What is Stamping Process ?

A stamping process is a method of forming a work-piece (usually metal) by pressing it with a die. It is related to forging, except that in forging, the work-piece is usually heated before it is shaped. In stamping, the work-piece is usually cold. The advantage of stamping over forging is that it is easier to produce complex shapes with stamping.

Stamping Process is often done as a final step in the manufacturing process, but it can also be used to create a prototype or sample of a product. In this process, a die is used to create a raised impression on a work-piece. The die is usually made of hardened steel (or) any metal and is mounted on a press. The press applies force to the die, which transfers the force to the work-piece, creating the impression.

The stamp may be made of any material, but is usually made of a metal or other hard material. The design or pattern may be impressed on the surface by means of a die, which is a raised image on the stamp, or by means of a plate, which is a flat surface on which the design or pattern is impressed.

To ensure the metal piece turns out the way it is supposed to be, the stamping professionals need to use the design tools which comes along with CAD/CAM engineering technologies. These designs must be as accurate as possible for each component to come out of the process, looking and operating how it should be.

Since,the metal stamping process can manufacture a high volume of similar components in a short amount of time, it is used in a variety of industries.


There are more processes or techniques available in stamping process used to shape a metal.

Each type of stamping has its own advantages and disadvantages, and the best type of stamping for a particular project or work-piece depends on the desired requirements.

1) Die Cutting – Die cutting is a process where a die is used to cut out a shape from a piece of paper.

2) Embossing is a type of stamping procedure that raises the design or image above the surface of the work-piece. This can be done using a die or a punch, and the resulting image is often three-dimensional. Embossing is commonly used to add a decorative element to a product, and it can also be used to create a raised surface that can be felt or grasped.

3) Debossing is the opposite of embossing, and it involves pressing the die or punch into the surface of the work-piece to create an indented design or image. Debossing can be used to create a negative image of a design, and it can also be used to create a raised surface.

4) Punching is one of the stamping techniques, which is used in the process of separating the waste or unwanted materials from the work-piece, along with the closed contour to obtain the part which contains the holes.

5) Bending is quite a special technique that uses specially designed die or general die in folding (or) bending a sheet metal along a straight axis based on the customer’s requirement. This is a high precision and consistent process used for product development, but certain things like bending angle, radius, Applied force, etc. must be monitored and controlled accordingly.

6) Blanking is the process of cutting a piece of sheet metal into a desired shape or size.

7) Coining – Coining is a process where the metal is deformed by force, usually using a punch, to create a desired shape.

8) Heat stamping is a type of stamping that uses heat to transfer a design or image onto a work-piece. Heat stamping is often used to create a permanent image on a variety of materials, including paper, plastic, and metal. This is a versatile process that can be used to create a wide range of results, from a simple design to a complex image.

9) Cold stamping is a type of stamping that uses a cold die or punch to transfer a design or image onto a work-piece. Cold stamping is often used to create a temporary image on a variety of materials, including paper, plastic, and metal. Cold stamping is a versatile process that can be used to create a wide range of results, from a simple design to a complex image.


a. MECHANICAL PRESSES – Mechanical presses use a flywheel to store energy and then release it in a rapid, controlled manner. This type of press is versatile and can be used for a variety of stamping operations.

b. HYDRAULIC PRESSES- Another type of stamping press is the hydraulic press. Hydraulic presses use hydraulic cylinders to generate the force needed to operate the press.These presses are specifically used for high-force applications such as deep drawing and forging.

c. PNEUMATIC PRESSES – Pneumatic presses use compressed air to generate the force needed to operate the press. They are typically used for lighter-duty applications such as stamping small parts.

d. MECHANICAL SERVO PRESSES – It uses servo motors to drive the various components of the press. The servo motors are controlled by a computer program that regulates the speed, pressure, and position of the stamping process. Servo-type stamping presses are used in a variety of industries, including the automotive, aerospace, and electronics industries.

Each type of stamping press has its own advantages and disadvantages. The type of press that is best for a particular application depends on the nature of the application and the desired results.


The steps involved in stamping are as follows:

Step 1: The first step is to establish the blank shape, which is the material used to create the part. The material is then cut and formed into the shape and size of the part, and is typically done with a shearing and blanking press.

Step 2: This next step is followed by the forming stage, which includes operations like drawing, embossing, and coining to shape the blank by stretching it around a metal punch.The die transfers the force to the work-piece, creating the impression. This stage is typically made up of a series of presses and rollers, specially designed tools that push, pull, fold, and bend the material.

Step 3: After the metal is formed, additional operations such as punching, notching, and bending may be used to refine the shape and accuracy. And the work-piece is removed from the die.

Step 4: The final step is finishing, which involves trimming off any excess material and polishing it for a clean, professional look. The surface of the part is also often treated for corrosion resistance.

One of the most important finishing operations in the stamping process is the de-burring or de-flashing process. This is the process of removing the burrs or flash created by the stamping process, which are often sharp and may be hazardous.

This helps ensure that all parts meet the same exact specifications, and can help reduce overall costs through precise trimming which minimizes waste and minimizes how much material must be used.

Difference between Stamping and Forging process
