Low-EAU Part Better Off Fabricated than StampedApril 1, 2011
Instead, Ultra Tool manufactured the parts in its new fabrication department, boasting a Salvagnini L1Ce fiber-laser cutting machine and a Durma 150-ton CNC press brake.
“Typically we look for a maximum 2-yr. payback to justify progressive tooling,” says Matt Schemelin, an Ultra Tool sales engineer. “With such a low EAU, payback for the progressive tooling for this job would have taken more than 8 yr.”
Ultra Tool added its fabrication department during the summer of 2010 to accommodate lower volume orders. Its Salvagnini laser-cutting machine (left) boasts a 60- by 120-in. worktable, 3000-W laser and positioning tolerance of ±0.0004 in. Cutting capacity in steel is 0.70 in., 0.312 in. for stainless steel. The Durma press brake offers a maximum bending length of 120 in., throat depth of 16.1 in. and a 14-in. stroke.
