Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand—known as casting sand—as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries. In 2003, over 60% of all metal ...
An engine block with aluminum and magnesium die castings. Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process.
The die casting process forces molten metal under high pressure into mold cavities (which are machined into dies). Most die castings are made from nonferrous metals, specifically zinc, copper, and aluminium-based alloys, but ferrous metal die castings are possible. The die casting method is especially suited for applications where many small to ...

For the production of gray iron, ductile iron and steel castings, sand casting remains the most widely used process. For aluminum castings, sand casting represents about 12% of the total tonnage by weight (surpassed only by die casting at 57%, and semi-permanent and permanent mold at 19%; based on 2006 shipments). The exact process and pattern ...
Compared to the two main competing processes, injection molding and (zinc) die-casting, spin casting has significant advantages in terms of startup cost and ease of use. In some cases, spin casting can also be an alternative to sand casting, plaster mold casting or investment casting. These three techniques (sand, plaster and lost wax) are not ...
V-process casting – Vacuum with thermoformed plastic to form sand molds. No moisture, clay or resin required. Die casting – Metal mold. Billet (ingot) casting – Simple mold for producing ingots of metal, normally for use in other foundries. Loam molding – a built up mold used for casting large objects, such as cannon, steam engine ...
