Plaster mold casting

Plaster casting is similar to sand casting except that plaster of paris is substituted
for sand as a mold material. Generally, the form takes less than a week to prepare,
after which a production rate of 1–10 units/hr·mold is achieved, with items as massive
as 45 kg (99 lb) and as small as 30 g (1 oz) with very good surface finish and close
tolerances.Plaster casting is an inexpensive alternative to other molding processes for
complex parts due to the low cost of the plaster and its ability to produce near net
shape castings. The biggest disadvantage is that it can only be used with low melting
point non-ferrous materials, such as aluminium, copper, magnesium, and zinc.
