Six Core Stamping Operations

Each operation creates a different feature. Several may be combined within the tooling needed for one finished component.

1. Blanking

   Cuts the outside profile to produce a blank for the part or a later forming step.

2. Piercing & Punching

   Creates internal holes, slots and cutouts, including mounting or ventilation features.

3. Bending

   Produces flanges, tabs and angles, with bend allowance and springback considered during planning.

4. Forming

   Creates ribs, embossments, offsets and other features that provide shape or function.

5. Deep Drawing

   Draws a blank into a cup, shell or housing shape. Material flow and forming stages need review.

6. Coining

   Uses localized compressive pressure to define selected details and surface geometry.

How the Operations Are Arranged

The die type describes the production arrangement; blanking, bending and drawing describe the work performed. The tooling route is confirmed after part and quantity review.

What We Review Before Tooling

• Material & Thickness Grade, temper or condition, sheet thickness and finishing requirements.
• Part Geometry Holes, bends, radii, drawn features and the intended assembly.
• Critical Features Functional dimensions, tolerances, burr direction and inspection requirements.
• Production Plan Sample needs, expected repeat quantity, tooling scope and secondary operations.

Tooling investment should be considered together with expected repeat demand. Tolerances, tooling schedules and production rates are confirmed for the specific drawing.
