During high-speed blanking, press stroking rate and punch speeds, are higher than in conventional blanking. As a result, the shear zone has a higher strain rate, which affects a workpiece's sheared surface temperature and the tool surface.
Fineblanking in various forms is increasingly becoming accepted by the automotive industry for producing sheet metal components with smooth edges that don't require additional finishing operations.
Fineblanking allows the production of sheet metal components with smooth edges in a single press stroke. This column discusses basic terminology and the principles of this process.
Hydroforming often results in localized thinning. Using engineered tubes—tubes that have a thicker wall where the tube is most prone to thinning—can result in a stronger finished component.

Passenger car fuel tanks have for many years been made out of plastic. To reduce MTBE leaks in the groundwater, the Department of Energy, The State of California, and the Western States Petroleum Association are studying material alternatives such as high-strength steel, stainless steel and aluminum gas tanks.
