Sand casting is a versatile and widely used method for creating metal parts. This traditional technique involves forming a mold from sand and pouring molten metal into it to create a desired shape. Here, we’ll explore the parts of sand casting and the step-by-step process of how to cast metal in sand.

Key Parts of Sand Casting:

1. Pattern: This is the replica of the part you wish to cast, usually made from wood, metal, or plastic.

2. Mold: Created using sand, it holds the shape of the pattern.

3. Core: Used to create hollow sections in the casting.

4. Pouring Basin: Where molten metal is poured into the mold.

5. Riser: Acts as a reservoir to supply molten metal as the casting solidifies.

How to Cast Metal in Sand:

1. Create the Pattern: Design and construct the pattern based on the final product specifications.

2. Prepare the Sand Mold: Pack sand tightly around the pattern in a flask (a container that holds the mold). Remove the pattern, leaving a cavity in the shape of the object.

3. Insert the Core: If the part requires hollow sections, place the core inside the mold.

4. Pour the Metal: Heat the metal until molten and pour it into the mold cavity through the pouring basin.

5. Cooling and Finishing: Allow the metal to cool and solidify, then break the mold to retrieve the casting. Trim and polish the final piece for finishing.
