6 types of metal stampings you should know 

In metal stamping, there are several processes that differ from one to another depending on the shape they achieve. Manufacturers perform this process to create complex designs for various applications, including consumer goods, aviation, electronics, and more.

There are several types of metal stamping, including piercing, coining, lancing, drawing, embossing, and blanking. Moreover, they might evolve in different techniques in a room-temperature environment without application. Different types of tooling dies and other tools make these cold-forming processes possible, allowing us to achieve the desired appearance.

At Texas Technology, we ensure our clients’ satisfaction by promptly answering all their queries and questions about metal stampings.

The types of metal stamping 

Piercing 

This method represents the basic form of metal stamping, where operators place sheet metal on a workbench to create various hollow areas. Unlike other techniques, they discard the resulting punching material from the entire process and do not use it later on.

In this process, it is essential to know the punching motion is instantaneously ensuring there is no deformation in the areas surrounding the hole formation.  

Manufacturers construct piercing machines from high-carbon steel and maintain them in good condition to prevent blunt areas that can affect the shape of metal workpieces.

Blanking

While blanking may seem similar to piercing, the key difference lies in the fact that blanking produces a punched piece that manufacturers do not discard and that is considered a finished product. Various metal stampers usually do this in the first phase of a metal stamping project, followed by techniques like piercing, bending, or coining.

Manufacturers use blanking to fabricate small or medium-sized metal pieces cut from large metal sheets. It creates an ideal possessor in both high and low-volume production due to the simplicity and the ability to create high-piercing metal cuttings. 

However, there are certain cases where metal products might have ended in burrs or unwanted edges. Moreover, operators commonly remove them through manual deburring or heat deburring.

Drawing

At Texas Technology, we help you understand the metal stamping process, where a machine holds the two opposite ends of a metal sheet in place.
Below the metal sheet that has a certain shape, cross-sections. A punch helps in producing high-impact force to push the metal sheet on a die for deforming to match the die’s cross-sections.

Moreover, we can further classify drawing into shallow drawing and deep drawing, where the latter involves a primary radius equal to the depth of the draw. Additionally, the drawing process typically produces cup-shaped products, with the radius of the primary blank being smaller than the created depth.

Coining 

As the name suggests, metal stamping is a technique that shapes a small piece of metal to match the features of your coin. In this closed die forging technique, operators either stamp the metal as a whole or in part by closing two dies toward each other on both sides of the metal.

One of the advantages is that it becomes capable of producing metal products that can have a high level of tolerance. It is a simple hospital where you can create permanent deformations on the product that increase the resistance against impacts and other kinds of physical abrasion. 

Lancing 

Unlike processes like piercing and blanking. Whereas, lancing is a type of metal stamping that does not end in the removal of metal pieces. Instead, the die and punch work in such a way that they both slit on sheet metal. However, this process does not produce scrap metal pieces like slugs, which operators discard during or remove after processing.

Lancing mostly creates shapes and designs across various metals. It has distinct features in a hook-like shape used for any application requiring vents, tabs, and openings.  

Embossing 

It is a technique where it produces unique raised surfaces on an area of the sheet metal. Embossing metals can be formed in various ways. Ways like a machine or dye set.

Embossing is used in a number of applications due to the various complexity of designs that can be formed in various ways. Some prime examples are car hoods,  door frames, and metal coverings. 

While steel and various types of metal can be embossed. Alumunium is the most used option due to its high machinability, making it lightweight, and its durability, which goes well with the benefits of embossing. 

Conclusion 

In conclusion, the most useful technique in metal fabrication is the metal stamping process. We classify it into various processes, such as piercing and blanking, which are the starting points in metal stamping projects and typically serve as secondary steps before creating the final products.
Complex techniques like drawings, embossing, lancing, and coining are capable of producing designs that are complex and don’t require further machining.
