Cold heading machine vs cold forming machine

Cold heading machines and cold forming machines are both used in the production of metal components but differ in their specific applications and processes.

Cold heading process vs cold forming process

Cold heading: In cold heading, a machine uses a series of dies and punches to transform a metal blank into a finished part by exerting high-pressure force. The process involves cutting a slug from a coil or wire and then forming it using a chain of hammers and dies.

Cold forming: Cold forming is a broader term that encompasses various metal forming processes without the use of heat. It includes processes such as swaging, bending, forging, and extrusion. Cold forming techniques shape the metal part with force, pressure, or mechanical deformation, often utilizing rolling, drawing, or pressing.

Cold heading machine application vs cold forming machine application

Cold heading machine: Cold heading machines are commonly used for the mass production of small to medium-sized parts such as screws, bolts, rivets, and other fasteners. They are ideal for producing high-volume, intricately shaped parts with tight tolerances.

Cold forming machine: Cold forming machines are generally used for larger parts such as gears, shafts, and other components where intricate shaping and greater mechanical strength are required2. Cold forming processes are advantageous for producing parts with improved mechanical properties, reduced material waste, and cost-effectiveness.

Speed and Automation:

Cold heading machine: Cold heading machines, also known as cold headers or part formers, operate at high speeds and can transform a wire into a complex-shaped part with high accuracy and repetitive tolerances. These machines can achieve speeds up to 400 pieces per minute.

Cold forming machine: Cold forming processes are typically performed at lower speeds compared to cold heading machines, as they often involve more intricate shaping and require slower and controlled forces for the desired deformation.
