Therefore, it has become the most used technique when producing fuel tanks, fire extinguishers, kitchen sinks among other items related to the automotive industry. This type of stamping also works well if you want a strong component since it work-hardens materials during its operation and thus makes them tough. Moreover, this method saves money during mass production runs because it produces accurate complex shapes with little wastage at low costs per unit produced when compared against other methods available in the market today.
How to Design for Metal Stamping: Best Practices
To guarantee the efficiency and quality of the final product, there are a few best practices to follow when designing for metal stamping. To start with, you should pick an appropriate material that meets the performance requirements of the part as well as being suitable for stamping. It is also important that the design incorporates generous tolerances so that tearing or wrinkling does not occur due to material flow. Wherever possible make the geometry simpler; this can be achieved through features such as rounded corners and consistent wall thicknesses which in turn reduce tool wear while prolonging tool life. Another thing is that pilot holes can be used to enhance precision during alignment of parts throughout the stamping process. Furthermore, involve closely working with manufacturers of these stamps during design phase since they have more knowledge and experience on them than anyone else would do .
