Metal stamping is a commonly used process when creating objects that primarily use metal in their production.

This method involves shaping and forming metal into different sizes and shapes using specialised tools and machines.

However, there are several types of metals that you can use for your projects. You may wonder what type of metal is best for your unique use case. Keep reading to discover some things you should consider when choosing a material for metal stamping.

What Is Metal Stamping?

Metal stamping is a commonly used manufacturing process that involves shaping and cutting flat metal sheets into various shapes and forms, such as electrical housings, gear components, mining system components and automotive electronics.

It is widely used in industries like automotive, aerospace, and electronics for producing a range of metal components. The process itself involves the use of specialised machines to press, cut, bend or stretch metal parts into specific shapes.

Processes Involved in Metal Stamping

The process of creating a custom metal prototype through metal stamping involves several steps, including:

  • Stamping: This is a cold-forming method that is used to shape and transform flat metal blanks into various forms, shapes, and sizes. The stamping process uses a tool and die, which changes its form when in contact with the metal sheet due to the pressure exerted.
  • Bending: With press brakes, rolling machines, and other relevant equipment, metals are manipulated to create basic shapes such as U-bends or V-bends.
  • Punching: This process involves creating holes in a metal surface using a punch and die. It is often made with hard metal and used to perforate holes into metal sheets simply by exerting force.
  • Welding: This can be achieved using several methods including stick welding, MIG, and TIG. Welding doesn’t always have to be used and is only necessary if a metal part is made up of two separate metal components. Once these separate parts are joined together, they can be finished using several post-processing methods, such as powder coating, anodising, and bead blasting. These methods will give the welded part a more refined finish.

7 Things You Should Consider When Choosing a Material for Metal Stamping

Choosing a material for metal stamping should involve careful consideration of the project’s needs and requirements. Here are seven things to keep in mind when deciding on a material for metal stamping:

1) Strength Requirements (for the finished part)

One of the most critical factors you need to consider when choosing a material for metal stamping is the strength requirements of the final product. This is because some materials are stronger than others, and you must choose the one that best suits your project’s needs. Consider the type of force and stress that will be exerted on the part to determine the level of strength it requires.

2) Aesthetics

The material finish is another important aspect to consider when choosing a material for metal stamping. If your project requires an aesthetically pleasing finish, you will need to select a metal that can be easily finished using methods like painting, powder coating, or polishing. Some materials have a natural sheen and require minimal finishing processes.

3) Geometry

The geometrical complexity of a part can also be a determining factor when choosing a material for metal stamping. Some materials are better suited to intricate shapes and designs, while others may not be able to maintain their shape when manipulated. It is essential to consider the type of design or shape you want to achieve and choose a material that can handle it.

4) Joining

Depending on the project, you may need to join two or more metal parts together. In such cases, it is important to consider the welding properties of different materials and choose one that can be easily joined with other components.

5) Corrosion Requirements

If your project will be exposed to extreme environments or elements that can cause corrosion, you need to consider the material’s resistance to corrosion. Some materials are more resistant than others and will be better suited for projects with these requirements.

6) Desired Weight

The weight of a finished part should also be taken into account when selecting a material for metal stamping. Some materials are denser than others, and if your project requires a lightweight component, you may need to choose a material that is less dense.

7) Formability

Lastly, consider the formability of different materials. Some metals are more easily shaped and formed than others, which can be an important factor if your project requires complex shapes or designs.

Why is it Important to Select the Right Material?

Selecting the right material is very important for several reasons:

  • Cost: Different materials have different costs associated with them, and choosing the wrong one can be expensive.
  • Product Use: The material used will affect the final product’s durability and functionality. Choosing the wrong material can result in a weakened or damaged part.
    • Durability: Using the wrong material can result in a finished product that is not durable or long-lasting.
    • Functionality: The material used will ultimately determine how well the part functions for its intended purpose.
  • Design Requirements: Certain materials may not have the necessary properties to achieve a specific design or shape, resulting in an unsuccessful project.

How We Can Assist You At Formero
