There are two molds that you put together to make the casting, so the part is easier to get out of the mold ----------------- If two or more (sets) of molds were necessary to produce the casting. Picture a statue, one mold was used to create the body and a second mold was used to create an outstretched arm, that is attacted separately.

What is meant by gravity die casting?
Casting is a manufacturing process by which a molten material such as metal or plastic is introduced into a mold, allowed to solidify within the mold, and then ejected or broken out to make a fabricated part. Casting is used for making parts of complex shape that would be difficult or uneconomical to make by other methods, such as cutting from solid material. Die Casting, (outside the USA is also known as Permanent Mold Casting) , is a process in which the molten material is forced into a steel mold or die casting die. This process is usually accomplished by using high pressure injection systems. Permanent molding in the USA, is another form of gravity casting using an iron mold. Gravity Die Casting uses the force of gravity, instead of high pressure means, to fill a permanent mold, or die, with molten material.
What is the definition of foundry technology?
Foundry is a technology of casting metals into shapes by melting them into a liquid, pouring the metal in a mold, and removing the mold material or casting after the metal has solidified as it cools.
What is the difference between die casting and pressure die casting?
In sand mold casting the molten metal is poured in to the mold cavity , while in pressure die casting the molten metal is forced under high pressure in to the cavity. The sand casting process is used for small batch production where pressure die casting is used for mass production.
Difference between die casting and sand casting?
Sand Casting-is a cast part produced by forming a mold with the help of a model or pattern pressed into a sand mixture and then removed. Die Casting- is the process of forcing molten metal under high pressure into mold cavities (which are machined into dies).
Which industry uses centrifugal casting?
Centrifugal casting is used in Silversmithing industry. The molten metal is being poured or sprayed to the sides of the spinning mold which forms a centrifugal casted metal.
