Greensand is a mixture of silica sand, clay, other additives & moisture. Note: There are two types of sand used in the casting process that are green sand & dry sand.

We will fill the sand tightly in the drag.

After that, we will put the drag above the wooden box and fill the drag with the sand. To make the mold we take a wooden box, and then place the pattern in the wooden box. Now after making the core comes the mold making. The core is made from the sand of higher purity. The core is made when the casting requires some internal features like a hole. Core Forming:Īfter making the pattern then comes the core making. The dummy material can be made of wax, wood, metal, plastic, etc. The dummy material is also called the pattern. Then we have to make the dummy material of that equipment that we have selected to cast. The First step of this process is to select the shape that we have to cast. There are five steps involved in the casting process:

Parting Line: This is the line that separates the cope and drag.

Sprue: It is the cavity through which molten metal flows downward.

Pattern: It is the duplicate of the shape needed to form.

Pouring Cup: It is the cup or basin from where molten metal is poured in the metal.

Runner: It is the passage from where the molten metal can be regulated before reaching the mold cavity.

Riser: It is the reservoir of molten metal that supplies additional metal in case of any reduction.

Mold cavity: This is the hollow space in the mold where the metal part is formed.

Vents: These are the places created in the mold to carry off-gases produced when the molten metal comes in contact with the sand.

Core: Core is used to create an internal hollow cavity in the final product.

Drag: The lower half of the flask is called drag.

Cope: The upper half of the flask is called cope.

Flask: A metal or wood frame in which mold is formed.
