The main advantages of cold heading technology

Cold heading is carried out under normal temperature conditions. Cold heading can improve the mechanical properties of metal parts.

2. Cold heading technology can improve material utilization efficiency. Taking cold heading bolts as an example, the new process of "concave hole" hexagonal head bolts can achieve a material utilization rate of over 99%. Except for the loss of material heads and tails, it has achieved complete zero cutting processing. If cutting is used, the material utilization rate is only 40%. The material utilization rate of cold heading nuts can also reach about 80%, while the material utilization rate of cutting nuts is only 54%.

3. Cold heading technology can greatly improve productivity. Compared with the original cutting process, the productivity of cold heading nuts is increased by about 25-30 times.

4. Due to the use of multi station cold heading machines, each process can be processed simultaneously on one machine tool, thereby reducing equipment investment, minimizing the production space occupied by equipment, reducing the transportation of semi-finished products between processes, especially reducing the labor intensity of workers and improving working conditions.

5. Cold heading technology can improve the surface smoothness of products and ensure product accuracy. The general smoothness can reach V5, and special requirements can reach V6. For mass production of bolts, nuts, etc., their accuracy can be fully guaranteed.

Cold heading technology is increasingly widely used in mechanical manufacturing, especially in the production of standard fasteners, due to its high productivity, good product quality, greatly reduced material consumption, lowered production costs, and improved working conditions. Among them, the most representative products produced by multi station cold heading machines are bolts, screws, and nuts.
