Articles | What You Need to Know About Aluminum Die Castings

Often times, it is very ordinary to see parts containing materials made from die castings. From lighting fixtures to vehicle parts, die casting has something to offer. Be it simple, tiny parts or big, complex accessories, die casting can mold thousands of stuff made from metal and other applicable materials distributed commercially and industrially.

What is Aluminum Die Cast Parts Company? Die casting is a metal forming process that injects metal into a strong, high-pressured steel mold or die producing accurately engineered metal parts. This process solidifies the molten metal quickly. As soon as the metal hardens, the part is ejected from the die. Die casting is almost the same as permanent mold casting with results characterized by precise dimensions, sharp definition, and high repeatability. It is a versatile process enabling the manufacture of a wide range of durable finishes.

History of Aluminum Die Casting Parts Company. In 1838, the first manually-operated die casting machine was invented for the purpose of manufacturing movable type for printers. The first patent of this model was awarded to Sturges in 1849 for mechanized printing type production. For almost twenty years, this die cast equipment was solely used to make printer types. But by the end of the century, several commercial applications for die cast were discovered, namely: parts for cash registers and phonographs among others. Since then, many other types of equipment for die castings were made to produce many other metal tools.

Production Equipment. There are two types of machines used for die casting: the hot chamber machine and cold chamber machine. Hot chamber machines, also known as gooseneck machines, normally process metals such as copper, lead, zinc, magnesium, and other low melting point materials that work well with metal pots, plungers, and cylinders. It has a compartment which contains molten metal. This molten metal is then poured towards the furnace through a connecting metal called a gooseneck. Once the molten metal fills the gooseneck, the piston pushes the metal into the die. Cold chamber machines, on the other hand, processes high melting point alloys such as aluminum and others. Here, the molten metal is dispensed to a cylindrical sleeve, or a cold chamber using a manual or automatic hand ladle. The hydraulic plunger shoves the metal into the locked die at a very high pressure.

Alloys Used for Die Cast Parts Production. Die castings make use of non-ferrous or non-iron materials such as zinc, aluminum, magnesium, copper, lead, tin, and bronze. It is also reasonable to die cast iron but it is an infrequent practice. Below is a short description of the three most popular metals used in die casting: http://www.castings-aluminum.com/technical.html

Zinc : Zinc is ductile and perhaps the easiest metal to cast and plate. It is highly recommended for small parts and promotes long die life.

Copper alloy: Copper is a strong metal with high wear and corrosion resistance. Among other metals, it exhibits excellent dimensional stability and mechanical properties of alloys.

Aluminum alloy: Aluminum has good mechanical properties and corrosion resistance. It exhibits high thermal and electrical conductivity making it resilient to extremely high temperatures. It is perfect for making thin walls and complex shapes.
