Sheet Metal Stamping Press Machine: How It Works and Applications

JDM

In manufacturing, stamping press brings to mind heavy machinery weighing several tons that can permanently reshape metal with sheer brute force.

It's hard to deny that our daily lives are filled with products from sheet metal stamping machines. From the car you drive to the stove you use at home, metal stamping parts play an important role.

Choosing the right sheet metal press manufacturer to purchase the right machine or the right fabricator can be a good choice.

Read this article, which will take you through the following.

 

What is Metal Stamping?

Before we can understand the application of stamping, we must understand what it is.

The technical definition of metal stamping is that it is a cold forming process that uses extreme force and/or speed to permanently change the shape of a piece of metal. In the case of sheet metal stamping, the workpiece is sheet metal. However, metal stamping machines can also be used for wire and other forms of metal.

Simply put, the machine uses a die to create the shape of the metal. Steel, brass and aluminum are some of the most commonly used metals. The stamping process may look different depending on what is being manufactured, but the shapes are usually made from sheet metal, placed on a stamping die and put into a press.

 

How Does a Sheet Metal Stamping Press Work?

The basic operation of a metal stamping press is simple: put the material into a machine that can quickly apply several tons of force and use them to press the metal object into the shape you want.

Sheet metal stamping machines can typically perform several different processes.

  • Flattening metal

    One of the most basic operations of a stamping machine is to flatten a metal object. This can be done to smooth the object or to make it thinner at a certain point for other purposes.

  • Forging round metal

    This is similar to flattening because it makes the workpiece thinner, but this process is usually used for wire rather than sheet metal. Profile-forged wire makes one end narrower so it can fit more easily into an opening.

  • Perforated metal

    Instead of simply flattening the metal, the tools and dies of a sheet metal press can pierce a piece of metal. This creates openings that can be used to join multiple pieces.

  • Casting metal

    Instead of punching a small hole in a piece of metal, the tools and dies of a sheet metal stamping press can be used to punch the sheet metal into a specific shape (such as a coin).

    Since sheet metal stamping machines process cold metal pieces that have not yet been given ductility, they must rely on great force to get the job done - which is why these machines are often equipped with very powerful motors.

 

Advantages and Disadvantages of Sheet Metal Stamping

Metal stamping is a precise science that requires extensive training and practical knowledge of physics. There is little room for error with this service, so it's important to find a company that takes their work seriously. Otherwise, you may be looking at defective products.

Advantages

If you need to create metal parts, assemblies or products, investing in a proper sheet metal stamping machine can provide you with great benefits.

  1. Accuracy

    If your product requires high precision cutting, a stamping company will have the tools and processes in place to perform this operation. Cutting shapes with this kind of precision can be a huge expense, and it can be tempting to reduce costs due to the lack of this area of production.

  2. Consistency

    Consistency in mass production can be achieved by carefully controlling the entire process, starting with accurate computer-aided design (CAD), proper tooling, professionally operated metal stamping machines, and quality control that inspects each part or component and ensures consistency in the product.

  3. Mass Production

    A very large number of sheet metal stamping machines can be used for fast, continuous production without waiting for the part to cool down. And waste can be reduced.

Disadvantages

  1. Initial cost may be higher than other manufacturing methods

  2. Longer lead time to initial shipment (tool lead time)

  3. Often, more difficult to integrate revisions and/or part design changes

 

Applications in Different Industries

Industries for sheet metal stamping companies include (but are not limited to)

  • Automotive

  • Industrial machinery

  • Consumer electronics

  • Aerospace

  • Electrical

  • Telecommunications

  • Medical Devices

The automotive industry is a major market for the metal stamping industry, however, the use of metal fabrication in the consumer electronics industry is growing rapidly in this technology generation.

This means that almost all companies that use consumer electronics in the workplace rely on products made by metal stamping machines.

Other small industries that produce products such as jewelry and household appliances can mass produce products with the help of metal stamping presses.

Metal stamping presses and different metals

Stamping companies do not usually discriminate when it comes to metals. There are many different types of metal stamping presses that can be used, depending on the product and the need.

  • Steel

    Because of its strength, steel can be pressed into products that require durability and resistance to the elements. Metal stamping steels are used in automobiles, medical machinery and aerospace equipment.

  • Aluminum

    Lightweight, durable and flexible, it is used in a wide variety of industries.

  • Brass

    Used in electrical equipment due to the electrical properties of the zinc and copper that make it up.

  • Copper

    Like brass, its properties make it very useful for electronic instruments.

 

At the End

What can you get out of all this? The use of metal stamping is very common. Almost every business is influenced by metal stamping products. Metal stamping helps make computers, musical instruments and car engines. But there is no doubt that investing in a sheet metal stamping press is a significant investment, and choosing the right sheet metal stamping press manufacturer is an important choice.
