Cold heading machine companies specialize in the design, manufacturing, and distribution of cold heading machines.

Cold forging is a metal shaping & manufacturing process where a metal bar or billet is shaped by applying pressure at room temperature or below its recrystallization temperature. During cold forging, the plastic deformation of metal causes an alteration in its shape.

The benefits of cold forging include efficiency, as it requires less time compared to other forging methods. It also provides a superior surface finish, precise shaping, and improved dimensional control. On the downside, its application is limited to simpler shapes, and it’s more likely to cause work hardening, making the material more brittle and less ductile.

In contrast, hot forging involves the deformation of metals at temperatures above their recrystallization point. Though it allows manufacturing more complex shapes and larger parts, it tends to result in a poorer surface finish and less precise control over dimensions.

The metals commonly used in cold forging methods include steel, stainless steel, copper, brass, and aluminum. These are often selected due to their good formability at room temperatures. From a machinery perspective, equipment like forging presses, mechanical press, and hydraulic presses, are commonly used.

Cold forging finds a wide range of applications across various industries. In the automotive industry, it’s used to produce parts like axles, gears, shafts, and bearings. In the aerospace industry, cold-forged parts include fasteners, rivets, and other structural components. Various electrical and hardware industries also extensively use cold forging.

Therefore, cold forging is an efficient and precise method of metal shaping, despite some limitations, and finds wide-ranging industrial applications.
