Die casting (note that die casting is not simply called pressure casting) is a metal casting process, and is characterized in that a die cavity is used for applying high pressure to molten metal. 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, a cold chamber die casting machine or a hot chamber die casting machine is required, and the cost of the casting equipment and the die is high, so that the die casting process is generally used only for mass production of a large number of products. It is relatively easy to manufacture die-cast parts with low individual cost increments. Die casting is particularly suitable for manufacturing a large number of small and medium-sized castings, so die casting is the most widely used one of various casting processes. Compared with other casting technologies, the die-cast surface is smoother and has higher size consistency.
