What is Metal Stamping? How Does It Work?

Metal stamping services are important for various industries. In the US alone, there are thousands of companies that offer metal stamping services to deliver components for industries such as medical, aerospace, automotive, and many more.

As the global market evolves, the need for metal stamping services continues to increase. In this post, we focus on metal stamping basics, types of metal stamping and their applications, the flaws or defects caused during the process, and inspection solutions for the defects – AOI (Nova Series).

What is Metal Stamping?
Metal stamping is a cold-forming manufacturing process used to transform flat metal sheets into specific shapes. This complex process makes use of dies and stamping presses to convert metal into a new shape.

During this process, the material will be subjected to pressure that will shape and shear the material into the desired shape. Metal stamping is widely used in production facilities and metal fabricators offering stamping services.

It is a fast, highly durable, and cost-effective solution for large-quantity manufacturing needs for both short- or long-term production runs. Metal stamping may consist of one or more metal forming techniques, such as blanking, bending, punching, coining, flanging, and embossing.

Metal stamping machines may do more than just stamping. For instance, they can cast, punch, cut, and shape metal sheets. However, before forming the material, stamping professionals must design the tooling machine via CAD/CAM/EDM/CNC engineering technology.

EDM (Electrical discharge machining) and CAD (Computer-aided design) ensure accuracy. CAM ensures that each punch and bend maintains proper clearance, hence, optimal part quality. CNC (Computer numerically controlled) offers high precision and repeatability for every stamped piece.

Metal Stamping Application
Metal stamping is used in a wide range of applications, particularly those involving 3D (three-dimensional) designs, lettering, or other surface engraving features.

From your cars to your household appliances, chances are you already have a product in your home that has its parts created via metal stamping. For example steering wheel components, horn buttons, and power tools and etc.

Stamped metal components are also in use in the electrical, aerospace, military & defence, lighting, and medical industry.
