Metal stamping is one of the most versatile and cost-effective manufacturing methods used today. From automotive brackets and battery housings to electrical terminals and industrial hardware, stamped components are found in almost every industry.

But metal stamping is not a single process. In reality, there are numerous types of stamping, each designed to create specific shapes, features, and geometries. Understanding these stamping types helps engineers select the right manufacturing method based on part complexity, production volume, material type, and performance requirements.

In this guide, we explore 18 major stamping processes, explain what is a stamping, discuss how does stamping work, and provide practical stamping examples used in modern manufacturing.

What Is a Stamping?

Before understanding the different types of stamping, it is important to understand what is a stamping.

A stamping is a metal component produced by applying force to sheet metal using specialized tooling and press equipment. The process can cut, bend, form, shape, draw, emboss, or otherwise transform flat metal sheets into functional parts.

Stamped parts are used in:

• Automotive systems
• Electrical equipment
• Industrial machinery
• Aerospace applications
• Consumer products
• Medical devices
• Electronics manufacturing

The popularity of stamping comes from its ability to deliver high accuracy, repeatability, and production efficiency.

How Does Stamping Work?

Many manufacturers ask, how does stamping work?

The basic stamping process follows several steps:

Step 1: Material Selection

The appropriate material is selected based on application requirements.

Common materials include:

• Mild steel
• Stainless steel
• Aluminum
• Copper
• Brass
• Galvanized steel

Step 2: Tool and Die Setup

A specialized die is designed to create the desired geometry.

The die contains:

• Punches
• Forming tools
• Cutting features
• Guide systems

Step 3: Press Operation

The metal sheet is positioned inside the press, and force is applied through the tooling.

Step 4: Inspection and Finishing

Finished components may undergo:

• Deburring
• Cleaning
• Surface treatment
• Assembly

Depending on the design, multiple stamping operations may be completed during a single press cycle.

Top 18 Metal Stamping Processes

1. Blanking

Blanking is a cutting operation where a specific shape is cut and separated from the surrounding sheet metal.

The removed portion becomes the actual component.

Stamping Example

Blanking is commonly used to manufacture:

• Washers
• Brackets
• Electrical contacts
• Mounting plates

Why Is Blanking Important?

It serves as the foundation for many additional stamping operations.

2. Piercing

Piercing creates holes, slots, or cutouts in a metal component. Unlike blanking, the removed material is scrap, while the remaining piece becomes the product.

Stamping Example

Examples include:

• Bolt holes
• Ventilation openings
• Connector openings
• Fastener locations

Piercing is one of the most common stamping types used across industries.

3. Bending

Bending changes the shape of metal by forming an angle or contour without removing material.

Stamping Example

Bending is used for:

• L-brackets
• Mounting supports
• Electrical enclosures
• Structural reinforcements

This process transforms flat material into three-dimensional components.

4. Forming

Forming reshapes sheet metal into a new profile without cutting it.

Stamping Example

Common formed features include:

• Ribs
• Channels
• Contours
• Reinforcements

Forming improves structural performance while reducing material consumption.

5. Deep Drawing

Deep drawing creates hollow components by pulling material into a die cavity. The depth of the formed part typically exceeds its diameter.

Stamping Example

Applications include:

• Battery cans
• Sensor housings
• Cylindrical containers
• Motor housings

Deep drawing is widely used when seamless construction is required.

6. Progressive Die Stamping

Progressive stamping uses multiple stations within a single die to gradually create a finished part.

Each station performs a specific operation.

Stamping Example

Common applications include:

• Connectors
• Terminals
• Clips
• Automotive hardware

Progressive stamping is ideal for high-volume manufacturing.

7. Transfer Stamping

Transfer stamping moves individual blanks between stations rather than keeping them attached to a metal strip.

Stamping Example

Used for:

• Structural automotive parts
• Complex formed components
• Large metal stampings

Transfer systems provide flexibility for intricate part designs.

8. Fine Blanking

Fine blanking is a precision cutting process that produces smooth edges with minimal burr formation.

Stamping Example

Applications include:

• Precision gears
• Safety-critical components
• Mechanical assemblies

Fine blanking often eliminates secondary machining operations.

9. Coining

Coining uses extremely high pressure to create highly accurate features and surface details.

Stamping Example

Used to create:

• Logos
• Identification markings
• Electrical contact surfaces
• Precision details

Coining improves dimensional precision and surface quality.

10. Embossing

Embossing creates raised or recessed patterns on a metal surface.

Stamping Example

Applications include:

• Company logos
• Serial numbers
• Decorative patterns
• Reinforcement features

Embossing improves both appearance and structural rigidity.

11. Flanging

Flanging bends an edge to create a rim, flange, or lip.

Stamping Example

Common uses include:

• Automotive panels
• Appliance housings
• Equipment covers

Flanging improves assembly performance and part strength.

12. Curling

Curling rolls the edge of a metal component into a rounded profile.

Stamping Example

Examples include:

• Containers
• Appliance parts
• Consumer products

Curling improves safety by removing sharp edges.

13. Lancing

Lancing cuts and forms metal simultaneously without removing material completely.

Stamping Example

Applications include:

• Vent tabs
• Retention clips
• Mounting features

Lancing adds functionality while reducing assembly requirements.

14. Notching

Notching removes material from the edge of a component.

Stamping Example

Common examples include:

• Corner cut-outs
• Relief areas
• Assembly clearances

Notching prepares parts for future forming or joining operations.

15. Shaving

Shaving is a finishing operation used to improve edge accuracy and surface quality after cutting.

Stamping Example

Used for:

• Precision gears
• High-tolerance components
• Mechanical assemblies

Shaving helps achieve tighter tolerances than standard blanking.

16. Trimming

Trimming removes excess material after a forming or drawing operation.

Stamping Example

Applications include:

• Deep-drawn housings
• Containers
• Automotive shells

The process ensures final parts meet dimensional specifications.

17. Four-Slide Stamping

Four-slide stamping uses four independently moving slides to form complex components.

Stamping Example

Common products include:

• Springs
• Clips
• Fasteners
• Electrical components

This process allows highly efficient production of intricate parts.

18. Multi-Slide Stamping

Multi-slide stamping uses multiple tooling slides to produce complex geometries from wire or strip material.

Stamping Example

Applications include:

• Electronic contacts
• Medical components
• Precision metal hardware

Multi-slide stamping often reduces secondary operations and improves productivity.

How Do Manufacturers Choose the Right Stamping Process?

Selecting the right process depends on several factors.

Material Type

Different materials respond differently to forming and cutting operations.

Component Geometry

Simple parts may require blanking or piercing, while complex parts may require transfer or progressive stamping.
