Casting is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process.
The casting process is as follows：
Centrifugal casting (industrial) – A casting technique that is typically used to cast thin-walled cylinders
Investment casting – industrial process based on lost-wax casting
Lost-wax casting – Process by which a duplicate metal sculpture is cast from an original sculpture
Sand casting – Metal casting process using sand as the mold material
Die casting – Metal casting process that is characterized by forcing molten metal under high pressure into a mould cavity
Glass casting – Process in which glass objects are cast by directing molten glass into a mould where it solidifies
Lost-foam casting – Type of evaporative-pattern casting process
Plaster Casting (Processs) - Sand casting process with use of Plaster to fill gaps
Molding (process) – Shaping a liquid or plastic material by making it conform to a more rigid mold
Casting materials include steel, stainless steel, carbon steel, alloy steel; iron, gray iron, ductile iron; aluminum, aluminum alloy; copper, brass, alloy, etc.
