What is Metal Casting?

Metal casting is a manufacturing process where molten metal is poured into a mold to create parts and components of various shapes and sizes. After cooling and solidifying, the metal takes the shape of the mold. This process is one of the oldest methods of metalworking and is widely used in industries like automotive, aerospace, and construction.

How Does Metal Casting Work?

Question: What are the steps involved in metal casting?
Answer:

1. Mold Preparation: A mold, usually made of sand, metal, or ceramic, is created to define the part's shape.

2. Melting Metal: Metal is heated in a furnace until it becomes molten.

3. Pouring: The molten metal is carefully poured into the prepared mold.

4. Cooling: The metal is left to cool and solidify in the mold.

5. Removing the Casting: Once solid, the part is removed from the mold.

6. Finishing: Any excess material is trimmed, and the surface is polished or treated as needed.

Types of Metal Casting

Question: What are the common methods of metal casting?
Answer:

1. Sand Casting: Uses sand molds, ideal for large and complex parts.

2. Die Casting: Involves high-pressure injection into a metal mold, perfect for mass production.

3. Investment Casting: Creates precise components using wax patterns and ceramic molds.

4. Centrifugal Casting: Spinning molds form cylindrical parts like pipes.

5. Permanent Mold Casting: Reusable metal molds are used for consistent shapes.
