping?"—it’s the part of stamping that reshapes without cutting.
FAQs
1. What materials can be stamped?
→ Steel, stainless steel, aluminum, brass, copper.
2. How fast is metal stamping?
→ Progressive lines can produce 100–1,000+ parts per minute.
3. What’s the minimum order for custom stamping?
→ At Prime, we accept orders starting from 5,000 units, depending on the part.
4. Can one die handle multiple part types?
→ Not typically. Each part requires a custom die unless minor variants are planned.
5. Do you provide inspection reports?
→ Yes. We offer full ISO 9001-certified QC documentation with every order.
