Metal stamping is a cold-forming technique that involves the use of dies and stamping machines to shape sheet metal. Blanks, or pieces of flat sheet metal, are fed into a sheet metal stamping press, which uses a tool and die surface to mold the metal into a new shape. Stamping services are provided by production facilities and metal fabricators who position the material to be stamped between die parts and apply pressure to shape and shear the material into the appropriate final shape for the product or component. Read this article so that you will be introduced to metal stamping.
Punching
It refers to the cutting of material into precise shapes using a die. As the punch penetrates the die, a scrap piece of material is removed, leaving gaps in the workpiece. Blanking, on the other hand, involves removing a component from the source material and repurposing it as the desired product or blank.
Flanging
is the process of using dies, presses, or specialized flanging machines to apply a flare or flange to a metal workpiece.
Embossing
It is by pushing the raw sheet against a die that holds the required shape, or by rolling the material blank through a roller die, an elevated or sunken design in sheet metal can be created.
Coining
It is a bending skill that enables stamping the workpiece while it is sandwiched between a die and a punch or press. The punch tip penetrates the metal as a result of this movement, resulting in precise, repeatable bends. Tensile forces in the metal workpiece are also relieved by the deep penetration, resulting in no spring return effects.
Bending
It refers to the process of shaping metal into desirable shapes like L, U, or V-shaped profiles. When metal is bent, it undergoes a plastic deformation that causes stresses over the elastic limit but underneath the tensile strength. Bending usually takes place around a single scale.
Final Stamping
Deburring, tapping, reaming, and counterboring are some of the post-stamping production activities that can be performed on the stamped product. These enable for the addition of other pieces to a stamped object, as well as the repair of finish flaws and the elimination of sharp edges that could compromise safety. Deburring is the process of removing cut material fragments that remain on the surface after the pressing operation is finished. Sharp edges may need to be ground to remove burrs or flanged over to create a smoothed edge and divert the burred edge to the inner fold, where it wouldn’t cause injuries or be seen cosmetically.
Key Takeaway
Stamping is utilized in a wide range of applications, including three-dimensional designs, lettering, and other surface engraving elements. Home appliance manufacturers, auto manufacturers, lighting companies, telecommunications services, military and defense, aerospace industries, medical equipment makers, and electronics companies all use stamping products. Metal stamping is a procedure utilized in anything from household appliances to automobiles, so chances are you have an object in your home that uses it. That is how metal stamping is used. Now you know.
