Die casting is a precision casting method that uses high pressure to force molten metal into a metal mold with complex shapes. It is characterized by using the cavity of the mold to apply high pressure to the molten metal. Molds are usually machined from stronger alloys, a process somewhat similar to injection molding. Most die castings 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. Die casting is especially suitable for the manufacture of a large number of small and medium-sized castings, so die casting is the most widely used one in various casting processes. Compared with other casting techniques, die casting has a flatter surface and higher dimensional consistency.
