New PC-based controls open path to better press brake utilization

November 6, 2003

By:

Press brake forming always has been a labor-intensive process. Shrinking lead-times and smaller lot sizes demand more frequent setups, which cut into productive output hours and put more pressure on manufacturing efficiencies. Fabricators need to find ways to reduce machine downtime for setup and operator adjustments.

March for manufacturing

October 23, 2003

By:

As the "jobless" recovery continues, the job cleansing of the U.S. manufacturing base tops 2.7 million. These millions now without jobs remain faceless, statistical footnotes to mainstream media reports about how the recession ended in 2001, production is on the rise, and how job losses are singularly attributable to productivity gains. The outsourcing of the American dream for small manufacturers proceeds unabated.
