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.
When do you use solid pattern for casting?
solid pattern is used to create the mould cavity. it is a full size model of a part that makes an impression in the sand.
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.

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.
