Sheet metal forming is a manufacturing process in which flat sheet metal is drawn into a die cavity to form a product shape. Draw-in amount is the single most important metal stamping index that controls all forming characteristics (strains and stresses), formability failures (splits, wrinkles) and surface quality (distortions) on a panel.

Method for modifying a metal stamping die to compensate for springback includes the steps of metal stamping a first part using a base, or pre-existing die set, and creating a surrogate die having the shape of the first stamped part. These steps are followed by simulated metal stamping of a blank with the surrogate die, where the blank is shaped according to the desired finished part.

In today's global environment, the "one size fits all" approach is used for so many products that we expect it to apply to just about everything. In the mechanical seal industry, one problem with that philosophy is the definition of the word all. Mechanical seals must live in literally every environment under the sun-from extreme hot to extreme cold, wet to dry, solid to gas, acidic to caustic and so on.
