Metal stamping is a process that involves several operations, such as punching and bending, flanging or coining, as well blanking. To make a sheet of metal or tube useful, it must be formed. You can know more about alloy stamping online.

These methods have been used for many decades and have improved over time with the introduction of newer techniques. However, stamping can have some drawbacks that may delay or negatively affect industrial or commercial projects.
Investment in tooling systems is the greatest challenge. The whole setup requires significant capital investment. Customers pay the difference. Production volume is another aspect that you should consider.
Many companies catering to industrial customers find it difficult to handle small production volumes. Even if they agree to deliver a small batch, the price per part can be very high. These cases tend to have longer lead times.
These drawbacks of stamping are becoming more apparent to industries. There is an increasing desire for alternative methods like sheet hydroforming or metal spinning. These alternative methods can cost up to 85% less than traditional stamping tools.
Let's have a look at the benefits of the various metal forming techniques.
Metal spinning allows a fabricator to create an axially symmetrical component using a metal tube or disc. The metal is spun on an automated high-speed lathe to do this. The rotation can sometimes be done manually. This approach can be used to create a wide range of ductile materials.
Hydroforming: This is a technique that uses highly pressurized fluid to contour and shapes a metal sheet. This method can produce a finished part regardless of whether it's a flat contour or intricate angles.
