In the context of metal
forming, the process of Deep Drawn Part comprises of
several different press forming operations such as punching, bending, flanging,
coining, blanking etc. For a sheet or tube of metal to be made useful, it needs
to be formed. These processes have been in use for several decades and have
evolved with the emergence of newer techniques over the years. Despite this,
there are certain drawbacks associated with stamping that tend to delay or
adversely affect commercial or industrial projects.
For instance, the biggest
challenge is investment in tooling systems. The entire set-up requires a
significant capital investment, the cost of which is passed on directly to
customers. Another aspect to consider would be production volume. Most
companies that cater to industrial players often find it difficult to cater to
small production volumes. Even if they do agree to deliver a limited batch, the
cost per part is significantly high. In such a case, the lead times tend to be
longer too.
With these drawbacks of
stamping become more evident to industries, there is a growing inclination
towards alternative methods such as sheet hydroforming and metal spinning.
Interestingly, the tooling costs of these alternative methods could be up to
85% less than conventional stamping tooling costs. While there are several
companies that offer such services, there are only a handful of companies that
offer world-class metal forming and fabricating services.
