Unfortunately, not many flights are taking off right now. Under normal circumstances, however, millions of airplanes hit the sky every day. People should use their newfound grounded time to think about how airplanes are made. The reality is, no plane could be built without a press brake. Press brakes allow operators to bend and manipulate a sheet of metal into nearly any desired shape. Aerospace professionals use a press brake to angle sheet metal that’s used as a protective layering on planes. Without a press brake, workers could never angle the metal as needed.
