Background
Die casting is a metal casting process and is characterized in that high pressure is applied to molten metal by utilizing an inner cavity of a die. The mold is typically machined from a stronger alloy, a process somewhat similar to injection molding. Most die cast parts are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Depending on the type of die casting, either a cold chamber die casting machine or a hot chamber die casting machine may be used. The casting equipment and molds are expensive to manufacture, and therefore the die casting process is typically only used to mass produce a large number of products.
