Abstract
Processes for die casting metals are provided, which are more energy efficient and less expensive than the current metal die casting processes. The die casting processes discussed herein utilize a water-soluble die release fluid and hydraulic equipment which uses water-insoluble hydraulic fluid. By doing so, the hydraulic fluid and die release fluid present in the waste collected from the die casting process can be collected via separation techniques. One or both of the collected hydraulic fluid and die release fluid may then be re-used in the same die casting process, another die casting process, or other processes altogether.
