Differences between lost foam casting and lost wax casting?

Answer 1

Lost-wax casting sometimes called by the French name of cire perdue (from the Latin cera perduta) is the process by which a metal (such as silver, gold, brass or bronze) sculpture is cast from an artist's sculpture. Intricate works can be achieved by this method, primarily depending on the carver's skills. In industrial uses, the modern process is called investment casting. An ancient practice, the process today varies from foundry to foundry, but the steps which are usually used in casting small bronze sculptures in a modern bronze foundry are generally quite standardized.

Other names for the process include "lost mould," which recognizes that other materials besides wax can be used, including tallow, resin, tar, and textile, and "waste wax process" or "waste mould casting", because the mould is destroyed to unveil the cast item. Other methods of casting include open casting, bivalve mould, and piece mould. Lost-wax casting was widespread in Europe until 18th century, when a piece-mold process came to predominate.

Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material.

It is relatively cheap and sufficiently refractory even for steel foundry use. A suitable bonding agent (usually clay) is mixed or occurs with the sand. The mixture is moistened with water to develop strength and plasticity of the clay and to make the aggregate suitable for molding. The term "sand casting" can also refer to a casting produced via the sand casting process. Sand castings are produced in specialized factories called foundries.

Over 70% of all metal castings are produced via a sand casting process.

Answer 2

Actually there are different types of casting, wax, bronze and foam but I always like the bronze casting. There are a lot of statues were made up of bronze which really looks very nice and attractive too.

Lost foam means that pieces of foam are removed from your mold, while lost wax means that wax is removed from your mold. Wax is easier to work with, but you can only cast it once since wax melts. Foam can probably be used again, but it is harder to work with.

During the modern investment casting manufacturers process, a wax pattern is created and dipped in liquid ceramic, delivering superior dimensionality with minimal machining after the ceramic shell is broken off.

Answer 4

Lost wax casting and investment casting are two names for the same thing
