Die casting is a fast, cost-effective manufacturing process for production of high volume, net-shaped, tight tolerance metal components. It has the benefit of increased quality and repeatability, often at lower costs compared to other processes.

The die casting process is the injection under high pressure into a steel mould (or tool) of a molten metal alloy, which solidifies rapidly (from milliseconds to a few seconds) to form a net shaped component and is then automatically extracted. The die casting tool will typically produce any number of components from hundreds of thousands to millions, before requiring replacement .
