Plaster casting is a process of creating a three-dimensional object from a two-dimensional mold. It is a popular art form used to create sculptures, figurines, and other decorative items. The process involves pouring a liquid plaster mixture into a mold, allowing it to harden,
Plaster mold casting is a metalworking casting process similar to sand casting except the molding material is plaster of Paris instead of sand. Like sand casting, plaster mold casting is an expendable mold process, however it can only be used with non-ferrous materials. It is used for castings as small as 30 g (1 oz) to as large as 7–10 kg (15–22 lb). Generally, the form takes less than a week to prepare. Production rates of 1–10 units/hr can be achieved with plaster molds.
