A cold heading machine is an industrial tool that shapes metal parts at room temperature, typically producing items like bolts, nuts, and rivets. It can be categorized by its processing method—single-strike for simple shapes or multi-station for complex forms; drive mechanism—hydraulic for powerful operations or mechanical for efficiency; and automation level, ranging from manual to fully automatic for high-volume production. Additionally, these machines are tailored for specific materials, such as non-ferrous metals or steel, and can have horizontal or vertical configurations depending on the application requirements and workspace layout.
