Die casting is the process in which molten metal is forced into a mold cavity with high pressure. Using molten metal requires tooling that is made of hardened tool steel,which causes start-up costs for new programs to be extremely expensive and lengthy. Tools also wear quickly,requiring expensive refurbishments and replacements throughout the life of the tool or product lifecycle. Ferrous metals,like carbon steel and stainless steel,cannot be cast using this method,further limiting its usefulness.
Investment casting methods injects wax into an aluminum cavity. Aluminum has a lower metal fabrication cost,is easier to cut,and less expensive to maintain. Using wax also is easier on tooling,allowing it to maintain consistent parts for many more uses. Investment casting allows for ferrous and non-ferrous metals (aluminum,brass,bronze,etc) to be cast.
