During metal forming, metallic stamping consists of several different molding operations, such as punching, bending, flanging, forging, lowering, etc. It is necessary to form the metal sheet or pipe to be used. These processes have been used for decades and have been developed in recent years by developing new techniques. However, there are certain drawbacks of stamping that are likely to delay or adversely affect commercial or industrial projects.
For example, the biggest challenge is investing in the tooling system. The whole structure requires substantial capital investment, the cost of which goes directly to customers. Another aspect is the production volume. Most of the companies serving the industry often encounter difficulties in small production volumes. Even if you agree to a restricted item, the cost per share is considerably high. In such cases, lead times are usually longer.
These disadvantages of stamping become more apparent to industries, but alternative methods such as flat hydroforming and metal rotation tend to be increasingly pronounced. Interestingly, the cost of molding these alternative methods can be up to 85% less than traditional stamping tools. While many companies offer such services, only a few companies offer world class metal forming and manufacturing services.
Let's look at the advantages of alternative metal forming methods:
- Metal Rotation: Also known as Spin Forming, this method allows manufacturers to use metal plate or tube to form axially symmetrical portions. This is achieved by turning the metals on a high-speed lathe. In some cases, the spinning process is performed manually. Different types of curling metals can be formed by this method. The metal rotation technique is very cost effective and it is also suitable for large quantities of part production.
- Hydroforming: This technique involves applying high pressure liquid to form and contour a metal sheet. Regardless of whether it is a smooth contour or complex angles, you can achieve a well-developed part with this method. This is one of the most cost-effective ways to form curly metals such as stainless steel, aluminum and copper. The resulting parts are generally structurally strong, which explains that automakers are increasingly using this method.
Parts with these techniques meet the prevailing industry standards. The astronaut and defense sector, the automotive industry, the nuclear industry, furniture manufacturers and the HVAC industry are increasingly designing metallic stamps . These methods are capable of producing exactly the parts or components that can be achieved with sheet metal.
