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.
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.

Can i use high impact polystyrene for lost foam casting?
No. High impact polystyrene is a very hard plastic. If you tried doing a lost-foam casting you'd just make a mess.You make a lost-foam casting by creating a styrofoam model of your finished piece, packing casting sand around it to create a mold, then pouring metal into the mold. When the hot metal touches the foam, it vaporizes.You could make your model out of high impact polystyrene then use that to create a cope and drag mold.
Expendable pattern is usen in which type of casting?
Expendable pattern is used in Investment Casting process. It consists of Polystyrene foam and the process known as Lost Foam Process. An intricate design is made of polystyrene foam with help of hand tools or injection molding type process and allowed to enclosed by sand as in other sand molding, then directly molten metal is poured in to the mold without removal of pattern instantly the pattern burns and the molten metal fills the cavity. By this process an intricate shape object can be cast. As, the foam is not been reclaimed it is known as Lost Foam Process.
In what industries is aluminum casting generally used?
Castings are generally sound, provided that the alloys used exhibit good fluidity. Aluminum is one of the few metals that can be cast by all of the processes used in casting metals. These processes, in decreasing order of amount of aluminum casting, are: die casting, permanent mold casting, sand casting (green sand and dry sand), plaster casting, investment casting, and continuous casting. Other processes such as lost foam, squeeze casting, and hot isostatic pressing are also mentioned.
Where can one find information about lost wax casting?
Information about lost wax casting can be found on the wikipedia free encyclopedia website labeled as lost-wax casting. The process is more commonly known as investment casting in its modern version.
What is gravity die casting?
It is process of making Alu. zinc component die. and material flows in die by Gravity force only no external pressure applied as Pressure Die Casting. Gravity casting is the liquid metal in the Earth's gravity into the casting process, also known as gravity pouring casting. The generalized gravity casting include sand casting, metal casting, investment casting, lost foam casting, clay mold casting; narrow-defined gravity casting refers to the metal casting. uses the force of gravity, to fill a permanent mold, or die, with molten material. It does not use the high-pressure method to form the casting. It will ensure that there will not be any clusters formed during this gravity casting process. The method has advantages like cost effective, good quality, and process control over other casting techniques.

What is the Magnetic moulding process?
magnetic moulding, is an innovative process in which an expendable model is used that is surrounded by metallic particles bonded together by the action of an induced magnetic field. Once the cast metal has solidified the magnetic field is interrupted so that he would collapses by itself, the part is recovered and the particles can be reused in the subsequent castings. The innovative process combines the advantages of the lost foam process and the permanent mould processes; it is environmentally friendly, cost competitive and suitable to produce high quality parts with very complex shapes with a large range of sizes and materials. The components produced do not need any parting lines and the metallurgical and mechanical properties obtained are better than those obtained in lost wax, lost foam and sand casting due to the fine grain structure obtained through the fast solidification phase derived from the use of the metallic particles that form the mould. The potential impact of the new foundry technology is therefore large as it will enable European sand casting and investment casting foundries to offer complex shaped parts with high metallurgical quality through a knowledge based foundry process. The concept on which the magnetic moulding is based was born in Europe together with the lost foam process concept. The maturity of the lost foam process and the results from the investigations in the magnetic moulding concept of the last years finally makes it possible now to approach the proposed project to develop the new foundry process up to the industrialisation stage. The two RTD performers in the group have experience in the lost foam process and one of them has already had the first positive experiences in the magnetic mould concept at lab scale.

What is the first existing monumental work made through lost wax casting technique?
The first existing monumental work made through the lost wax casting technique is generally considered to be the bronze "Charioteer of Delphi," dated to around 470 BC. This ancient Greek sculpture showcases the mastery and precision of the lost wax casting method in creating intricate details and realistic forms.
What was the cire perdue process?
The cire perdue process was a sculpting technique in which sculptures were made by casting wax models using molten metal. It is also known as lost-wax casting.
