Sheet metal stamping is also known as “stamping”. This is a process that uses a lot of force to change the shape of a flat sheet of metal. The process may also involve punching holes in the metal.
Sheet metal stamping is a very common process. In fact, sheet metal stamping is part of the production process for most automotive components. See below for a more detailed explanation of sheet metal stamping.
Advantages and disadvantages of sheet metal stamping
Sheet metal stamping is a quick and easy process. This is a cold forming process. This means you don’t need to allocate any time for the stamped metal to cool down. Sheet metal stamping is the ideal solution if you need:
Poke a hole. You can’t punch holes with some other processes, but you can stamp them with sheet metal. For example, if you decide to use hydroforming for other reasons, you will need to use a separate process to punch the holes in the part. Costs can add up.
Multiple holes are pierced at once. A single stamping operation can punch multiple holes in sheet metal.
Create multiple complex bends. Sheet metal punching machines can produce multiple complex bends in one punching operation.
Metal stamping has several disadvantages:
High upfront tooling costs. If you’re doing low volume production, the upfront tooling costs can make it expensive. The sheet metal stamping process requires two dies—one concave and one convex.
Longer lead times. It takes more time to design and manufacture two molds instead of one.
A little more scrap metal. For sheet metal stamping, the metal sheet must overlap the die a little. This produces more metal scrap than other processes.
Despite these drawbacks, sheet metal stamping is still a great solution. It is the first choice of companies around the world for many types of parts.
