Casting types

                                          Sand casting, the most widely used casting process, utilizes expendable sand molds to form complex metal parts that can be made of
nearly any alloy. Because the sand mold must be destroyed in order to remove the part, called the casting, sand casting typically has a
low production rate. The sand casting process involves the use of a furnace, metal, pattern, and sand mold. The metal is melted in the
furnace and then ladled and poured into the cavity of the sand mold, which is formed by the pattern. The sand mold separates along a
parting line and the solidified casting can be removed. The steps in this process are described in greater detail in the next section
                                         Die casting is a manufacturing process that can produce geometrically complex metal parts through the use of reusable molds, called
dies. The die casting process involves the use of a furnace, metal, die casting machine, and die. The metal, typically a non-ferrous
alloy such as aluminum or zinc, is melted in the furnace and then injected into the dies in the die casting machine
