An overall review is given concerning fundamentals,numerical simulation, machine and process in the field of internal high pressure forming in China. Some research results are introduced in detail, including axial buckling stress, bursting pressure, control and use of wrinkles, key technology of hydroforming machine and major factors affecting simulation results. Typical prototype parts manufactured by internal high pressure forming are shown such as structural components, special shape pipes, hollow shafts and assembled camshafts. Finally, the trends in internal high pressure forming are discussed.
