What Is Cold Heading?

Heading is a metalworking process that incorporates the forging, extruding, and upsetting processes. The heading is often performed in cold conditions, resulting in cold working. So in this passage, we will talk about cold heading.

What is cold heading?

Cold heading, also called cold forming, is a manufacturing process for changing the geometry of metal parts by using high speed and pressure, forcing metal into the shape of the die used. Cold heading manufacturing is a multi-step process used to form metal parts at room temperature. Unlike other metal fabrication processes, hammers and dies are used at a high speed to form the metal without heating the material. Cold heading stars with coiled wire or rod made in steel, stainless, copper, aluminum, brass, or some other materials. These wires and rods will be fed into a cold heading machine. The wire is automatically cut to a pre-determined length, partially inserted into a die, and upset to form the head or another feature, such as a round shoulder.?

Advantages of cold heading

Using a cold heading process can reduce the part cost both through production speed and then minimal scrap generated from a cold-headed part. As the part is formed but not cut, the grain flow stays intact and creates a much stronger part for its size.

Usage of cold heading

The cold heading can be used to form a variety of shapes, including the most commonly for heads of screws. Cold heading has played a critical role in fasteners and has been widely used in automotive production, manufacturing, aviation, and 3C, including computer, communication, and consumer electronics.

Application of cold heading dies

The cold heading die is mainly used for all kinds of metal and non-metal powder pressing and stamping, steel bar, steel pipe stretching with large compression rate, top forging, perforation, and stamping die, machine accessories, die core, production of stamping die, such as stamping watch parts, musical instrument spring sheet, and so on. The tungsten carbide dies are used as the mold of the battery shell and the toothpaste shell; Stamping dies for small-size steel balls, screws, and nuts, impact-resistant forging dies and red stamping dies, cold heading, cold stamping, and cold pressing dies for standard parts, bearings, tools, and other industries; Stamping die for a warhead and cartridge case, etc.
