Cold bending machines have the characteristics of high efficiency, high precision, and high automation, and are widely used in manufacturing industries such as construction, automobiles, machinery, and ships. Compared with traditional hot bending processes, the profiles processed by cold bending machines have better physical and mechanical properties, corrosion resistance, and low energy consumption and processing costs. With the development of industrial technology, the application scope of cold bending forming machines will be further expanded, and their technical performance and processing accuracy will continue to improve.
