Yiming Essebi Machinery Equipment Limited

5-Die 5-Blow Cold Heading Machine represents a highly advanced level of cold forming technology, designed to produce extremely complex and precise parts. This type of machine is particularly useful in industries where the demand for high-quality, custom-shaped components such as fasteners, automotive parts, aerospace components, and more is paramount.

The cold heading process is carried out at room temperature and can produce high-density and high hardness bolts. The process is simple and cost-effective, making it suitable for large-scale production. However, it is prone to surface cracks and internal bubbles, requiring multiple surface treatments.
On the contrary, the hot forging process is carried out at high temperatures, which can eliminate residual stresses in the material, improve the fatigue resistance of bolts, and ensure stable material properties. But the process is complex, the manufacturing cost is high, and the heating and cooling processes may cause deformation and discoloration. Therefore, when choosing a process, factors such as product requirements and production costs need to be considered.

Cold heading is suitable for small and medium-sized bolts, such as mechanical and electronic equipment fasteners;
Hot forging is suitable for large-sized, high-strength, and high-quality bolts, such as equipment components for nuclear power, aircraft, automobiles, and ships. Overall, the cold heading and hot heading processes for titanium alloy screws have their own advantages, and the choice of process should be balanced according to actual needs.
