In the context of metal forming, the method of metal stamping comprises of several different press forming operations such as punching, bending, flanging, coining, blanking etc. For a sheet or tube of metal to be produced useful, it must be formed. These processes have been around in use for all decades and have evolved with the emergence of newer techniques on the years. Not surprisingly, there are certain drawbacks associated with stamping that have a tendency to delay or adversely affect commercial or industrial projects.
As an example, the biggest challenge is investment in tooling systems. The whole set-up takes a significant capital investment, the price of which will be handed down straight to customers. Another aspect to consider could be production volume. Most companies that appeal to industrial players often find it difficult to appeal to small production volumes sheet metal stamping company. Even when they do agree to provide a restricted batch, the cost per part is significantly high. In this case, the lead times are generally longer too.
With these drawbacks of stamping become more evident to industries, there’s a growing inclination towards alternative methods such as sheet hydroforming and metal spinning. Interestingly, the tooling costs of these alternative methods could be around 85% significantly less than conventional stamping tooling costs. While there are many companies that provide such services, there are only a number of companies that provide world-class metal forming and fabricating services.
Let’s take a go through the great things about these alternative metal forming methods:
Metal spinning: Also called spin forming, this technique allows a fabricator to use a metal disc or tube to change it into an axially symmetric part. That is accomplished by spinning the metal on a high-speed lathe. In some instances, the spinning process is carried out manually too. Different types of ductile metals could be formed using this particular method. The metal spinning technique is very cost-effective and can be suited to high volume part production.
Hydroforming: This technique involves the use of highly pressurized fluid for shaping and contouring a metal sheet. Whether it is a smooth contour or intricate angles, you are able to achieve a well-finished part applying this method. That is one of the very most cost-effective types of shaping ductile metals like stainless, aluminum, and brass among others. The parts thus formed are generally structurally strong, which explains why automobile industries are increasingly applying this method.
Parts formed using these techniques are compliant with the prevailing industry specifications. The aerospace and defense sector, automobile industries, nuclear industry, furniture manufacturers, and the HVAC sector are increasingly choosing forming methods other than metal stamping. These methods can handle producing nearly any part or component this one might expect to accomplish through metal stamping.
