Abstract
The Giga-casting process, proposed by Tesla, has become a transformative technology with great potential for improving the lightweighting of super-sized complex thin-walled vehicle parts. Recently, the application of lightweight alloys, especially Al alloys, in the vehicle industry is gradually expanding, but there are fewer reports reacting to super-size Al alloy parts. The overall goal of this paper is to provide a detailed summary of the development and advancement of the revolutionary giga-casting technology. This paper summarizes the development process of die casting Al alloy materials, die casting machines and molds, and discusses the latest research on giga-casting technology in terms of materials, processes, structural optimization, property analysis, and applications. In addition, the whole process development technology route for super-sized castings is introduced through actual production cases to enhance the confidence of companies in developing new parts. Finally, the multiple challenges facing giga-casting technology and how to face them are sorted out. Overall, this paper provides an in-depth discussion of giga-casting technologies, highlighting their potential and future expanded applications in automobiles.
