Die casting allows for uniform manufacturing of machine parts with long lasting service in mind. The machine can create any size, shape, and/or characterization quickly. The mold can be very complex and is capable of integrating assembly features like screws, rivets, or drill holes. Casting can use any number of alloys for any type of industry. These industries include automotive, communications, electronics, and consumer appliances just to name a few. The quality of metal used is much stronger than plastic molded parts. These metals have moderate to high fatigue strength, high conductivity, and corrosion resistance. During the casting process pressure tightness within the mold reduces trapped gasses in the liquid metal. The use of metal and elimination of gases creates strong solid parts. Disadvantages of casting process are porosity (measure of empty spaces), high setup cost, large production volume (cost effectiveness), and the use of non-hot chamber alloys like aluminum, magnesium and copper.
