Abstract
This paper describes the process of precision forging of an aluminium-alloy rotor with 23 radial twist blades. Fully-enclosed die forging with isothermal condition was carried out to form the complexity shape rotor. A combined female die was designed to solve the die releasing. Several forming schemes were employed to reduce the forging pressure or to improve the die fill in the experiment. The results indicate that isothermal fully-enclosed die forging can produce the rotor with radial twist blade precisely, reduce the machining time obviously, make the forging flow lines follow its contour and improve the mechanical properties effectively.
