Process of gravity casting
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.
