Die casting is a specific branch of the metal casting industry. Metal casting is a manufacturing process where molten metal is poured into a mold to create a solid product. Other branches include sand casting, investment casting, lost foam casting, permanent mold casting, and centrifugal casting. Die casting was created in the mid-19th century starting in the late 1840’s and early 50’s. The man who created the first die cast used it to cast printing type. Of the alloys used for modern die casting, tin and lead were most popular. However, around WWI zinc alloys were introduced. This spurred the creation of copper and magnesium. Improvements to this manufacturing process with the invention of computer technology have furthered the efficiency of all die cast machinery. Over the years these improvements have allowed die casting to be a useful process in many markets. With a total sales of 8 billion dollars in die casted products in 2005. There are two types of die casting manufacturing markets, Captive and Custom. They differ from one another because captive die casters create castings for their own use. A custom caster produces casts for individual customers who use them in their end products.
