Die casting is a one of a manufacturing process that can produce geometrically complex metal parts through the use of reusable molds, called dies. This process involves the use of a furnace, metal, die casting machine, and die. The metal, typically a non-ferrous alloy such as aluminum or zinc, is melted in the furnace and then injected into the dies in the die casting machine. There are two main types of die casting machines – hot chamber machines (used for alloys with low melting temperatures, such as zinc) and cold chamber machines (used for alloys with high melting temperatures, such as aluminum). After the molten metal is injected into the dies, it rapidly cools and solidifies into the final part, called the casting.
