What Is Cold Heading? An Overview 2023

Cold Heading VS Hot Heading

Cold heading is a manufacturing process that processes metal raw materials (usually linear) into fasteners at room temperature. We commonly use cold heading machines to produce bolts, screws, nuts, rivets and other fasteners. Cold heading machines usually include dies, punches and blank holders.

Today’s blog will start from the following aspects: the concept of cold heading, processing technology, materials used, comparison between cold heading and hot heading, deformation methods and their advantages.

Cold Heading VS Hot Heading

Cold heading is a process that uses impact force to form metal into a specific shape in a mold at room temperature. It produces almost no excess waste, does not require heating, consumes less energy, and does not require a cooling process. The production speed is fast and can reduce Cost of production. However, most of them cannot be processed at one time, and they often have to be extruded in different molds in sequence, and the hardness requirements of the materials cannot be too high.

Cold heading is often used to manufacture fasteners and connections, as well as other metal parts that require high strength. It is usually used for mass production.

Hot heading involves heating and softening the material during metal processing, and then plastically deforms it by impact force. Hot heading can better change the internal structure and performance of metal materials and reduce process difficulty. However, it requires a large amount of investment in heating equipment and energy, produces more waste materials during the production process, and has higher production costs.

Hot heading is usually used to manufacture complex, high-precision parts, such as automotive engine parts, aerospace engine parts, etc., and is usually not suitable for mass production because the heating and cooling processes require more time.
