... starts from a nondendritic solid precursor material that is specially prepared by a manufacturer, using continuous casting methods. Upon reheating this material into the mushy (two-phase) zone, a thixotropic slurry is formed, which is the feedstock for the semisolid casting operation ( Fig. 4 ). Fig...

... Abstract Thixomolding is a method of molding thixotropic semisolid magnesium alloy pellets in a machine that resembles an injection molding machine in physical appearance and operation. This article describes the process of thixomolding. The use of hot sprues and hot runners in the thixomolding...
