The state of the art of metal forming technology is summarized. It is suggested that metal forming technology be based on mechanics of solids and materials science of physics to become a fully science, macro science and micro science should be jointly considered, the theory of metal forming can then fully develop and make a tremendous breakthrough. Computational mechanics and software technology are used to make metal forming process virtualized and visualized. Metal forming processes and equipment are computer controlled by using computer technology and automatic control theories. New metal forming technologies may be developed using new energy resources, new forming mediums and new loading methods. New metal forming technologies are required to be developed for new materials and new products according to the needs of automotive industry, electrical and electric industry and aerospace industry.
