A cold header machine, also known as a cold forming machine or a cold heading machine, is a type of machine that is used to form metal parts from wire or rod stock without the need for heat. Cold heading is a process of forming metal parts by applying pressure to the material using a series of dies and punches.
In a cold header machine, the wire or rod stock is fed into the machine and then clamped in place. A series of punches and dies are used to shape the material, creating the desired form of the part. The process is carried out at room temperature, which is why it is called "cold" forming.
Cold header machines are used to produce a wide range of metal parts, such as bolts, screws, pins, rivets, and other fasteners. They are often used in industries such as automotive, aerospace, and construction, where high-quality and precise metal parts are required. Cold heading is a cost-effective and efficient process that produces parts with excellent strength and durability.
