Molten metal before casting Casting iron in a sand mold. In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape.
Throughout history, metal casting has been used to make tools, weapons, and religious objects. Metal casting history and development can be traced back to Southern Asia (China, India, Pakistan, etc). [3] Southern Asia traditions and religions relied heavily on statue and relic castings. [4]
Casting process simulation is a computational technique used in industry and metallurgy to model and analyze the metal-casting process. This technology allows engineers to predict and visualize the flow of molten metal, crystallization patterns, and potential defects in the casting before the start of the actual production process .
Investment casting is an industrial process based on lost-wax casting, one of the oldest known metal-forming techniques. [1] The term "lost-wax casting" can also refer to modern investment casting processes.
Permanent mold casting. Permanent mold casting is a metal casting process that employs reusable molds ("permanent molds"), usually made from metal. The most common process uses gravity to fill the mold, however gas pressure or a vacuum are also used. A variation on the typical gravity casting process, called slush casting, produces
Melting metal in a crucible for casting A metal die casting robot in an industrial foundry. Melting is performed in a furnace. Virgin material, external scrap, internal scrap, and alloying elements are used to charge the furnace. Virgin material refers to commercially pure forms of the primary metal used to form a particular alloy.
