Abstract：

A new press forming technology,viscous pressure forming(VPF),is briefly introduced.By comparative analysis of VPF,using viscous media for flexible punch,and hydroforming(HF),using water for flexible die,some process characteristics in VPF are received,and the application of VPF in vehicle manufacturing is analyzed.
