Setting up a stamping die is one of the most critical steps in a successful stamping process. It's a fact: More damage is done to a die, especially a progressive die, in the first 10 hits than in the next 10,000 hits. Most die damage happens during initial setup, when the material is being fed into the die. Mistakes such as misfeeds, pilot piercing, double metal, sheared cutting sections, and stock hang-ups often occur.

As a consultant for the sheet metal stamping industry, I have had the opportunity to visit numerous stamping plants, die shops, and engineering facilities. One comment I often hear during these adventures is how arrogant or "know-it-all" some of the toolmakers or engineers are.

One of the most valuable high-tech tools introduced in the last decade has been finite element analysis (FEA) simulation software that stamping tool makers can use to test forming conditions and design dies in the virtual world. This reduces tooling and product design time and saves costs of prototyping and experimentation to find the right design. Training the tool designer or process engineer how to use simulation software can provide a quick ROI and improve the bottom line.

Take this old maxim to heart: A stitch in time saves nine. The same goes for die maintenance and repair.

Liquid impact forming, a patented process developed by Greenville Tool & Die Co., Greenville, Mich., uses a conventional stamping press with a liquid medium to manufacture parts that otherwise would require hydroforming.

You might be able to gain a competitive edge by learning how to reduce the amount of engineered scrap, or that material that was inteded to be scrap rather than scrap created because of defective piece parts.
