Bending the new breeds of high-strength steel
This heavy-duty gooseneck punch with an acute-angle 1V die provides the ability to overbend material to compensate for springback.
Since the early 1980s, sheet metal fabricators have, for the most part, followed a pretty basic set of rules to air-bend mild steel. To determine the... Read more...

Hot forming: Strong meets light
One of the challenges of meeting the NHTSA requirements for increased part strength while also meeting the CAFE requirements for decreased weight is that cold-stamped UHSS parts have a tendency to spring back. To meet this challenge, Cosma experimented with hot forming complex parts. The... Read more...

Understanding press feeds
A press feed must not only move the proper amount of material into the tool, it must position it correctly into the die—front to back, side to side, and square with the tool. In this case, it must also gently handle prepainted coil to prevent scratching it. Over the last decade... Read more...
