Methods of Metal Stamping

There are many different methods used in metal stamping to create low-cost, high-speed, and high-precision products. Examples include:


In blanking, a piece of work is withdrawn from the host material and made into the desired shape. Unlike drilling, the removed workpiece becomes the desired shape or blank.

Advantages: High precision, efficient for mass production.

Applications: Used in automotive and electronics industries for producing flat components.


punching, the punch enters the material attached to the die and pushes out the sheet metal, molding the rest of the workpiece into the desired shape.

Advantages: Cost-effective for producing holes and intricate patterns.

Applications: Common in manufacturing parts for home appliances and electronic devices.


Placing the material between the mold and the press or punch is the entire process of casting. During the stamping process, the material is squeezed considerably, resulting in a part surface with minute features and tolerances.

Advantages: High detail and surface quality.

Applications: Suitable for parts requiring fine details, such as jewelry or decorative items.


The method of bending a sheet of metal into the L, U, or V shape one desires is called “bending”. The bending process takes place around a line above the yield point of the material to make the desired shape.

Advantages: Versatile and can create various shapes.

Applications: Used in the construction industry for creating metal frames and supports.


The flanging process is a flange or flare made on a workpiece using a mold and a flanging casting section. The desired shape of the workpiece is made by the flanging portion of the mold.

Advantages: Adds strength and rigidity to the part.

Applications: Common in automotive manufacturing for parts like wheels and panels.

Stretching or Molding

With the stretching and forming stamping process, pressure is applied to a sheet of metal to insert it into a hole or to shape it by wrapping it around a die with the desired shape.

Advantages: Can create complex shapes with smooth surfaces.

Applications: Used in aerospace for creating aerodynamic parts.


With the embossing process, you will need a die and a press or forming machine to place the shaped die on the material. The embossed pattern or designed shape is then embossed onto the workpiece.

Advantages: Creates decorative and functional features.

Applications: Used in the production of coins, medals, and decorative panels.


When curling, sharp edges can be removed or turned into hollow rings that conform to a specific pattern. When curling, the moment of inertia at the end of the item being curled is also increased.

Advantages: Improves the safety and aesthetics of edges.

Applications: Used in the furniture and automotive industries for edges and rims.


Piercing necessitates punching or cutting closed-shaped holes in the top. The punched portion is thrown away and the perforated portion is eventually used.

Advantages: Efficient for creating multiple holes in a single operation.

Applications: Used in manufacturing electronic components and metal fittings.

These different metal stamping methods can be used individually or in combination with each other to create the complex parts needed for a project. The most important thing to consider when choosing which metal stamping method to use is the uniqueness of the project.

For example, bending can be used to create simple bending designs, while flanging and piercing or any of the other methods mentioned above can be used together to create complex molded parts.

Different Types of Stamping Metals

Different types of metal stamping are used in different ways to create finished parts that meet high-quality standards. Progressive die stamping, deep drawing stamping, and four-slide stamping are the three main types of metal stamping.

Progressive Die Stamping

We move a strip of metal from one place to another by means of a progressive die-stamping machine. This is also known as “progressive die stamping“. Each station has a specific job to do, such as stamping, bending, cutting, or shaping.

Most progressive stamping jobs necessitate more than one station or stage, especially if the item is intricate. The advantage of progressive stamping is that it allows for the rapid production of a large number of identical parts. It also offers the lowest processing costs of any stamping method.

Deep Draw Stamping

As part of deep drawing stamping, the blank is fed through a punch into a die. It is best suited for jobs where the customer wants the part shape to be very deep. Parts with transverse and longitudinal deep shapes are often used in the aerospace and automotive industries. Deep drawing uses less raw material than stamping. It is also suitable for manufacturing large quantities of less complex parts.

Four-slide Stamping

Four-slide stamping is a metalworking method that makes it easier to create complex parts. It has four tools that bend the metal into the correct shape at the same time. While progressive stamping makes parts that are more regular, four-slide stamping makes it easier to change the design when a project requires a large number of parts with different curvatures.

When selecting the best metal stamping process and method, a number of key criteria must be addressed. Some of these factors include manufacturing budget, part shape and size, production speed and quality, and production volume. You can refer to the table below to choose which method to use.
