The characteristics and environmental aspects of magnesium thixomolding versus die casting process

Magnesium is an increasingly popular metal used in the design of lightweight constructional components. The applications in the automobile and electronics sector are rising in the past several years. The common magnesium production technology is die casting. One of the advanced manufacturing processes for magnesium is thixomolding. The thixomolding process is applied to the metal in semi-solid state. This paper describes the underlying chemical and physical phenomena of thixomolding, the technical process and machinery, the characteristics of the produced workpieces, and different applications of thixomolded parts. The number of thixomolding manufacturers by different regions and recent years is presented and an outlook on future developments is given. Thixomolding is compared to die casting, which is the prevailing technology for magnesium processing. The difference in energy consumption is presented, as well as the cost of the used amounts of gasses. The environmental impact of different gasses used, expressed as the CO2-equivalent or the gasses’ toxicity is presented. Some gasses used in die casting have a strong environmental imprint: sulfur hexafluoride is a very potent greenhouse gas ; sulfur dioxide is a well-known air pollutant and also corrosive for the equipment and hydrofluorocarbon HFC-134a has a high global-warming potential. On the other hand, the thixomolding process uses the inert gas argon, without a global warming potential.
