Press brake bending basics: Tooling choice when forming aluminum

January 30, 2017 | By Steve Benson

When choosing tools to bend aluminum, as always, you need to consider the naturally floated radius as well as where the bend turns sharp. You also may consider forming certain aluminum grades in the annealed condition.

Software solves the biggest bending problems for tube fabricators

January 20, 2017 | By Tom Adams

CAD software allows engineers to work up perfect designs, and this is problematic for tube fabricators. If the engineer lacks experience with tube, they tend to develop parts that can't be made, or can't be made economically. Unison has introduced software to deal with this situation.

What makes an air bend sharp on the press brake?

November 16, 2016

Press brake operators use rules of thumb when it comes to determining sharp bends. But what truly determines the point at which a bend turns sharp is the relationship between the punch nose radius, the tonnage required to form, and the shear strength of the material.

Applying sheet metal forming principles to plastic

July 12, 2016 | By Steve Benson

Anytime the inside radius or material thickness varies, there will be a change in the bend deduction. This is just as true when bending plastic as it is when bending sheet metal.
