Virtual tryout
In this era of global warp speed and virtual reality, calculating the deep draws of progressive dies or the springback of metal is performed by simulation software instead of the earlier trial-and-error method. These software programs essentially replace the artistic methods of diemaking... Read more...

Maximizing a coil fed press
Modern Coil-fed Presses Stamping processes revolve around two basic styles of tooling, transfer and progressive dies. They both require feed-to-length systems but differ in many key areas. Blanking processes could be added but are progressive in nature. Transfer tooling requires material to be... Read more...

Which wire do you require?
Many fabricators overlook the efficiencies they can gain by changing a wire or process. In fact, when you ask fabricators why they're using a particular electrode, some respond with "That's the way it's always been done here," even though another way might yield significant improvement....

High-speed feeding techniques
The maximum operating speed of a stamping operation should be limited, in theory, only by the maximum number of strokes per minute (SPM) that the press can achieve. In reality, production speed is limited by other factors as well. For instance:
