The cold heading process is a common method for manufacturing the heads of fasteners such as bolts, screws, pins, and rivets. Often, what we refer to as "heading" is actually a type of cold heading. Cold heading is a forging method that uses a mold to compress metal bars at room temperature.

The specific operation process is to place the metal bar into the cold heading machine and squeeze it under pressure to form. During the squeezing process, the metal bar undergoes plastic deformation, thereby changing its shape and size, and the head of the fastener is formed.

In the field of fastener manufacturing, the cold heading process is widely used because it has the following characteristics:

The cold heading process can be carried out at room temperature without heating the metal material;

The cold heading process can reduce or replace cutting processing, improving material utilization;

The models and series of cold heading machines are complete, suitable for the formation of various bolts and nuts, with reliable equipment performance, high efficiency, and stable quality;

The cold heading machine can achieve continuous, multi-station, and automated production, with simple operation and suitable for mass production;

The cold heading process can improve the surface finish of the workpiece and ensure the accuracy of the workpiece, and can manufacture high-precision and high-strength bolts, nuts, etc.;

The cold heading process can improve the mechanical properties of the workpiece, such as increasing the density and hardness of the material, thereby enhancing wear resistance and corrosion resistance. Overall, the cold heading process can increase productivity, ensure the quality of fasteners, reduce material waste, and lower production costs. It is being increasingly applied in the production of standard fasteners.
