Die casting is a metal casting process that utilizes the inner cavity of the mold to apply high 

pressure to the melted metal. Molds are usually made from alloys with higher strength, and this 

process is somewhat similar to injection molding. Most die-casting castings are free of iron, such 

as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Depending 

on the type of die-casting, it is necessary to use a cold chamber die-casting machine or a hot 

chamber die-casting machine.
