In the second phase of the clay modelling workshop organised at Indira Gandhi Rashtriya Manav Sangarahalaya (IGRMS), Modeller Pramod Kumar Sharma, about Mold making and casting said that 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. Molding is the process of manufacturing by shaping liquid or pliable raw material using a rigid frame called a mold or matrix.
Sanjay Sapre, Modelling Assistant told that when a sculpted model has been completed, reproductions of the piece for display. To make the reproduction, a mold and cast of the model must be made in one of a variety of casting mediums, such as plaster, bronze. A mold is the negative or hollow cavity produced around a sculpted piece for use in creating multiples of that piece.
DC Manna Modelling Artist said that A cast is the positive or reproduction of the original piece of sculpture created by pouring casting material into a pre-formed mold.
