The die casting process involves the use of a furnace, metal, die casting machine, and die.
The metal, typically a non-ferrous alloy such as aluminium or zinc, is melted in the furnace and then injected into the dies in the die casting machine. After the molten metal is injected into the dies, it rapidly cools and solidifies into the final part, called the casting parts.
The castings that are created in this process can vary greatly in size and weight, ranging from a couple of ounces to 100 pounds. One common application of die-cast parts are housings - thin-walled enclosures, often requiring many ribs and bosses on the interior.
