6 common metal stamping processes

In metal stamping processes, they differ in type depending on the shape they reach. According to different industry needs, forging a variety of complex design processes, such as common consumer goods, aviation, electronics, telecommunications, automobile manufacturing, and other industries, the whole metal stamping project used in the process is diverse, with each process in the sheet metal achieving a specific design.

Some types of metal stamping include perforation, mint, spray gun, drawing, embossing, and blanking. Although they may involve different techniques, they are all performed at ambient temperature with little heat. These cold forming processes are achieved through different types of molds, machinery, and other tools to achieve the desired appearance.

Bore a hole

Perforation is one of the most basic forms of metal stamping. In this method, the sheet metal is safely placed on the workbench. the metal plates with machining tools to create several small hollow areas. Unlike other techniques, the punch material produced throughout the processing is discarded and will not be used later.

It is important that punch movements remain instantaneous in this type of process. This ensures that the area around the hole does not deform. Perforators are usually made of high-carbon steel and must remain in good condition to avoid anything that may affect the shape of the metal workpiece.


The ping looks similar to perforations, but there is a major difference: punches are not discarded but are treated as the finished product. Many metal stamping machines usually use this as the first stage of the entire metal stamping project, followed by other techniques such as perforation, bending, or stamping.

The PP is to process small or medium-sized metal cut from large metal sheets. This is an ideal process for both low-yield and mass production due to its simplicity, but it is also capable of creating high-precision metal cutting.

However, in some cases, the cut metal product may have burrs or sharp excess edges. Although they are common, they are usually removed by manual deburring, vibrating finishes, or thermal deburring.


When it comes to metal stamping, the manufacturer usually refers to the stretching process. This is a machine to hold the ends of the metal plate together. Below the sheet metal is a mold with a certain shape or cross-section. The punch produces a high impact force to push the metal plate onto the mold, effectively deforming it to match the cross-section of the mold.

Streensches can be further divided into shallow and deep stretches. The shallow tensile depth is called the shallow tensile depth because the radius of the primary blank is equal to the deep stretch. At the same time, the depth usually forms a cup. This is where the radius of the major blank space is significantly smaller than the depth created.


Stamping metal plates

As the name suggests, forging is a metal stamping technique that presses a small piece of metal into the shape and characteristics of a coin. This is a closed die forging technique in which the whole or part of the metal sample is stamped, consisting of two molds on the sides of the metal close to each other.

One advantage of casting is its ability to produce metal products with a high tolerance. It is also a simple process that can effectively produce permanent deformation on the product. This increases its resistance to shocks and other physical abrasions.


Unlike piercing and blanking, piercing is a metal stamping that does not remove metal parts. Instead, the mold and punch work as they both create a crack in the metal plate. This process does not produce scrap iron sheets, such as those that must be discarded or removed during post-processing.


Stamping sheet metal embossing

Embossing is a technique that produces unique raised surfaces on metal sheets. Emssed material can be produced in two ways: by using machines or die sets.

Due to the complexity of the designs that it can form, embossing can be used in many applications. Some of the main examples are car covers, door frames, metal covers, plates, engine housing, grid plates, etc.

Although steel and various types of metal can be embossed, aluminum is the most popular option because of its high processability. It is also a lightweight and durable material that combines well with the benefits of embossing.
