Precision Cold Heading at Its Best.
7-station cold heading machine is mainly used for mass production of fasteners such as nuts and bolts. Cold heading machine is a kind of equipment specially used for mass production of fasteners such as nuts and bolts. It uses cold heading process to forge bars or wires into products of required shapes. 7-station cold heading machine means that it can process seven stations at the same time, which improves production efficiency and output.
The cold heading process is to apply pressure to the metal bar through the die at room temperature to make it plastically deform, so as to obtain the desired part shape. This process is suitable for the production of parts such as bolts, nuts, nails, rivets and steel balls. The materials can be copper, aluminum, carbon steel, alloy steel, stainless steel and titanium alloy. The 7-station cold heading machine can realize continuous, multi-station and automated production through the multi-station design, which improves production efficiency and product quality consistency.

Cold heading machine is a device that uses the plastic deformation of metal under the action of external force to redistribute the metal volume through the die to form the required parts or blanks. The cold heading process is suitable for the production of standard fasteners such as bolts, screws, nuts, rivets, pins, etc.
Cold heading machines are widely used in the production of various fasteners, especially in large-scale production. Its high efficiency and high precision make it widely used in the fields of automobiles, motorcycles, and basic machinery industries.
