Basically, Cold heading implies putting a material in a die and giving it shape by hammering. This is quite different from the hot forging where the metal is first heated before the forming process takes place. It is also different from casting where the metal is melted first then,
In the last article, we mentioned that due to the strength of steel, cold-formed steel also provides architects with greater flexibility, allowing designs that incorporate longer spans and other architectural features. In this article, we will introduce another three advantages of cold-formed steel: economic sectional characteristics, durability, and variable product length.
The cold-formed steel can be selected according to the force characteristics of the component, and give full play to its cross-section interface characteristics, making it more economical and reasonable. Cold-formed steel features superior chemical and physical qualities that give it a broad range of advantages over other framing materials.

A door track roll forming machine has been designed for producing steel guide rails for roller shutter doors to open up and close down.Rolling shutter door track or guide rails are usually made out of galvanzied steel or cold rolled steel strips with thickness 1.2-2mm and whenever there is a roller shutter door or a sliding door installed, there will be the door track or guide rails.
Cold forming is a forging process in which coiled wire is sheared and moved through a series of tools and die to press it and change its shape. It displaces the working metal and changes its diameter and length and removes some metal through the process of piercing and trimming. How cold form machin
