Thixomolding^[1]

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 is discussed. The article provides information on thixoblending and summarizes results from two independent studies of the mechanical properties of recycled AZ91D. It also describes the factors on which the mechanical properties depend and illustrates microstructures of semisolid thixomolded AZ91D.
