Northern's skilled press brake operators were able to hold tolerances of +/- 0.06" along the critical venturi area of this 24' long, complex assembly.
 

Complex Sheet Metal Forming

Press brake forming is the most technically challenging operation in sheet metal fabrication. Northern excels in this area due to our vast experience in forming some of the most complicated shapes possible.
 

Perfect Bend Angles
Inline angle sensors allow for perfect bend angles without setup pieces. The machine does a "pre-bend" close to the desired angle and then measures the result. The software then corrects for the difference with a second hit, resulting in angles +/- 0.3 degrees. This eliminates error due to thickness varation, grain direction, and springback. Watch it work in the following video:

Case Study

 

Problem: A customer needed a custom formed shape in a 24 foot sub-assembly. The tolerance in a critical venturi area was +/- 0.06" and it was inspected by a go/ no go gage. The 24 foot long sections then had to be welded together to complete the assembly (pictured above).

Solution: Northern used its extensive experience with complex forming to produce the desired shape. We then achieved full welding penetration in the 3/16" material for the entire 96 feet of welding.

Results: The laser welding caused so little distortion in the final assembly that the critical venturi area stayed within it’s extremely demanding tolerance.
