• Sand Casting: This is the most common method, where molds are made using sand. It’s cost-effective for producing large parts but offers lower precision compared to other methods. It’s typically used for larger, less intricate components.
  • Investment Casting: This process uses a wax pattern, which is coated in a ceramic shell that hardens. Investment casting provides high precision and is ideal for small, complex, or intricate parts. It’s more expensive but yields finer surface finishes and greater dimensional accuracy.
