1、 Internal high-pressure forming technology:
The internal high-pressure forming technology is a new technology in recent years, which can greatly improve the processing efficiency and effect when applied to the shell processing. According to their structural characteristics, various connectors can be formed in one step using internal high-pressure forming, or they can be made into profiles using general extrusion methods, and then corrected using internal high-pressure forming. The tube blank is pressed into the mold cavity through internal pressure and axial force replenishment to form it.
