A new die-casting process, such as precision die-casting technology invented by General Dynamics, and semi-solid die casting. High pressure injection results in a very fast filling of the mold so that the molten metal can fill the entire mold before any part solidifies. In this way, surface discontinuities can be avoided even in thin-walled sections that are difficult to fill.
