Cold-beaten parts, usually refer to parts that are manufactured by the cold heading process. This process is very common in metalworking, especially in the manufacture of standard parts and fasteners such as nuts, bolts, shafts, etc. The main characteristics of cold-beaten parts include:
1. High Strength: Due to the strong extrusion of the material in the cold state, the grain refinement makes the mechanical properties of the final product improved, especially the strength.
2. **High dimensional accuracy**: high dimensional accuracy can be achieved in the cold heading process, which reduces the need for subsequent processing and reduces the cost.
3. **Good surface quality**: The extrusion effect in the cold heading process can make the surface of the product smoother, reduce burrs and improve the service life.
4. **High material utilization**: Compared with machining, the cold heading process can effectively use raw materials and reduce waste.

5. **High production efficiency**: Cold heading is a continuous production process, suitable for large-scale production, which can significantly improve production efficiency.
6. Cost-effective: Although the initial equipment investment may be large, due to its high efficiency and low material loss, the cost-effectiveness of cold-beaten parts is higher in the long run.
7. Limited Shape Complexity: Although cold heading technology is constantly advancing, it is difficult to achieve very complex geometries compared to hot working.
Because of the above advantages, cold-beaten parts have a wide range of applications in the machinery manufacturing industry.
