Cold heading technology has outstanding comprehensive advantages in terms of economy, efficiency, performance and environmental protection, and has become the mainstream technology for manufacturing modern standard parts and irregular fasteners.
Extremely High Material Utilization: Cold heading is a near-zero-cutting process, achieving a material utilization rate of 85%–99%, far exceeding that of cutting processes (typically only 40%–54%).
Significantly Increased Production Efficiency: Multi-station cold heading machines can perform multiple processes simultaneously, achieving a production efficiency 25–30 times higher than cutting processes. High-speed models can reach over 300 pieces/minute.
Superior Mechanical Properties: During cold heading, the metal fibers remain continuous and uncut, forming a streamlined structure, accompanied by work hardening. This increases tensile strength by 10%–30% and significantly extends fatigue life.
Suitable for automation and mass production. Cold-forged parts are mostly symmetrical structures, facilitating high-speed, fully automated production with a defect rate as low as 0.8%.
Energy-saving, environmentally friendly, and low-cost. Room-temperature forming requires no heating, resulting in low energy consumption; reduces cutting waste, aligning with green manufacturing trends; and lowers unit cost by over 40% compared to machining.
