Semi-solid metal casting
Modified form of die casting process
Semi-solid metal casting (SSM) is a near net shape variant of die casting. The process is used today with non-ferrous metals, such as aluminium, copper, and magnesium. It can work with higher temperature alloys that lack suitable die materials. The process combines the advantages of casting and forging.The process is named after the fluid property thixotropy, which is the phenomenon that allows this process to work. Thixotropic fluids flow when sheared, but thicken when standing. The potential for this type of process was first recognized in the early 1970s. Its three variants are thixocasting, rheocasting, and thixomolding. SIMA refers to a specialized process to prepare aluminum alloys for thixocasting using hot and cold working.
