What is the Hardest Shape in Wireforming?

August 16, 2013 | Custom Wire Baskets

Wire forms with compound bends typically are the most challenging. A compound bend is a feature within the wire form that has two adjacent bends or generations with no straight length tangent to the beginning and end of those radii.
Marlin Steel wireform 00804001Forming wire is done in a progressive manner, which means when a bend is started, a portion of straight length is required to begin. Typically, 1 to 1.5 times the respective wire diameter is required. There are always exceptions and it must be defined on a case-by-case basis, but this is generally the rule of thumb.
The ability to form a difficult shape ultimately comes down to the operator knowing the machine, its programming capability and the tooling. A skilled operator, for example, can use a grinder to create a little more clearance between compound bends.
