The extrusion forming technology of metals and the rapid development in extrusion industry of China， especially， in the manufacture of heavy or ultraheavy presses in recent decades are reviewed. The basic theories of extrusion technology such as metal flowing behavior， welding process and performance in porthole extrusion， the evolution and accurate control of microstructure and properties are the important foundations of die design， defect prevention and the improvement of product quality， extrusion yield and efficiency， still attracting great attention from researchers. The development and application of novel extrusion technologies are currently the research emphases， which include digitalized die design and manufacture， high performance difficulttowork materials extrusion， isothermal extrusion， integration of bending and extrusion， clad extrusion， etc. In summary， the trends of extrusion technology in future include three aspects: accurate control of the microstructure and size of the products， difficulttowork materials extrusion and lowcost and highefficiency extrusion process.
