Cold Bending Process

Cold bending is a stamping, rotary or roll 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.

Roll Forming Process: 4 Types, Top 11 Design Guide

old roll forming is a kind of cold bending processing, it is an efficient, effective shaping that delivers tight tolerances on complex profiles. It is the process of gradually bending a flat strip or coil of metal into a longitudinal, uniform profile. To get the desired shape, the operator passes the workpieces through a series of mated tool dies.

Cold roll forming is a cold forming process that doesn’t require heating up the metal. High-temperature, specialized equipment isn’t necessary to produce cold rolled shapes.
