The new spinning process for pressure vessel heads eliminates the need for traditional stamping and numerous molds, saving materials and energy, improving production efficiency, and producing high-quality heads. Some domestic manufacturers have already introduced this technology and are currently piloting spinning machines for pressure vessels.
Hot spinning is a hot research topic. Compared to hot stamping, it offers advantages such as no need for expensive molds, high adaptability, low cost, controllable final spinning temperature, good quality control, and high dimensional accuracy. The process involves simultaneous local heating and spinning. Stress analysis of different types of pressure vessel heads can be performed using ANSYS Workbench software.
