Sand Casting

  • Versatility: Well-suited for a wide range of metals and alloys, providing flexibility in material selection.
  • Low Cost: Initial tooling and setup costs are generally lower compared to investment and die casting, making it cost-effective for small to medium-sized production runs.
  • Large Parts: Suitable for casting large and heavy parts due to the adjustability of mold sizes.

Investment Casting

  • Precision and Detail: Investment casting allows for the production of intricate and highly detailed parts with excellent surface finishes.
  • Versatility: Well-suited for a wide range of metals, including ferrous and non-ferrous alloys.
  • Low Material Waste: The process generates minimal material waste as the mold is only a thin ceramic shell.

Die Casting

  • High Production Rates: Die casting is highly efficient for large-scale production, offering high-speed casting of complex parts.
  • Dimensional Accuracy: Provides excellent dimensional accuracy and tight tolerances, making it suitable for precision components.
  • Surface Finish: Die casting produces parts with a smooth surface finish, reducing the need for additional machining.
