is a semi-solid metal (SSM) injection molding process, primarily used for magnesium alloys , that combines elements of plastic injection molding and traditional die casting. It produces high-precision, lightweight parts with thin walls and low porosity by heating metal chips into a thixotropic slurry—a dough-like state that flows under shear stress—before injecting them into a mold.

Thixomolding is a single-step, semi-solid metal forming process primarily used for net-shape manufacturing of magnesium alloy components. Unlike conventional die casting, it does not require melting the metal completely. Instead, magnesium alloy chips are heated into a semi-solid (thixotropic) state and injected into a pre-heated mold. This report details the process mechanics, material requirements, key benefits over competing technologies (die casting, conventional injection molding), and current industrial applications. is a semi-solid metal (SSM) injection molding process,
