Die casting is a process in which various metals can be cast from molten states into a mold. These molds are called "dies" in many foundry environments. The die is filled with typically non-ferrous metals, such as zinc and aluminum. It is filled in a high-pressure application that ensures that the density of the die-cast material is at the desired level.
The metal is injected into a specific cavity or mold that has been created. This is then machined to create two opposing steel dies. After the cooling process is completed, the casting is then removed from the mold. It is next burred or buffed to create a product that has been manufactured to exact specifications.
