Sheet Metal Stamping Processes & Techniques
One way that sheet metal is used in the manufacturing of products is stamping. Sheet metal stamping is used to produce parts used in electronics, household items, automobiles, and many other industries. The process of metal stamping involves creating metal parts by applying extreme pressure to a blank piece of metal and forming said metal into a desired shape. This shape is derived from a piece called a die.
FineBlanking
Fineblanking is a process of metal forming the combines stamping and cold extrusion. This process of stamping involves only one tool and one pressing motion. The tool itself, however, performs three separate motions to produce the finished product. Parts made using fineblanking typically are very flat, and have a fully sheared and straight edge to them as well as one or more small holes.
Deep Drawing
Another process of sheet metal stamping is Deep Drawing. This process involves stretching sheet metal stock around a plug. The plug then forces the metal stock into a die cavity which produces the desired shape. This type of stamping is commonly used to make items such a cups, cans, cylinders, pots or pans, domes, etc.
Four Slide or Multi Slide Stamping
This process of stamping is a bit more complex than the previously discussed methods. In four slide and multi slide stamping the metal or metal wire is approached from multiple sides or angles by the dies, either successively or simultaneously. This produces a final product that is either coiled or bent, depending on the desired result and dies used. This process is used to produce springs, clips, brackets, and other materials used in industries such as the construction and automotive industries.
These are just a few of the methods used in stamping sheet metal to manufacture products. Sheet metal stamping can be a very efficient and cost-effective way of manufacturing many different types of products and is widely used in the manufacturing industries from automotive to construction.
