1. Sand Casting

Sand casting is one of the oldest and most widely used metal casting processes. It involves creating a mold from a mixture of sand and a binder, into which molten metal is poured. This versatile method is suitable for both simple and complex shapes, making it a preferred choice in various industries.


2. Investment Casting

Investment casting, also known as precision casting, utilizes wax patterns that are coated in a ceramic shell. The wax is melted away, leaving a mold cavity that is then filled with molten metal. This process is ideal for intricate and high-precision components, often used in aerospace and medical industries.


3. Die Casting

Die casting involves forcing molten metal into a mold cavity under high pressure. This process is known for its ability to produce detailed and dimensionally stable parts. Commonly used materials include aluminum, zinc, and magnesium. Die casting is prevalent in the automotive and electronics industries.


4. Centrifugal Casting

Centrifugal casting utilizes centrifugal force to distribute molten metal into a mold cavity. This process is particularly effective for producing cylindrical components like pipes and tubes. The controlled rotation ensures a uniform distribution of metal, resulting in high-quality castings.


5. Continuous Casting

Continuous casting is a method where molten metal is continuously poured into a mold and solidified in a continuous process. This technique is commonly used for casting large volumes of metal with a consistent quality. It is prevalent in the production of steel and aluminum.
