# PAM-STAMP - Virtual Prototyping

## Virtual Prototyping of the Full Stamping Chain with PAM-STAMP

In the early days of simulation, it was about simulating the forming stage with the objective to eliminate cracks and wrinkles. Then simulation technique moved on to springback and the compensation thereof. With PAM-STAMP it is possible to do a full virtual prototyping of the whole stamping chain, including:

• Forming and springback
• Restrike and springback
• Flanging and springback
• Hemming and springback

This allows the engineer to have full control over the whole stamping process, ensuring highest quality and no “surprises” during physical prototyping.

## Precise Engineering Cuts Progressive Die Start-Up Costs by 80% with PAM-STAMP Stamping Simulation Solution

Computer simulation reduced the amount of time and money required to determine a successful forming process based on the defined stock width from an estimated US$18,000 to only US$3,600, concluded Rick Barnard, Precise Engineering’s General Manager. “The key to these savings was the use of PAM-STAMP to quickly and inexpensively simulate the performance of a wide range of die designs. Creating a virtual reality progressive die takes the try-out process off the shop floor and into the engineering office where it can be carried out faster and without tying up presses. We determined the process, developed the initial blank, accurately determined the flow of material during the first draw form, evaluated the impact of springback on finished tolerances, and monitored thinning percentages before we even began building the die.
