Product Features

ITW Drawn Metals’ tooling design utilizes the full capability of the tools and the presses used to produce the part. Features like bulges, beads, and steps are added as the part moves through the tooling. Other intricate details like multiple holes, lances and cutouts, as well as in-line leak proof testing and product positioning censoring can also be introduced or achieved in the press.
 
ITW Drawn Metals can customize your part design with the following features:

Bulging
Material is displaced or stretched so that a portion of the part’s diameter is forced to protrude from the surrounding geometry.

Necking
Localized thinning that occurs during sheet metal forming prior to fracture. A portion of the part is reduced in diameter to less than the major diameter.  There is a significant transition from one diameter to the other.
