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.
