Cold Bending Process

Cold bending is a stamping and bending forming process that bends metal plates , pipes and profiles into workpieces with a certain curvature, shape and size.

Theory of the Cold Bending Process

When metallic working materials are bent in cold condition (below their recrystallization temperature), at first an elastic shape alteration takes place, which is replaced by a ductile shape alteration from a certain degree on. If the reshaping capacity is run down, the work piece breaks.

Bent steel components don’t just “walk out” of the rolling mill. Bent steel members are made of straight materials and are bent by your bending company to your requirements.

The bending process does not affect the strength or structural integrity of the steel. When the shape is successfully bent without any buckling or local cracks in the steel, under actual conditions of use, the component will withstand much less stress than that associated with the bending operation. Once the bending is completed, the member can be expected to perform as needed.
